BLUETTI AC500 + 2×B300K
The AC500 with two B300Ks is five kilowatts of inverter on five and a half kilowatt-hours, so it starts anything in the house and lasts an hour doing so. Every scene we run clears; four wins in 11 head-to-heads. No owner has written in; reviewers report units arriving with a dead inverter or a missing cable.

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 AC500 + 2×B300K if…
You want the built-in port array without shopping for an add-on hub to fill it out.

You want to save $1,000 up front, or you rent and can't hardwire a combiner box.
Decided 2 matchups · read one →
You're starting a central AC, a well pump, or a big motor load — the 10,000W surge and 5,000W continuous clear what the Apex's 7,680W might stall on.

The unit stays put — a basement or utility-room backup where 62 lb never has to move.

A rival won when…
You want the safety net — a 5-year warranty, 4,000 cycles, and retail return protection from Costco or Amazon.
Decided 7 matchups · read one →
Your loads stay under 2,000W and always will — the EP500's ceiling is comfortably above a fridge, lights, and electronics.

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.

From the test desk
“This is close, and it splits cleanly by use case.”
“The SOLIX E10 is the more capable unit on nearly every axis that isn't the sticker: 6,144Wh to the AC500 stack's 5,530, a 9,000W solar ceiling against 3,000, a 5-year warranty where the stack lists none, 4,000 cycles to…”
“Buy the Anker F3800 Plus unless you have a specific, capacity-hungry reason not to.”
