All of the solar generators in this list have lithium-ion batteries. For a longer-lasting solar generator lineup, I wrote an article on the best LiFePO4 solar generators.

These models have batteries that can last over ten times longer than lithium-ion ones. If you’re interested, you can check it out here: 6 Best LiFePO4 Solar Generators (Stats, Pricing, and Analysis).

Jackery Explorer 240 – Best Small Solar Generator for the Home

Jackery Portable Power Station Explorer 240, 240Wh Backup Lithium Battery, 110V/200W Pure Sine Wave AC Outlet, Solar Generator (Solar Panel Not Included) for Outdoors Camping Travel Hunting Emergency

The Jackery Explorer 240 is a small solar generator that is about 2-3 times bigger than a large portable power bank.

With its easy to carry shape and size, eco-friendly setup, and quiet nature, the Jackery 240 is an excellent companion for the outdoor lifestyle.

It has a lithium-ion battery that gives out up to 200W of continuous power. This allows you to power multiple devices simultaneously from its various output ports.

Key Features

1. More than your Average Battery Pack

The Jackery 240 is packed with a 240 watt-hour (16.8Ah, 14.4V) lithium-ion battery pack. That’s enough power to charge your smartphone 10-20 times over. This battery can also be useful for:

  • Charging camera batteries
  • Charging laptops and tablets
  • Powering lights

2. Solar-Ready

The Jackery Portable Power Station Explorer pairs excellently with Jackery Solar Saga 60W/100W solar panels for efficient off-grid recharging.

Please note that the solar panels are sold separately from the device.

Solar charging can come in handy when there are power outages at home. With the 60W panel from Jackery, you can recharge the entire system in about five hours. Since the average amount of quality sunlight during the day is around five hours, the Jackery 240 will be able to fully recharge during the day to power any equipment you need during the nighttime.

This benefit outweighs most portable solar chargers because they have very small solar panels attached to them, resulting in very slow recharge times.

Since the Jackery 240 can take in as much as 10-times more watts than portable solar chargers, it will be able to be a useful tool for extended off-grid use. 

3. Lightweight

Weighing 6.6 lbs, the Jackery 240 can be carried around the house with ease.

Most of the weight (as with all solar generators) comes from its battery. Its ability to be under seven pounds is due to its lithium-ion battery, which has a high energy-density framework.

Lead-acid batteries are much heavier. For example, the Yeti 150 is a similar solar generator to the Jackery 240, but it uses a lead-acid battery. This results in a system that weighs 12 lbs, nearly twice the weight of the 240!


The Jackery 240 is designed for charging laptops, drones, mini-coolers, and a host of other electronics. The device features:

  • One AC outlet (110V, 200W, 400W peak)
  • One DC cigarette lighter port
  • Two standard DC outputs
  • Three standard USB-A ports

Package Details

  • (1) Jackery Explorer 240
  • (1) AC adapter
  • (1) car charger
  • User guide


This solar generator is portable, noiseless, and provides sufficient energy for the charging of all your small devices. Its various outputs allot you versatility when charging. Charging the Jackery from solar panels can allow you to use it consistently and frequently when the power goes out at home.

EcoFlow River 370 – A Small (Yet Powerful) Home Solar Generator

EcoFlow River 370 Front and Back
EcoFlow River 370

The EcoFlow River is a 370Wh solar generator that is a step up from the Jackery 240 in both its battery size and AC port power. Its inverter (for the AC ports) can power up to 300W of devices continuously with a surge power rating of 600W max.

Key Features

1. Charging Methods

The River 370 comes with a single AC charger that charges the River through the USB-C port on the front of the system. With this charger, its battery will be full in about seven hours.

You can reduce this recharging time down to about four hours by purchasing a second AC to USB-C charger (since there are two USB-C PD ports on it).

If you’re at home with no power and need to recharge the system, you can connect one or two of EcoFlow’s 110W solar panels to the USB-C ports to recharge in about the same times as the AC wall chargers would.

The 110W panels may seem like too much power coming into the River, but the charge controller within its frame will adjust the power from the panels to be able to work seamlessly when connected to its USB-C PD ports.

2. Nine Outputs

The EcoFlow River has the ability to charge up to 9 devices at a time, including:

  • (2) AC outputs (300W continuous, 600W peak)
  • (2) 60W PD USB-C ports (this feature supports most laptops)
  • (2) Fast-charge USB-A ports
  • (2) Standard USB-A ports
  • (1) 12V cigarette lighter port

The device can also be used while it is being recharged. This is important because if you have a power outage at home and would like to recharge the River 370 from solar panels, you can do this while also keeping your smartphones and lights charged and running simultaneously.

3. Safe

The Battery Management System (BMS) enables voltage and temperature control as well as other advanced safety measures to make sure you can use it effectively with ease.

4. LCD Display

The device has an LCD screen that can display the operational information of the device. Operational information includes battery levels, remaining charge time, output watts, input watts, and other important information.

Having input watts is an important feature to have when charging from solar panels so you can gauge what angles work best when placing the solar panel towards the sun.

5. Lightweight

The EcoFlow River 370 might not be as light in weight as its peers (11 lbs), but it is still a portable solution to power outages at home. Its carrying handle on top of the system makes it simple to carry from room to room if needed.

It can also be stored for several months in storage when not in use, so you can have a reliable power backup when the power goes out.

Package Details

  • (1) EcoFlow River 370
  • (1) Wall charger
  • (1) Car charger
  • (1) USB-C cable


EcoFlow provides all customers with warranty coverage of 18 months and 24/7 friendly customer service support.


The River 370 makes sense for a small power backup at home and its main benefits include its multiple output ports, fast recharge times, and inverter (AC) output.

Its USB-C PD ports and four USB-A ports set it apart from the Jackery 240’s three USB-A ports, allowing for more devices to be charged all at the same time.

I addition, its LCD display is easy to read and includes several valuable metrics to use when off the grid or when recharging via the AC charger.

The EcoFlow River 370 has been discontinued by EcoFlow. In its place is the EcoFlow River (also known as the EcoFlow River 600).

There are several variations to the new River solar generator, including a high-powered AC inverter, high solar input, and fast AC recharging.

Check it out in my EcoFlow versus Jackery article, where I compare this system to Jackery’s power stations: EcoFlow vs. Jackery – Full Solar Generator Comparison (With Specs).

Rockpals 500 – A Good Home Solution (Especially for CPAPs)

Rockpals 540Wh generator front view
Rockpals 500 (540Wh version)

The Rockpals 500 is a 540Wh solar generator powered by a lightweight lithium-ion battery. It has two 110V AC outlets, a cigarette lighter output port, two DC output ports, multiple USB ports, and several other features that will make it ideal for home use during a blackout.

This solar generator also has a twin, which also falls under the same “Rockpals 500” title. It has 520Wh of battery capacity and has similar features. Check out that review and comparison to the 540Wh version here.

Key Features

1. Power Output

The Rockpals 500 has a tremendous AC output for its size, at 500W continuous (1,000W peak surge).

The ports on the outside of the device are comprised of:

  • (2) DC ports (12V/48W max)
  • (1) Cigarette lighter port (12V/96W max)
  • (1) Quick charge USB-A port
  • (2) Standard USB-A ports (5V/2.1A/10W max)
  • (1) USB-C port (18W max)

The device powers up phones, tablets, laptops, cameras, walkie-talkies, CPAP machines, among several other gadgets (with an input below 500W for the AC port). 

2. Very High Capacity Lithium Power Pack

The Rockpals 500W portable power station has 540Wh (10.8V/50Ah) of capacity from its lithium batteries, with a 12 lb weight.

The battery can sufficiently charge smartphones about 58 times and laptops (56W) about 7-8 times. It can also run mini car refrigerators (75W) for about 5-6 hours and mini projectors (60W) for about 6-7 hours. 

3. Efficient for Emergency Power Supply

With a build that assures efficient delivery of power and an immense power output, this device is a must-buy if you are considering a small home-backup solution for your devices.

Communication is key in a crisis, so ensuring that you have some sort of battery recharging source is crucial for when there’s no power at home.

Lastly, this portable power station is not just any standard battery that can recharge your phone a couple of times. It has much more power than that, ensuring that if you need more of it, it will be able to supply it effectively to your devices until your power comes back on.

4. Easily Rechargeable

You can recharge the Rockpals 500 off the grid using the Rockpals 100W solar panel (affiliate link). Please note that the solar panel is sold separately.

Charging time is usually 6 to 7 hours under good sun conditions.

The battery power supply can also be fully charged by a 12V car charger in about 6 to 7 hours. (Please note that the cable is not sold with the device.) 

Lastly, from an AC wall charger, the Rockpals 500 can be charged in the same 6 to 7 hours as the other charging methods.

Having the same charging times with all charging methods is convenient since it will be predictable when the system will be at its full capacity.

5. LCD Display and Ultra-Bright Emergency Light

Besides its inputs and outputs, the Rockpals 500 provides you with a bright emergency light for sudden power outages and an LCD display that shows important on-screen information, such as battery capacity, an over-temperature indicator, AC output power/load, and a battery failure alarm.

6. Safety

The Rockpals 500w Portable Power Station has a pure sine wave inverter, ensuring safe charging of power-sensitive devices like a laptop. This feature protects these devices from damage because pure sine waves allow for a smooth transition of power from the solar generator’s inverter to your devices. The other inverter style (that’s not in the Rockpals 500) is called modified sine wave technology, which tends to be tricky to use with a number of devices and appliances.

Equally, the BMS (Battery Management System) allows for short circuit protection, temperature control, voltage control, and even more advanced safety measures. 


The Rockpals 500 portable power station has a warranty that covers up to 18 months.


This solar generator has an impressive AC output that far exceeds the previous models mentioned. This is very useful for powering several devices at once or for powering a larger device/appliance that runs under 500W.

With a large battery with over 500Wh, the Rockpals 500 will be able to run for an extended period of time with small device charging. An emergency light will be helpful to navigate in the dark and can be used to help insert devices into its ports. The several output ports allow for several devices to be charged simultaneously, making it great for a family’s needs.

Rockpals has three 500W solar generators and unfortunately the one mentioned in this article is not longer available. A similar version to the one mentioned here is still available.

I have a comparison piece where I discuss the similarities and differences of these two models in this article here: Rockpals 500 Review (In-Depth) – Features, Specs, and More.

You can find the Rockpals 500 (updated version) via Shop Solar Kits here (affiliate link).

The third Rockpals 500 power station is their newest iteration of the three and it is called the Rockpower 500. I personally tested this system and it is lightweight and inexpensive compared to similar models from other brands.

I have a review of this model as well and you can read it here: Rockpals Rockpower 500 Review (Testing, Pricing, and More).

Key Features

1. Multiple Device Charging

The 1,425Wh Yeti 1400 has the capacity to power up to 10 devices all at once, giving you several options when using it at home for backup purposes or for using with the grid to lower electric utility costs.

The 1400 Lithium charges small devices easily, such as:

  • Smartphones
  • Tablets
  • Laptops
  • Drones
  • Camera batteries

It can also be used with more demanding appliances such as:

  • Refrigerators
  • TVs

This Goal Zero Power Station will always be the perfect fit for all your indoor and outdoor backup or emergency power needs.


Sitting at over 1,400Wh of battery capacity, the Yeti 1400 is going to last for a long duration when the power goes out at home. If high power demands are needed, this system is also useful as it can provide a significant amount of continuous power to run TVs, fridges, microwaves, and other similar appliances/electronics.

You can check out my in-depth analysis of the 1400 Lithium here, however, this Yeti power station is no longer available for purchase.

I recommend reading my Yeti 1400 vs. 1500X article as the 1500X model is the successor to the 1400 Lithium. It has a better AC inverter as well as faster AC and solar recharging to name a few highlights.

Read this comparison piece here: YETI 1400 vs 1500X – Goal Zero’s Solar Generator Giants.

Yeti 3000 Lithium – A Yeti 1400 With Twice the Battery Capacity

Yeti 3000 Lithium front view
Yeti 3000 Lithium

The Goal Zero Yeti 3000 Lithium is yet another industry standard generator alternative with 3,075Wh of lithium battery storage.

The power station provides the same amount of power from its inverter as the 1400 Lithium, with up to 1,500W of continuous power, and 3,000W of surge power.

Other than its high efficiency, relatively short charging time, and various output options, this device is also installed with the Yeti application, allowing for remote control via Wi-Fi and a mobile phone.

Key Features

This device is packed with 10 versatile output ports, giving users varied options for charging.

1. Pre-Installed MPPT Charge Controller

The Yeti 3000 Lithium has a pre-installed maximum power point tracking (MPPT) charge controller, giving up to 40% increased charging efficiency.

Overall, you get two charge controllers with this system. It already has a PWM charge controller built into it, but the MPPT module is included with the purchase of a Yeti 3000 Lithium. This MPPT module has one Anderson Powerport input (or as Goal Zero calls it, a High Power Port) along with two 8mm input ports.

The High Power Port (HPP) can be used with solar panels to charge your Yeti at a much faster rate than with the standard HPP input port alone. The 8mm inputs can be used with Goal Zero wall chargers, car chargers, or solar panels.

2. Roll Cart Included

This device comes with a roll cart that has wheels and a telescoping handle to make it easier to move around. The power station weighs about 79 lbs with its roll cart and MPPT charge controller attached. This is clearly a heavy load for any one person to carry.

Having a roll cart enables one person to transport it with ease. However, it will be a lot of weight to hoist into a car or down and upstairs at home. For this, the Yeti has two carrying handles that can be used to carry it up and down surfaces where the roll cart cannot serve.

3. Safety

The Yeti 3000 battery is built with quality and safety in mind. The lithium cells are stable and are monitored by a thorough battery management system (BMS) that protects the device from overcharge, unbalanced current (output and input), and short-circuiting.


This system is ideal for use at home as a backup solar generator during an unexpected power outage. With its large battery and high-powered AC outputs, you can power several different devices and appliances for a long time until the power comes back on.

The Yeti 3000 also can be used to lower utility costs by using it to power specific appliances at home, like the refrigerator. Its Wi-Fi connectivity is also a versatile tool to use to keep track of its input and output when in use.

As with the Yeti 1400 Lithium, Goal Zero has discontinued this model to make way for their newer solar generator called the Yeti 3000X.

I show you the differences of both systems in my comparison post found here: Goal Zero Yeti 3000X vs Yeti 3000 Lithium (Ports, Features, & More).

Titan – Best Large Solar Generator for the Home

Titan solar generator front view
Point Zero Energy Titan

The Point Zero Energy Titan remains one of the most powerful solar generators ever made.

This expansive solar generator sits at 67 lbs (with one battery) and can power several different appliances and devices. It even has an RV output port to power appliances within an RV!

Having a modular design, the Titan can expand its battery capacity easily by adding additional batteries to the bottom or to the side of the solar generator.

Each battery is capable of about 2,000 charge cycles to 80% capacity, which is one of the highest charge cycle rates among the competition for lithium-ion batteries.

Key Features

1. High-Powered and High Capacity

The Titan solar generator carries a 2,000Wh lithium-ion battery and can draw 1,500W continuous and 3,000W of surge power with one battery.

The inverters’ continuous power output with two batteries or more can get as high as 3,000W continuous and peak at 6,000W. This output capability makes it the ideal solution during any form of emergency power crisis at home.

2. Fast Recharge

The Titan can get recharged at an extremely fast rate from solar and AC charging. This is because it has a 600W AC wall charger and is capable of up to 1,000W of solar input when there is one battery attached to its module.

However, with two or more batteries attached, you can double both the AC and solar recharging times to 1,200W from the wall and 2,000W from solar panels. This is because the Titan has two Anderson Powerpole inputs for solar panels (1,000W each) and two wall-charging inputs (600W each).

The Titan comes with an AC charger, but you will need to purchase an additional AC charger if you want to get the fastest possible AC charge times.

With the maximum solar input with one battery (1,000W) or two batteries (2,000W), the Titan will recharge completely in as little as two hours! This is one of the fastest-charging solar generators for its size.

The AC charging with one battery and one AC charger (600W) or two batteries and two AC chargers (1,200W) will fully charge the Titan in about four hours. As with solar charging, this is one of the fastest-charging solar generators from wall outlets.

3. Two MPPT Charge Controllers

This device is installed with two MPPT charge controllers and protects the Titan from overcharging and short-circuiting.

Say you have one battery with a maximum solar input at 1,000W. If you have 1,100W of solar input coming in, the MPPT controller will be able to downgrade the input to its maximum of 1,000W. This gives you safety and versatility with this system.

4. Simultaneous Charging

You can recharge the Titan using all three of its charging methods (car, wall, and solar). This is a great feature that is not standard amongst its competition.

This allows you to charge your system at a fast rate and can also give you versatility if you only have a few solar panels and could use the boosted recharging power from adding an AC charger or car charger input.

5. Shelf-Life Before Recharge

The Titan can last up to five years in storage without needing to recharge it. If you are considering using this system and storing it only for power outages, make sure to charge it completely before storing it. This will keep the battery secure and allow it to retain as much of its battery life as possible for when you need it most.


With the Titan, you can power several different devices and appliances with ease. This is the most powerful and longest-lasting solar generator in this article. Its 2,000 cycles to 80% battery capacity will let you use it for years to come. With two batteries, this generator is one of the most powerful in the industry, tying the Bluetti EP500Pro for 3,000W continuous and 6,000W surge power from its AC ports.

This is by far the ideal solar generator to have for your home either to use during a power outage or to use it with your grid power to lower utility bills.

Flex AC Portable Power Station – Versatile & Powerful

The Flex 1500 power station is a portable yet powerful solar energy platform from Inergy. You can keep it portable by having just one battery attached to it, where it would weigh about 30 lbs. Or, you can add several batteries to the system for your home, RV, or off-grid cabin for a much more reliable power system.

Inside the Flex is an MPPT charge controller for more efficient charging.

Key Features

The Flex has a 1,500W continuous and a 3,000W surge power capability. It also uses a pure sine wave inverter for a smooth energy transfer to your gadgets and appliances.

DC power is regulated at 13.8V, and it allows full usage of 12V devices like portable refrigerators, pumps, amongst other DC-powered equipment.

You can also purchase an MPPT Supercharger from Inergy, which gives you about three-times the standard input charging power.

1. Modular Design

Like the Titan, the Flex has a modular design where you can attach multiple batteries to the bottom of the power module or to the side of it. Each battery has 1,069Wh of battery capacity and easily connects to the bottom of the power module.

Having this feature allows you to both expand or contract your Flex to your needs. So if you want portability, you can have just one battery; or, if you want a high-grade system for extended off-grid use, you can have up to 96 batteries attached to your generator.

2. Flex AC and DC Modules

There are two different modules available from Inergy, the AC and DC version. The AC version has six AC ports along with several other port options. However, the DC version has zero AC ports, and replacing these are multiple car outputs, USB ports, and Anderson Powerpole connections.

Regardless of which version you choose, the batteries are interchangeable.

System Specifications

  • AC Inverter: 1,500W continuous, 3,000W surge. 
  • It combines multiple charging sources at once, such as the 14-90V DC Solar input, car charger input, standard wall charger input, and optional Flex MPPT supercharger. 
  • Lithium Battery Expansion: The Flex can take up to 96 Flex batteries (5 Flex Batteries per vertical stack.) 
  • MPPT Charge Controller: The Flex has a 14-90V DC solar input with a maximum 30A charge rate. 
  • Can accept either series or parallel wiring configuration at a 90V DC input maximum; however, there is no average input maximum. 
  • Dimensions: 14 by 8 by 8.9 inches. 

Package Details

  • (1) Flex 1500 power console
  • (1) standard wall charger
  • (1) flex battery
  • (1) user manual


With its modular design and powerful inverter, the Flex is extremely versatile to bring around the house (with one battery) or to connect to multiple batteries to power part of your home when the power goes out.

The system can power appliances rate at or below 1,500W, which can be a game-changer if you’re in need of a lot of off-grid power.

If you need some extra security to make sure you get a consistent full battery while off the grid, you can connect the Flex with an MPPT Supercharger to increase its solar panel input three-fold.

In addition, you can get the Flex DC module instead of the AC version, which could be used with several DC appliances and electronics.

Overall, the Flex is one of the most versatile solar generator systems that meets several different user needs.

The Titan and Flex power stations have similar modular designs. The main areas to decide which one is best for you probably revolve around pricing, power options, and recharging times.

These solar generators should give you some good options to choose from and allow you to get the power you need for whatever electronics or appliances you intend to run with these systems.

With a nice solar panel setup, you will be taken care of when you have a backup battery system at your side.

In the case of a power outage at home, all of these solar generators will be able to support (at the very least) charging your smartphone. The higher-end solar generators mentioned (1,000Wh and up) will be able to power more demanding appliances if and when you need them powered.

It is always a good idea to mitigate the risk of having no power due to a grid power outage. With a solar generator at your disposal along with some good solar panels, you’ll be able to have the power to carry out tasks for yourself and your family until the power returns at home.

Overall, the best option of these listed is the Titan solar generator because it is better in almost all important categories compared to other systems.

  • Its battery capacity can expand to however large you need
  • Its solar input is among the highest in the industry
  • It has one of the most powerful AC inverters in the industry

For an idea of what it can power, I made an article discussing the best solar generators to run a full-size fridge and, of course, the Titan is #1.
