Maximum Solar Utilization Thanks to Smart Battery Storage

A PV system only operates truly efficiently when excess solar energy is stored rather than fed into the grid unused. Battery storage is the key component for using your solar power as needed and at a later time.

 

How it works in residential and small-business settings

The direct current (DC) from the modules is converted by the inverter into usable alternating current (AC). The inverter charges the battery with energy that isn’t immediately needed in the home or business. When PV production decreases—for example, in the evening hours—the system automatically feeds the stored energy back into your home’s or business’s electrical grid.

Perfect System Integration

Modern Huawei storage systems communicate with the inverter and the connected energy management system every second. This ensures that self-consumption of electricity is continuously optimized. Consumption peaks can be efficiently smoothed out, and thanks to the integrated emergency power function, your building remains reliably powered even in the event of a public grid outage.
