Work Priority & Mechanism

1.When the grid is normal:

  • Daytime: If there is enough sunshine,energy generated by PV supplies the load first and then charges battery packs, if the load power is covered and battery is full charged, surplus energy will be fed into the public grid to win the FIT tariff.

  • Night or no enough sunshine: the hybrid system first discharge the battery pack to cover the load, if the energy is still not sufficient, the grid will power the rest family load.

2.When the grid is failed or abnormal 

  • Auto-switch to off grid: it has device has integrated backup function. So when the device sensors the drop / change of the grid voltage, it disconnects the relay completely and then shifts from on-grid to off-grid mode. Under the off-grid mode, the important load is powered by battery.

  • Auto-switch to on grid: When the device sensors that the grid is back to normal,it stops running under off-grid mode and then closes it's internal relay. The system is running under on-grid mode again.
