Page 39: System Operation
System Operation System Operation 5.1 Inverter Working Mode The inverter supports several different working modes. 5.1.1 Self Used Mode Go to the "Hybrid work mode" menu, and select the "Self used mode". Under Self Used mode, the priority of PV energy consumption will be Load > Battery > Grid, that means the energy produced by PV gives priority to powering local loads, the excess energy is used to charge the battery and the remaining energy is fed into the grid.
Page 40 System Operation BACKUP is the sequence of load consumption. 1 2 3 c) No PV Input The inverter will first discharge the battery energy for home load consuming when no PV input( such as in the evening or some cloudy or rainy days). If the demand is not met, the loads will consume grid energy.
Page 41 System Operation a) Wealthy PV Energy When PV energy is wealthy, the PV energy will be first consumed by loads. If there is excess PV power, the power will be fed into grid. If there is still PV energy left after load consuming and grid feeding, then the remaining PV power will be used to charge the battery.
Page 42 System Operation c) No PV Input The inverter will first discharge the battery energy for home load consuming when no PV input (such as in the evening or some cloudy or rainy days). If the demand is not met, the loads will consume the grid energy.
Page 43 System Operation 5.1.3 Back-up Mode Go to the "Hybrid work mode" menu, and select the "Back-up Mode". Under this mode, the priority of PV energy consumption will be Battery > Load > Grid. This mode aims at charging the battery quickly, and at the same time, you can choose whether to allow AC to charge the battery.
Page 44 System Operation Allow AC charging In this situation, the battery can be charged both with PV and AC. a) Wealthy PV power When PV energy is wealthy, PV charges the battery first, then meets the loads, and the rest is fed into the grid.
Page 45 System Operation 5.1.4 Off Grid Mode When the power grid is cut off, the system automatically switches to Off Grid mode. Under off-grid mode, only critical loads are supplied to ensure that important loads continue to work without power failure. Under this mode, the inverter can’t work without the battery.
Page 46 System Operation b) Limited PV power When PV energy is limited, BACKUP loads are first powered by PV and then supplemented by battery. BACKUP is the sequence of BACKUP load consumption. Under this mode, please complete the output voltage and frequency settings.
