SAJ B2 Series Low-Voltage B2-5.0-LV1 5kWh LiFePO4 Battery Designed For Residential/Commercial Solar Energy Storage Solutions
B2 Low-Voltage Solar Energy Storage Battery Revolutionize Energy Storage Solutions
B2 LV series is a low-voltage cobalt free LiFePO4 battery. With a sheet metal shell, it adapts a structure compatible with wall-mounting and stacking installation methods. The pack of B2 batteries contains battery modules and a BMS controller. The number of battery modules can be flexibly matched according to the user’s power demand, and up to 5 modules can be connected (25.0kWh).
SAJ B2 LV1 low-voltage solar LiFePO4 battery. With a compact and modern design, it is an expandable modular battery that is easy to install. This battery series is compatible with SAJ H1 and H2 inverters and can store from 5kWh to 40kWh (depending on the number of connected modules).
These are some of its advantages:
- This lithium battery allows for floor or wall mounting.
- Firmware can be updated remotely
