BLUETTI 2×EP800 + 6×B500
Two EP800s with six B500s is one of the largest things we list: thirty kilowatt-hours, nearly half a ton, parked rather than placed. A van day takes a fifth of it, which is not a van but a street. Two head-to-heads, both lost to other BLUETTI stacks. No owner has written in; the forums debate price and lock-in.

01 · Six real-world jobs
What the 2×EP800 + 6×B500 actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the 2×EP800 + 6×B500 if…
The buyer who needs 29,760Wh at the lowest cost of entry and gets it at $0.81 per nameplate watt-hour, provided you have made peace with no published warranty term and a slower 20ms transfer.
Decided 2 matchups · read one →
The off-grid or extended-outage buyer whose house runs entirely off the battery for days at a stretch. This is the only one of the two with 29,760Wh, and if your worst case actually drains a 19,840Wh bank, the extra 9,920Wh is the whole reason to buy, and at $0.81 per nameplate watt-hour it is the cheaper way to get there.
The buyer installing this as standby insurance that will rarely cycle. If the system spends most of the year at rest waiting for an outage, you never approach the 3,500-cycle limit, and the $3,598 you save is money the EP900's longevity was never going to earn back for you.
A rival won when…
The buyer who might grow later. Start here, add two B500 modules when you need them, and you land on a system that matches the EP800's capacity and, on this platform, beats it on output.
Decided 2 matchups · read one →
Almost everyone doing whole-home backup on a grid-tied house. 19,840Wh covers every standard outage with room to spare, and you get it for $3,402 less, at 6,000 cycles, with a 10-year warranty and a 10ms transfer, the same 15,200W the EP800 runs, minus the capacity you were not going to use.
Anyone cycling this daily: solar self-consumption, off-grid, or a home that leans on the battery year-round. The 6,000-cycle rating is where your money is, and at daily use it is the difference between roughly 9.6 and 16.4 years before the bank is spent.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

Owner reports are paraphrased from public YouTube comments and each links to its source; reviewer consensus is counted from cited excerpts, never quoted; our own verdicts are quoted. Specs on this page never come from any of them.
Reviewer consensus
1/7 positive excerpts, 1 sources
Prospective buyers on DIY/solar forums consistently cite the EP800's price premium as the main barrier, even while acknowledging it's a strong product — a bigger spend still in a dual-inverter whole-home build.

From the test desk
“Buy the 2xEP900 + 4xB500 unless you genuinely need more than 19,840Wh of storage.”
“Buy the 2xEP900 stack unless this system will mostly sit idle as rare-use backup.”
