Start at 3072Wh and scale up to 11kWh by adding extra batteries. Power that grows from a half-day backup to three full days of household use.
Choose which circuits stay powered via the app, so the fridge, Wi-Fi, or medical equipment run longest. Non-essential loads switch off automatically once capacity drops below your set threshold.
Reach 80% in just 75 minutes via 2300W AC, or pull up to 1600W from solar across dual ports. Five charging options in total, including generator and in-vehicle.
EV-grade full-tab LFP cells cut self-heating by 25%, delivering thousands of safe, stable cycles. Backed by a 5-year warranty.
Sub-10ms UPS protects critical gear, while operation under 25dB keeps things peaceful even under load.
