Why Should You Buy AC500+B300S?

The AC500 is the biggest of Bluetti’s solar power stations. The brand has been hyping it up as the “apex” of its series. With a 5000-watt continuous inverter and storage expandability of up to 18,432Wh, this is going to be an enormous power backup system for both off-grid and household applications.
1. 100% Modular Power Station
The AC500 is a 100% modular power station from Bluetti and is the elder sibling to its 3000W variant, the AC300. With the help of supplementary battery modules, you can crank it up to a colossal 18432Wh of power, which is enough to run your household for around six days.
With a single unit of the additional battery pack (B300S), you get 3072Wh of capacity added to the unit. You can add up to six units of the battery modules to increase the storage capacity.
This modular profile gives you much freedom in simply achieving the required amount of backup you need for your home, worksite, and off-grid living spaces.
2. Wide Compatibility
The AC500 is designed to support the B300, the extra battery module of the AC300. It means the customers of the AC300 can just upgrade to the new system with 5000W AC output without reinvesting in batteries.
Fine, you can use up to four units of the B300 battery packs with the AC500, and more interestingly, you can also mix up the B300 and B300S battery packs to get higher storage capacities.
3. 3000W Solar Input
Bluetti AC500 supports a solar input of up to 3000 watts. With the maximum PV input, you will be able to charge it in just under two hours. You can use the brand’s D300S connector to charge it from a rooftop solar panel with an output between 3,000W~5,000W.
Why Should You Buy EcoFlow Delta Pro?

The Delta Pro is the flagship product of EcoFlow and the top-tier variant of its famous Delta series.
The 3600W solar power station comes with a built-in battery of 3.6kWh, and you can crank it up to a huge 25kWh using the brand’s smart battery packs and a gas generator.
Unlike SuperBase V and AC500, the EcoFlow product is highly portable and compact in design. You can easily take it on your trips and travels by seizing on its strong, built-in handles, thanks to its handy profile.
1. 3.6kWh to 25kWh Modular Machine
As said above, the Delta Pro equips a 3.6kWh LiFePO4 battery pack under the hood. It is expandable with the brand’s smart battery packs and a smart gas generator. That is how you can use it as an ideal home backup system to support your entire household on off-grid power.
2. Fast Charging Power Station
It is indeed one of the fastest-charging power stations on the market. You can charge it via six methods, including solar, AC power, and EV chargers. The multi-charge feature even allows you to combine multiple charging options to achieve a rate of up to 6500 watts.
3. EcoFlow Smart Gas Generator
Yet another incredible thing with the Delta Pro is that you can charge it from the brand’s innovative dual-fuel gas generator in an emergency.
The smart gas generator is a 1800W power source that works on both LGP and gas. Though not an eco-friendly choice, you can use it to charge your backup systems in emergencies.
Why Should You Buy Zendure SuperBase V?

The SuperBase V is a series of plug-and-play home backup systems from Zendure.
It is a massively expandable backup station that you can ideally use in your home, worksite, or off-grid living conditions for unlimited off-grid power. Zendure SuperBase V appears in two variants: V6400 and V4600. They respectively carry 6438Wh of semi-solid-state batteries and 4608Wh of LiFePO4 battery packs.
1. Highly Modular Power Stations
Both the variants of Zendure SuperBase V are also incredibly modular power stations. Different from the Bluetti AC500, the base units of the SuperBase V pack up inbuilt batteries.
As you can see, the SuperBase V6400 has a 6438Wh semi-solid-state battery, while its LFP version, the V4600, packs a 4608Wh LiFePO4 battery pack. You can add up to four units of their respective Satellite extra battery modules to expand their capacities to 32190Wh and 23040Wh respectively.
Is Semi-Solid-State Battery Worth It? There is some heated debate over the life cycles of a semi-solid-state battery that indeed has fewer charging cycles compared to LiFePO4. So you can think twice before investing in a unit of SuperBase V6400, but it seems its LFP version, V4600, is worth its cost. |
By pairing two pieces of the base units together, you can further double the storage capacities. That is how the SuperBase V series becomes some of the largest solar chargeable power backup systems in the world. They have a clear edge over the Bluetti and EcoFlow alternatives in terms of overall expandable storage capacities.
2. 120V/240V Dual Voltage Output
Yet another unique selling point of Zendure SuperBase V is the dual voltage output of 120V and 240V. This is a way you get a chance to enjoy 240V output on the road. You can choose between the power outputs using the respective outlets.
3. 6600W Fast Dual-Charging (3000W Solar Charging)
With the combination of AC input and a solar source, you can charge a SuperBase V at a speed of up to 5150 watts, and with an added extra battery, it can be 6600 watts. That means the Zendure is one of the fastest dual-charge power stations on the market.
The machine has a solar input of up to 3000 watts and it can be charged at a speed of 3600 watts with an EV charger. The brand itself has a 400W folding solar charger on sale, although it is compatible with third-party solar panels from 12V to 150V.
Hence, you can use it with your home’s existing solar system.
Final Thoughts
That has been our quick comparison of Bluetti AC500, EcoFlow Delta Pro, and Zendure SuperBase V.
We have covered some of the coolest features of the new solar home backup systems. The Zendure and Bluetti products are currently seeking crowdfunding on Kickstarter and Indiegogo. It is the right time to get the models at the best prices before the early bird deals run out.
Meanwhile, the EcoFlow Delta Pro has been on the market for more than a year. Launched in 2021, it is still one of the most prominent home-friendly portable power stations. You can expand the device up to 25kWh using the brand’s smart extra modules as well as a gas-based smart generator.
