Project Overview：

This integrated system combines photovoltaics (PV), energy storage (ESS), and the grid to maximize energy efficiency.

During sunlight, PV powers loads and charges ESS; at night or during low sunlight, ESS and PV jointly supply power until ESS SOC drops below 15%. The grid recharges ESS if SOC falls below 80%, ensuring reliable and cost-effective energy management.

System Configuration:

20 kWp PV

258 kWh Star Series Energy Storage Cabinet

Benefits：

Daylight powers loads, excess charges storage.

Low sunlight uses both solar and storage.

Grid supplements storage ＜ 80% SOC at night.
