5/10 YearsTo enhance the power efficiency of residential electricity consumption, we are thrilled to introduce the WALV series battery
UIENERGIES WALV-5K 100Ah 51.2V 5kWh Low Voltage Residential LiFePO4 Battery Energy Storage System
WALV residential battery energy storage system with IP65 protection, Operates in temperatures from 0 to 55℃, suitable for diverse environments. The WALV series not only stores excess electricity generated by photovoltaic systems during the day for use at night or on cloudy days but also utilizes peak and off-peak electricity price differences for charging and discharging, reducing household electricity costs. In addition, the WALV lithium iron phosphate household energy storage battery can be used as an emergency backup power supply for the family. When the external power grid fails or the power fails, it can provide a stable power supply for the important loads of the family and avoid losses or dangers caused by power outages.
