Why we like it.
Big power for a home

Very long cycle life
6,500-plus cycles to 80% with EV-grade LiFePO4 and a 5-year warranty.
Expandable

Flexible charging
AC, solar (2,000W MPPT), car, or AC plus solar; the US version reaches 100% in about 1.8 hours.
A few things to consider.
Heavy and large
A 3,840Wh station is a staged-in-place unit, not a carry-to-camp pack.
Expansion batteries are extra
The 11.52kWh figure requires two additional FB3840 batteries.
Solar ships separately
Combination purchases arrive in separate shipments.
