Bluetti vs. EcoFlow – Collective Solar Generator Deep Dive

Bluetti and EcoFlow are two of the top makers of solar generator systems today. Their innovative power stations range from small and portable all the way to partial home backup.

I’ll be comparing specific models and kits that these two companies offer in order to find out which brand holistically has the best power stations.

Bluetti has better large solar generators (2,000Wh+) compared to EcoFlow’s models, however, EcoFlow’s smaller River series is better than Bluetti’s current EB lineup due to a better user interface via its mobile app.

Below are my results gathered from my comparisons. You’ll find my reasons why the winning solar generator is better as well as a product link to the winning model .

Bluetti vs. EcoFlow Solar Generators – Key Differences

Conclusion #1 – Bluetti’s Batteries Last Longer Than EcoFlow’s

  • Bluetti has equipped nearly all of its current solar generators with LiFePO4 batteries, making them last longer than most models with lithium-ion batteries.
  • Out of the five power stations compared from each company, the Bluetti models’ average battery cycle life is double that of the EcoFlow models (3,600 vs. 1,820 cycles).

This is mostly due to the Bluetti EP500Pro since its battery is rated for 6,000 cycles (highest in industry).

Conclusion #2 – EcoFlow Power Stations Charge Faster from the Wall

  • EcoFlow’s X-Stream AC charging is available in all the models in this list, which is known to be the fastest AC charging technology in the industry.
  • The EcoFlow models in this comparison averaged a 30% higher wattage when charging from the wall, resulting in 30% faster recharging speeds compared to the Bluetti models.

Conclusion #3 – Larger Bluetti Models Have a Higher Solar Input Maximum

  • The first two sets of power stations compared (Bluetti’s EB series and EcoFlow’s River series) have the same 200W solar input max.
  • However, Bluetti’s two largest models both have a 50% higher solar input capacity when compared to the EcoFlow Delta Pro (2,400W vs. 1,600W).

For the fastest charging solar generators from both AC and solar charging, check out my post here: Top 3 Fastest Charging Solar Generators (Via AC & Solar).

Conclusion #4 – EcoFlow’s Power Stations are Lighter than Bluetti’s

  • On average, EcoFlow solar generators are 36% lighter than Bluetti models.
  • For each brand, I combined all five models’ battery capacities and divided this by their combined weight. Compared to Bluetti, for each pound of solar generator weight, the average EcoFlow power station contains an additional 10Wh of battery life.
  • In other words, this proposes that the batteries within EcoFlow’s power stations have a significantly higher energy density than Bluetti’s models.

Some of the lightest solar generators available come from Jackery. If an ultra-lightweight model is important to you I recommend reading my Jackery vs. EcoFlow breakdown here: EcoFlow vs. Jackery – Full Solar Generator Comparison (With Specs).

You can find out more of my experiences with the EB55 here in my review post: Test & Review: Bluetti EB55 Solar Generator (In-Depth).

EcoFlow River Max Overview

Front section of River Max
The front section of the EcoFlow River Max.

The River Max is basically a standard River power station with an additional battery. The added battery (which is detachable) brings twice the amount of battery life (576Wh) compared to the River (288Wh).

This makes the River Max extremely versatile. Since you can detach the additional battery (to make it into a standard River), you can use it for activities that may need more portability.

As seen from the table above, the River Max has all of the same ports as the standard River power station. This means a total of ten output ports – four of them being USB and three of them being AC ports.

Which Is Better Overall?

EcoFlow River Max next to Bluetti EB55
The EB55 and River Max have different strengths and weaknesses, but they share similar designs, power outputs, and port options.

The River Max is the better power station. In my experience with both models, they both perform well for input and output power. However, it’s clear to me that the River Max was built with slightly higher quality. It has a seamless interface that responds quickly to whichever button I press. Plus, its mobile app does a lot more than I thought for such a small system.

EcoFlow River Max Plus

The predecessor to the River Max Plus was the River Max, but this improved version has very similar attributes to the River Pro model, too.

The River Max Plus seems to be a mixture of both the River Max and River Pro. It has a removable battery pack like the River Max, but its battery is much bigger. In fact, its battery is the exact same capacity as the River Pro model, at 720Wh.

The River Pro has the ability to double its battery capacity via an external battery pack, but the River Max Plus does not.

One feature that can be easily overlooked is the River Max Plus’ battery cycle life. It has 800 cycles to 80% capacity, which is a significant increase from the River Max’s 500 cycles.

EcoFlow Delta Max Overview

EcoFlow Delta Max front and back
EcoFlow Delta Max

The Delta Max is the upgraded version of the original Delta 1300 model. It has more power in terms of input, output, and battery capacity than its predecessor.

With most of EcoFlow’s recognition currently coming from the popularity of the Delta Pro system, the Delta Max can be easily overlooked. It’s surprisingly powerful, with the 2nd largest single battery capacity in EcoFlow’s lineup.

This system also has a powerful 2,400W continuous AC inverter, a ridiculously fast AC charging speed of 1.6 hours, and an 800W solar input.

The Delta Max doesn’t carry all of the bells and whistles of the Delta Pro, but it holds strong in the areas that count: battery capacity, battery expansion, AC output, and recharging speed.

Since these solar generators are alike in battery size and output power, they can power the same appliances for nearly identical durations.

Which Is Better Overall?

The Bluetti AC200MAX is better than the Delta Max because it has more port options and a much longer battery lifespan. Its 3,500 cycles are over four times more than the Delta Max’s 800 cycles.

This basically means that if you were to use both systems in the exact same manner, the AC200MAX would last four times longer. This level of increased value supersedes the areas where the Delta Max outperforms the Bluetti.

This table compares the specifications of the Bluetti AC300+B300 to the EcoFlow Delta Pro. *(Recharging Times): The listed solar input and recharging time is based on the maximum solar input - not the solar panel rated power output (Ex: a 100W solar panel usually produces about 80W of actual power in good sunlight).

As you can see, there are several varying aspects amongst these power stations.

Bluetti AC300+B300 Overview

Bluetti AC300+B300 front view
Bluetti AC300+B300 front view.

With 19 total output ports, the AC300 paired with its B300 battery can charge and power several appliances and devices when you need power off the grid. Its one 30A and six 20A AC ports are among the most found on any solar generator system available.

Plus, you can connect AC300 modules to each other for up to 6,000W of output at 240V. This can be done via the Fusion Box Pro accessory, which has multiple 240V output ports.

The B300 battery pack was designed specifically for the AC300 module for battery expansion purposes. On the AC300’s side, there are two battery expansion ports that allow you to customize the battery capacity that’s best for your needs.

You can also use this power station as a 24/7 UPS with Bluetti’s Smart Home Panel that connects to your home. Plus, the Bluetti app allows you to review data and adjust the AC300’s performance to suit your home as best as possible.

EcoFlow Delta Pro front and back view.

EcoFlow’s top-of-the-line power station, the Delta Pro, is the largest single and largest expandable system from the company. It can expand its size to up to 25kWh of battery storage.

The first Delta power station, the Delta 1300, used EcoFlow’s X-Boost and X-Stream technologies and shocked the industry with how much power it could transfer. Now, the Delta product line includes the Delta Mini and Delta Max models – all with a similar design/layout.

The Delta Pro has a multitude of features and add-ons that can assist in creating a tailor-made backup power system.

Like its Bluetti competitor, it has the ability to double its output power for 240V appliances by combining two Delta Pros together. It also has an app that connects to your phone/tablet for a much more in-depth look inside the system’s functionality.

This table shows a list of various devices/appliances along with their run times when used with the Bluetti AC300+B300 and the EcoFlow Delta Pro power stations. NOTE: Estimates are my own calculations based on 1) 85% inverter efficiency for AC-powered devices/appliances, and 2) Discharge to 10% battery capacity (90% DoD).

The Delta Pro has about 500Wh of additional battery capacity over the AC300+B300. This helps it run appliances for ample amounts of time longer. Clearly, though, this depends on what you’re powering.

Which Is Better Overall?

The Bluetti model outshines the Delta Pro because of its ports and solar input power.

The biggest difference is in solar recharging, where the Bluetti can take in a massive 2,400W from solar alone. Although the Delta Pro is not by any means slow at solar charging, its capabilities when there are additional batteries in the mix can add up the hours needed to recharge it.

This table shows the winning traits of the AC300+B300 versus the Delta Pro. The Delta Pro is ideal for high-powered needs, but the AC300+B300 has the edge in solar input capability.

If you intend to leave your power station in one area permanently, I recommend the AC300+B300. If you intend to be more mobile (RV use), the Delta Pro is the better option.

Bluetti EP500Pro vs. EcoFlow Delta Pro (w/ Split Phase)

Pros and cons table for the Bluetti EP500Pro and EcoFlow Delta Pro kits. Each kit consists of two power modules and one split-phase adapter that connects them together. The Delta Pro kit in this example also contains one Delta Pro Smart Battery.

An important note to highlight is the EP500Pro’s inability to expand beyond 10.2kWh (two units paired together). Bluetti does not currently have expansion batteries available for this solar generator, but it’s possible that they will produce compatible ones in the future (they’ve done this with other models).

This table compares the specifications of the 10.2kWh Bluetti EP500Pro Kit (2x EP500Pros) to the 10.8kWh EcoFlow Delta Pro Kit (2x Delta Pros w/ 1x Extra Smart Battery). *(Recharging Times): The listed solar input and recharging time is based on the maximum solar input - not the solar panel rated power output (Ex: a 100W solar panel usually produces about 80W of actual power in good sunlight).

10.2kWh Bluetti EP500Pro Kit – Overview

Bluetti EP500Pro x2
Bluetti EP500 x2

When it comes to portable power stations that are simple to set up and use, the first brand that comes to mind is either Jackery or Goal Zero. I consider these companies’ products to be easy for most people to use. This is because they have fewer buttons and clear input, output, and LCD screen layouts.

However, in order to get more capability or customization in a solar generator system, simplicity tends to diminish. This is not the case with the Bluetti EP500. It has several features that go above the abilities of a standard power station, but its touchscreen and mobile app allow you to navigate sophisticated features with ease.

Aside from its simplicity, there are two additional features of the EP500Pro that are uncommon in the solar generator industry:

  • 6,000 charge cycles to 80% capacity: This rating shows how many times you can discharge and recharge your power station before its battery capacity lowers. The EP500 holds the highest cycle life rating in the industry today. This means that it will last longer than the other models available, further increasing its reliability and long-term value.
  • 5-year warranty: Most solar generator warranties are for two years. This is the longest warranty for a power station that I know of, which tells me that Bluetti believes in the EP500’s effectiveness over time.

What Does It Come With?

The standard EP500 and EP500Pro as a single unit come with the following:

  • AC charging cable
  • PV (solar) charging cable
  • Warranty card
  • User manual

The EP500Pro kit that I’m comparing comes with the following:

  • 2x EP500Pro power stations
  • 2x AC charging cables
  • 2x PV (solar) charging cables
  • 1x Split-phase fusion box
  • Warranty card
  • User manual

10.8kWh EcoFlow Delta Pro Kit – Overview

10.8kWh EcoFlow Delta Pro Setup
10.8kWh EcoFlow Delta Pro Setup (2x Delta Pros, 1x Extra Smart Battery, 1x Double Voltage Hub).

One of the main benefits coming from the Delta Pro is its ability to be used for RV use. Even with a kit like the one pictured above, each module has wheels and a telescoping handle to make it easier to transport.

With two Delta Pros connected to the Double Voltage Hub, you can power nearly any home appliance you may need at 240V. When connected in this way, the Delta Pros can achieve 7,200W of continuous power. To put that into perspective, the average electric oven uses about 3,000W and is one of the highest power consumers in a household.

A system with this output capability should also have a good amount of battery storage to be able to use power for long periods of time. With two Delta Pros and one Smart Battery, this setup has 10.8kWh of backup power available. This is a significant system in terms of size and capability. Plus, you can add more batteries if needed.

What Does It Come With?

Since this configuration that I’m comparing today is not found in a single kit, I combined multiple Delta Pro products into a kit. I’m showing the kit that I created from Shop Solar Kits because they had the lowest price compared to Amazon and Bluetti’s websites.

My kit combines the following packages:

  • 2x Delta Pro kit (link to kit)
  • 1x Delta Pro Extra Smart Battery (link)
  • 1x Double Voltage Hub (link)

In total, the combined products/packages come with the following:

  • 2x Delta Pro power stations
  • 1x Delta Pro Smart Extra Battery
  • 1x Double Voltage Hub
  • 2x AC charging cables
  • 2x car charging cables
  • 2x Solar charging cables
  • 2x DC5521 to DC5525 cables
  • 2x Handle covers
  • 2x Delta Pro to Smart Generator adapters
  • 2x User manuals
  • 1x Copy of Solar Generator Setup & Maintenance Guide
  • 2-Year warranty

This table shows a list of various devices/appliances along with their run times when used with the 10.2kWh Bluetti EP500Pro x2 with split-phase kit and the 10.8kWh EcoFlow Delta Pro x2 (with extra battery) configuration. NOTE: Estimates are my own calculations based on 1) 85% inverter efficiency for AC-powered devices/appliances, and 2) Discharge to 10% battery capacity (90% DoD).

With this much capability coming from both power station kits, you may want to take an inventory of your appliances and their power consumption. Older appliances tend to use more power than recent ones, so these times may vary.

I recommend using a simple energy consumption calculator like RapidTables to get an idea of your home or RV’s usage over time.

Which Is Better Overall?

The EP500Pro x2 with split-phase is the better option because it recharges faster from solar and has a higher battery cycle life. Its battery longevity provides the most value because it lasts nearly twice as long as the Delta Pro kit.

Conclusion: Which Company Produces Better Solar Generators?

EcoFlow vs. Bluetti logos

EcoFlow’s River series is better than Bluetti’s smaller power stations. However, Bluetti has better large solar generators due to their output port options, faster solar charging, better warranties, and higher quality batteries that last longer.
