This is how you add serious runway to an F3800 without buying a second unit. The BP3800 Expansion Battery adds another 3,840Wh of LFP capacity, built specifically to plug into the SOLIX F3800 and extend how long it can carry a home during an outage. Seamless expansion means it's designed to work with the F3800 you already have, not a separate system to configure.
It's built for the long haul: rated for 3,000 life cycles and a 10-year lifespan, backed by a 5-year hassle-free warranty.
In the box: the BP3800 Expansion Battery, a battery-to-host cable, and important information/documentation.
