Solid-State Battery
Higher energy density and no flammable liquid electrolyte means more power in a smaller, safer package than traditional lithium-ion batteries.
4000W / 2611Wh
Rated for 4,000 watts with peak power of 6,000, the B4000 SST can run household appliances, desktop PCs, power tools, and more. And with 2,611 watt-hours of capacity, it’s the perfect backup power solution for your home during a blackout.
Fast Charging
Even with its extreme capacity, the B4000 SST fast-charges up to 80% in just over an hour and 100% within 1.5 hours using AC input. Using the 12V vehicle adapter, a full charge takes 12 hours, while charging with 600W solar power from optional Yoshino solar panels takes just 5.5 hours.
