For BMS protection features and inverter compatibility, see the next section.
The built-in Smart BMS monitors temperature, current, voltage, SoC, and SoH in real time. This keeps the 48V backup power system operating safely under all load and environmental conditions.
BMS Protection — 9 Layers:
Over-charge protection
Over-discharge protection
Over-current protection
Over-voltage protection
Overload protection
Short circuit protection
High and low temperature protection
Cell balancing system
SoC and SoH continuous tracking
The BMS battery management system self-optimizes continuously, extending service life without manual intervention.
Compatible with 99% of Inverter Brands:
Deye, Growatt, Victron Energy, SMA, Solax Power, GoodWe, Schneider Electric, SOFAR, Megarevo, Luxpowertek, SRNE, ATESS, Hypontech, EPEVER, MUST, Voltronic Power, and more.
Communication runs over RS485, CAN, RS232, and Bluetooth — matching the protocol requirements of these brands out of the box.
The 48V backup power system delivers 5000+ cycles at 80% DoD in home energy storage battery deployments. Select configurations reach 8000 cycles and a 10-year design life.
Key performance metrics:
Low self-discharge — Holds capacity for up to 6 months in storage without maintenance charging.
High-current stability — High flat-voltage discharge and low internal resistance maintain output under heavy loads.
100% depth of discharge — Every rated kWh remains available, unlike lead-acid units that limit usable capacity to 70%.
2x power output — High discharge rate delivers twice the power of an equivalent lead-acid unit, with more than 95% energy capacity maintained.
Fast charge efficiency — Superior charge/discharge efficiency reduces system downtime between charge cycles.
Graphene heat dissipation — Manages thermal buildup during high-rate discharge without increasing noise.
The Smart BMS drives these cycle results by continuously balancing cells and preventing overuse conditions.
