Best solar generators for off-grid living ranked by most important performance categories

Before covering more details of each system, I want to discuss the average power consumption of the listed off-grid living styles (RV, cabin, camper van).

This will give you an estimate of the number of batteries you’ll need to have to run consistent off-grid power.

Average Off-Grid Living Power Consumption

airstream with morning sun background
RVs and travel trailers consume 20kWh/day on average

An off-grid cabin’s energy consumption varies greatly, but a large cabin with energy-efficient and/or downsized appliances (compared to a typical home) will use about 22.5kWh per day. This is 75% of the average 30kWh per day used by a regular home.

Considering that the average off-grid home needs about 7,000W (7kW) of solar panels to run entirely off the grid, this equates to daily solar energy production between 17.5 and 28kWh (50-80% solar panel efficiency).

The number of solar panels needed can be offset by using propane tanks, gas generators, or wind turbines to power various appliances.

A camper van’s energy consumption will fall between 2.5-4.5kWh used daily. This depends on the various appliances in the van as well as their energy efficiency. The air conditioner tends to consume the most power compared to other appliances in the vehicle.

The average RV or travel trailer uses about 20kWh of power every day when in use.

  • RV/Travel Trailer: 20kWh/day (source)
  • Off-Grid Cabin: 22.5kWh/day – I took 75% of average home power consumption of 30kWh (source)
  • Camper Van: 3.5kWh (source)

Since the amount of power used varies greatly depending on your own off-grid living situation, I highly recommend that you calculate your average consumption using a simple calculator tool.

This will align you to exactly which system will work best for your needs.

Daily Electricity Usage Offset Using Solar Generators

Solar generators can offset a significant amount of overall power consumption

Based on the averages above, I compiled a table illustrating the percentage of power that each solar generator can deliver in a single day.

I included the standard/baseline battery capacity of each unit along with its maximum available battery capacity from utilizing additional external batteries.

Point Zero Energy Titan2-unlimited kWh8.9-100%10-100%57.1-100%
*Battery capacity range: Refers to how much the solar generator can expand with additional batteries

There are a few things I want to discuss regarding the above numbers because (obviously) not all cabins, RVs, and camper vans are the same:

  • In order for all appliances to run successfully with your system, you may need more than one main power module
  • The amount of extra batteries and power modules needed depends on how often you intend to use RV/cabin/van
  • Please note that summer months will most-likely have higher energy use
  • The cost of creating the largest possible solar generator system will be significant

As mentioned prior, the practicality of using a solar generator system for living completely off-grid depends on your financial and power requirements.

That being said, let’s dive into each of these power stations in more detail.

1. Bluetti EP500Pro

EcoFlow Delta Pro

The Delta Pro is EcoFlow’s first portable power station with a lithium-iron-phosphate battery.

With a long-lasting battery setting the foundation for the Delta Pro, its input and output power combined with its unique and user-friendly features make it one of the most versatile large solar generators you can buy.

You can monitor it with the EcoFlow app and recharge it from an EV charger (unique to the Delta Pro). Its 1,600W solar input and EV charging input allow you to charge it on the road with ease, while its 30A output ports support RV power needs.

The EcoFlow Delta Pro is the best solar generator for an RV because it has an AC inverter rated at 3,600W continuous (7,200W surge), 30A AC outlet, 30A Anderson port, battery expansion (up to 25kWh), and can run 240V appliances by pairing two Delta Pros together with EcoFlow’s Double Voltage Hub.

One of its many strong suits is its ability to connect to up to two external batteries (10.8kWh total).

If you want even more power, you can connect multiple Delta Pros together to have an off-grid system with up to 25kWh of battery storage.

The Delta Pro clearly offers several benefits for off-grid living.

Not only does it have a huge amount of accessible AC power, but it also has the recharging capabilities that benefit RV users (solar plus EV charging).

Depending on what you need, you can create a solar generator setup that is simple or add batteries and modules to support multiple high-powered appliances.

Being integrated with the EcoFlow app, the Delta Pro can be managed from your phone. The app lets you adjust several features to customize your system to your liking.

I’ve used the EcoFlow app for my River 600 Max and it really enhances how I can use it. If you want more details on the app you can read my review of my River 600 Max here: EcoFlow River 600 Review – Testing My River Max + Comparisons.

Delta Pro – Pros & Cons

Highest AC power output availableExpansion batteries don’t stack on top of one another
Multiple unique features (mobile app, UPS, split phase bonding, etc.)1,600W solar input is good, but adding more batteries will significantly increase recharging times
Can be recharged from an EV chargerHeavy (99 lbs)

One word to describe the Delta Pro is versatile. It supplies as much power as you need for several devices and appliances.

Not only that, but its efficient LiFePO4 battery will provide a long usable lifetime off the grid.

3. Bluetti AC200MAX

Bluetti AC200MAX

At 62 pounds, it may be a surprise that this solar generator is the lightest of the options in the top four.

Being nearly 40 pounds lighter than the Delta Pro, this system is more reasonable to work with when limited space is available, such as inside a van conversion.

The Bluetti AC200MAX is the best solar generator for van life due to its 2,200W AC inverter (4,800W surge), which is fit for most van conversion power needs, such as mid-range AC units and cooking appliances. It also has five USB ports and four 12V DC outputs for devices and DC power needs.

If more battery capacity is needed, you can connect up to two of Bluetti’s B230 or B300 expansion batteries.

With two B300 batteries attached, the AC200MAX has 8.2kWh of available battery capacity.

WEIGHT62 lbs
DIMENSIONS16.5 x 15.2 x 11 in

At its longest measurement, this power station is nearly 10 inches shorter than the EcoFlow Delta Pro’s equivalent.

With its smaller dimensions and lighter weight, the AC200MAX is easy to maneuver than the Delta Pro (although it doesn’t have wheels).

This power station offers the same touchscreen and Bluetti application for mobile use as the EP500Pro.

The AC200MAX also has two 30A output ports, including a 120V RV port and a 12V “Super DC” port.

A unique feature that often gets overlooked is its port covers. All of the AC200MAX’s input and output ports have covers.

These covers protect the system from getting water/dust damage and are surprisingly rare to find in most solar generators.

AC200MAX – Heating and Air Conditioning for Van Life

Camper van outdoors on sunny day
Camper vans and other small campers need heating and AC – both use a lot of power

Although mini-fridges and other small kitchen appliances consume a good amount of power in a camper, heating and air conditioning use the most power because they both:

  • Use a high amount of continuous power
  • Are generally used for extended periods of time

This combination creates the need for a solar generator that can supply a high power output for a long time.

Air Conditioning for Van Conversions – AC200MAX

Air conditioning is by far the largest energy user for any van conversion. However, this applies mainly to roof air conditioning units, which seem to consume a minimum of around 1,500W continuously.

There are several different AC units that you can use for your van, but any air conditioner other than a rooftop one will save you a ton of power consumption.

The main question is if a smaller AC unit will be enough for your needs.

If you already have or intend to have a rooftop AC unit for your van conversion, then I recommend the EcoFlow Delta Pro because its power output is significantly higher and can handle most high-demand rooftop AC units.

Similar: Can a Solar Generator Run an AC Unit?

Van Life Heating Options With the AC200MAX

Heating options are much easier on power consumption than rooftop AC units. You’ll find that most space heaters use at the most 1,500W.

Another option is a heated blanket. These use far less power than a typical space heater (40-60W). For the most efficiency, you could opt for heated blankets and a small 500W space heater instead of a 1,500W heater.

If you intend to use a standard 1,000-1,500W heater for your van, I recommend getting an additional battery or batteries to add to the AC200MAX.

This is because one of these heaters running at full power will only last about an hour and twenty minutes with a full AC200MAX battery.

Getting a Bluetti B230 external battery will give you about three hours of run time, and the B300 battery will give you 3.5 hours total with the 1,500W heater on full blast.

If you need more battery power, you can add two external batteries for a longer running time with a heater.

Bluetti AC200P

The AC200MAX is an updated version of the AC200P. There are several upgrades to the AC200MAX versus the AC200P, a few of which are:

  • Improved continuous AC power output (2,200W vs. 2,000W)
  • 120V/30A RV port (not in the AC200P)
  • Battery expansion options (not in the AC200P)
  • Improved solar input (900W vs. 700W)

The AC200P is an excellent power station if you don’t need extra battery power. You can check out the AC200P on Amazon here (affiliate link). It will cost you about $400 less than the MAX version.

More information on the AC200P can be found in my comparison article, where I compare it to the first generation AC200 solar generator. You can read it here: Bluetti AC200 vs AC200P – Key Differences & Takeaways.

AC200MAX – Pros & Cons

Diverse output options (16 total)Doesn’t have wheels (weighs 62 lbs)
Battery expansion available (up to 8.2kWh)Won’t last long with high-powered appliances

The AC200MAX provides a high amount of power with a mobile application, battery expansion, and versatile port options.

If you don’t need a ton of power (like the Delta Pro and EP500Pro deliver) from AC ports and could use a system with a smaller footprint, this is the best option available.

4. Point Zero Energy Titan

Titan solar generator front view
Titan solar generator

Over a year before the EP500, Delta Pro, and AC200MAX came out, the Titan set the solar generator standard in several areas.

Although it doesn’t have a mobile application, USP function, or split phase bonding (among other technologically advanced features), it does have the solar input, AC power output, and battery expansion capabilities and features that make it either compete or stand alone amongst the newest large power stations.

With a higher solar input than the Delta Pro and versatile battery storage, the Titan can recharge fast and provide several appliances/devices with power.

Since it has a 2,000W solar input with two or more batteries attached, space is needed to install solar panels to achieve maximum power.

The panels are ideally used on a rooftop or open field where sufficient sunlight is available throughout the day.

The Titan is the best solar for off-grid cabins because its batteries stack on top of one another (conserving space) and you can add an unlimited number of batteries to it. With two or more batteries, the Titan takes in up to 2,000W of solar input. However, it cannot power 240V appliances.

Both the Delta Pro and EP500Pro can power 240V appliances, but both require you to use two power stations in order to access this amount of power.

If you intend to use a solar generator with 240V for appliances, then the Delta Pro (x2) or EP500Pro (x2) are the best options.

However, the Titan is the best option for cabins if you need it for 120V power needs such as:

  • Lighting
  • Fans
  • Refrigerators

For an idea of what the Titan can power (and for how long), I have an article putting the Titan through a realistic power test over a three-day period.

I use a full-size refrigerator, lighting, and other devices/appliances in this test. This article will show you how it can be sufficient for powering your off-grid cabin. Read it here: 3 Best Solar Generators for Your Fridge (With Run Times).

- Can connect 3rd party batteries
WEIGHT67 lbs
DIMENSIONS18.5 x 12 x 12 in

The main features that set the Titan apart from the others in this list are the following:

  • It takes in over twice the amount of solar input as the AC200MAX (with 2+ batteries) at 2,000W
  • It takes in 400W more solar input compared to the Delta Pro
  • It has the ability to expand its battery in a modular fashion, where you can stack them on top of each other
  • You can expand its battery size to as large as you want

Since it can charge up from solar panels at a rate that is second to only the Bluetti EP500Pro, it is a versatile power station for an off-grid cabin.

The fast solar recharging element makes it a reliable power source but you will need a good amount of space for the solar panels to be installed.

Plus, stacking the batteries on top of each other will allow you to store the power station easily, which is a trait that none of the other ones have.

One major difference that the Titan has compared to the others in this list is that it lacks a mobile application.

Furthermore, its LCD screen doesn’t have nearly the amount of features that the others provide.

These make the Titan more of an analog power station, where you set it up and let it run. However, if you run into issues, it will take longer to understand the problem and solve it if you’re new to solar generators.

If you run into issues that can’t easily be solved, the Titan user manual has a list of problems and solutions to better guide you to a solution.

Titan – Pros & Cons

High AC power outputCannot run 240V appliances
19 port options availableNo mobile application
Unlimited, stackable battery expansionExpensive compared to similar systems

The Titan has features that make it exceptional for certain power needs. High solar input power, stackable batteries, and an unlimited number of batteries to connect to the Titan all make it unique.

For 120V power needs, this solar generator can easily run appliances and electronics for extended periods of time.

For more details on the Titan, I created an article going into more depth on what it can do. Since this system is quite different from the rest on this list, my review highlights its features and compares the Titan to other similar power stations. You can find it here: Titan Solar Generator Review – The Best Large Solar Generator?.

Below I also have multiple comparisons to the Titan to give you a better perspective on if it’s right for you:
