Description
The unit measures 660 × 650 × 575 mm and weighs 168 kg; two units can be stacked on top of each other to save floor area. The IP20 enclosure is intended for indoor use only. For short periods the battery delivers 375 A for 5 s. Up to 64 units are connected in parallel, and the total capacity reaches 983 kWh. The BMU control port is used to manage the units and to communicate with the system. The cells are LiFePO4, and the certificates are IEC 62619, CE, CEC and UN 38.3. The battery works with 48 V low-voltage inverters in household and commercial systems that need a large energy reserve in one enclosure.
How to choose
The LVL makes sense where a lot of energy at 48 V is needed with a minimum number of connections. Capacity is counted in units of 15.36 kWh, and the system current grows with the number of parallel units. For a high-voltage hybrid inverter the HVM is better, where a tower gives up to 22.1 kWh, or the HVL with 4 kWh modules for the USA.
