Description
A 3.5kWh LiFePO4 lithium battery module in a standard 19″ rackmount chassis, built to pair with 48V hybrid inverter systems. Modules stack and parallel as your storage needs grow — up to 56kWh in a single bank.
Lithium gives you far more usable capacity than an equivalent lead-acid or GEL bank, and a working life measured in years rather than months: 6,000 charge cycles at 80% depth of discharge. The module carries its own battery management system with CAN and RS485 communications, so a compatible inverter can read its state directly.
Key Features
- LiFePO4 chemistry — safer and longer-lived than standard lithium-ion
- 6,000 cycles at 80% depth of discharge
- 74Ah / 3.5kWh usable storage at 48V
- Stackable and parallelable to 56kWh total
- 19″ rackmount chassis with carry handles
- Integrated BMS with CAN / RS485 communications
- Natural cooling — no fan noise
- Wide operating range: −20°C to +50°C
- 5-year carry-in warranty
