Page 37: System Operation
System Operation System Operation 5.1 Inverter Working Mode The inverter supports several different working modes. 5.1.1 Self-consumption Mode Go to the "Hybrid Setting" menu, and select the "Self-consumption mode". Under Self-consumption 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 38 System Operation BACKUP Smart load Normal load is the sequence of loads 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 39 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 40 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 41 System Operation 5.1.3 Back-up Mode Go to the "Hybrid Setting" 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 42 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 43 System Operation 5.1.4 Forced Charge/Discharge Function According to the demands of application, the user can set the inverter to work on forced charge/discharge the battery in any working mode. There are three time periods in which you can set this function. Outside of the set periods, the inverter returns to its original working mode.
Page 44 System Operation a) Wealthy PV power When PV energy is wealthy, the PV power will be first consumed by critical load, then charge the battery. BACKUP Smart load Normal load is the sequence of PV energy transmission. b) Limited PV power When PV energy is limited, BACKUP loads are first powered by PV and then supplemented by battery.
