The Growatt ALP LV Battery System is a modular low-voltage battery designed for homes and businesses wanting to store excess solar for use at night. Starting at 5 kWh per module, the system expands up to 40 kWh per cluster by stacking additional modules in parallel — letting you start with what you need and add capacity as your energy use grows.
Built on cobalt-free Lithium Iron Phosphate (LFP) chemistry, the Growatt ALP LV Battery System uses a 51.2V nominal voltage with 92% depth of discharge, meaning you can use almost the full capacity in practice. The system pairs with Growatt SPH hybrid and SPF off-grid inverters via CAN communication, and includes an integrated BMS for voltage, temperature, and cell balancing protection.
The Growatt ALP LV Battery System is suited to homes expanding an existing solar setup or businesses wanting scalable storage. Its IP66 rating means it can be installed indoors or outdoors, and the modular design allows capacity to grow in 5 kWh steps without replacing the system.
