Working Principle Video of 375kW/723kWh Three-Parallel Commercial & Industrial PV-ESS System
468 pieces of 650W PV modules convert solar energy into direct current, which is fed into three 125kW three-phase hybrid grid inverters paired with three 241kWh energy storage cabinets. Interfaced with the utility grid and factory loads, the system prioritizes photovoltaic power for load consumption. Surplus power is stored in energy storage units and discharged during peak electricity demand to realize peak shaving and valley filling, ensuring stable power supply for the factory.

Working Principle of 3.5kW/5kWh PV Energy Storage System
This 3.5kW off-grid PV energy storage system uses five 620W solar panels to generate direct current. Electricity first supplies household loads such as lighting, TV, fans and refrigerators directly. Excess power charges the 5kWh wall-mounted battery. At night, the battery discharges for domestic use, while the municipal grid serves as backup power to avoid blackouts.

Working Principle Video of 8.5kW & 16kWh PV System
This 8.5kW photovoltaic energy storage system connects two photovoltaic strings to the inverter. After solar energy is converted into direct current, part of it directly supplies power to household loads, and surplus electricity is stored in the 16kWh wheeled lithium battery. The battery discharges to supply power at night, with municipal electricity serving as backup. The system automatically switches to off-grid mode during power outages to realize self-consumption and emergency power supply.
