High Quality Solar Storage Powerwall

There are three modes of operation:

1.Photovoltaic Energy Storage and Residual Power Feed-In: When there is sufficient sunlight, part of the electricity generated by the solar array is used to meet the household's electricity needs, while the rest is stored in the battery bank. Any excess power beyond this is delivered to the public grid through a grid-connected inverter.

2.Photovoltaic Energy Storage and Partial Power Supply: In this mode, the electricity generated by the solar array first meets the household's electricity demand, and any excess is stored in the battery bank. If the battery bank is full, additional excess power can be delivered to the public grid.

3.Photovoltaic Energy Storage Only: Here, the electricity generated by the solar array is primarily used to meet household electricity needs and is stored in the battery bank. No excess power is delivered to the public grid.
