Pure Sine Wave Off Grid Energy Storage MPPT Solar Charge Controller Inverter Ground Power Unit DC/AC Converter
PV Self-consumption: Energy generated by PV panels will be firstly used for local load, the remaining energy used to charge batteries, and the rest power fed to the grid.
Battery Support: When no PV is available, the energy stored in the battery will support the local load first. When battery energy is insufficient, the grid will supply power to the load simultaneously.
Back-up Mode: When the grid fails, the system automatically switches to back-up mode. The back-up load can be supported by both PV and battery power.
Grid Charging: The grid can charge the battery. Charging times and power levels are fully adjustable.
Key Product Advantages
The battery charge and discharge current up to 120A.
Off-grid peak power can reach twice of rated power (15S).
High control precision in Self-use mode.
Battery side high frequency transformer isolation, safe and reliable.
Rapid 10ms switching time.
