15.36kWh rated energy – ideal for whole-home backup and high-consumption households.
51.2V system voltage – reduces current draw, improving efficiency and compatibility with hybrid inverters.
Built-in wheels – uniquely solves installation challenges for heavy batteries (100kg).
Compact dimensions (825×413×235mm) – fits garages, basements, or utility rooms.
150A max charge/discharge current (7.68kW continuous power).
Wide voltage range (43.2V–58.4V) – stable performance under heavy loads.
>6,000 cycles (at 0.2C, 25°C) – industry-leading lifespan.
>10-year design life – low lifetime cost of ownership.
LiFePO₄ chemistry – intrinsic safety (thermal/chemical stability).
Touchscreen interface – real-time monitoring and control.
Remote management – monitor "from anywhere" (app/web integration implied).
Built-in BMS safeguards against overcharge/discharge, short-circuit, and temperature extremes.
North America
USA/Canada: High demand for whole-home backup (hurricanes, wildfires, grid failures); wheeled design simplifies garage/basement installation.
Europe
Germany/UK/Nordics: Rising electricity costs; cold climate support (-20°C discharging); wheels aid placement in cellars/utility rooms.
Off-Grid & Rural Areas
Australia (farms/ranches), Africa, Latin America: High capacity sustains off-grid living; mobility benefits remote installations.
Homeowners needing extended backup (e.g., multi-day outages).
High-energy users (EV owners, large families, workshops).
Off-grid enthusiasts (cabins, rural properties).
Elderly/accessibility-focused users – wheels reduce installer dependency.
Disaster-Prone Regions
Japan (earthquakes), Philippines (typhoons): Critical backup for emergencies; wheels enable quick relocation.
Markets with Space Constraints
Urban homes (townhouses, apartments): Wheeled mobility avoids permanent wall/floor space commitment.
