Heres how the Bluetti EP900 and Panasonic Evervolt stack up against each other.
Both the EP900 and the Evervolt have very similar designs, too.
Modular batteries allow you to start small and upgrade your systems capacity as your energy needs change.
This way you wont need to buy another giant battery.
you might install up to four modules per system.
Panasonic allows you to install up to four Evervolt systems for a total capacity of 72 kWh.
Bluetti allows up to two EP900 systems for a total capacity of 36 kWh.
But the EP900s continuous 9 kW output gives it a big advantage over the Evervolt.
Your batterys continuouspower outputis the amount of power your battery can supply to your home at any given moment.
The higher the output, the more parts of your home the battery can supply power to.
The depth of discharge for each battery is the same (90%).
Draining your battery completely can actually shorten its lifespan.
And lastly, theres round-trip efficiency.
Think of it as a measure of howefficientyour battery system is at storing energy.
Panasonics Evervolt has better efficiency specs, no matter how you choose towire it up.
It has a round-trip efficiency rating of 89% when AC-coupled and 94% when DC-coupled.
The EP900 has one of the lower round-trip efficiency ratings weve seen for home batteries (85%).
The average round-trip efficiency rating for home batteries is around 90%.
That doesnt necessarily mean its bad – its just average.
Bluetii also promises a higher end-of-warranty capacity guarantee.
However, Panasonic offers a more robust warranty for its system.
Labor costs are also included.
Every home is different, and your battery system needs to be tailored to your homes specific energy needs.
We werent able to get an accurate estimate for how much the Panasonic Evervolt costs.
However, we can provide a ballpark estimate based on home battery pricing trends.
Most home batteries typically tend to cost around the $10,000 to $15,000 range.
But its definitely possible to find smaller batteries cheaper than $10,000.
Installation fees vary, but generally expect to pay somewhere between $2,000 to $3,000.
Bluetti does things a bit differently.
Because the Bluetti EP900 ships direct-to-consumer, the price for the system is listed on Bluettis website.
The price tag depends on the amount of energy storage capacity you want.
Which home battery is better?
First off, its important to note that theres no such thing as the best home battery.
The best home battery for you is the one that meets your households energy needs, goals and budget.
But with that being said, some batteries do offer better specs than others.
Youd just need to hire an electrician to help you implement the sub-panel.

You also wont have to worry about installing anything on your own – itll be left to the professionals.
This list also assumes you’re purchasing a battery for the main purpose of using it for energy backup.
First, we determined which categories would be used to evaluate each battery’s performance, capacity and value.
We also weighted each category.
The weight of each category reflects the importance we felt was relevant to the average consumer.
