    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 35 System Operation BACKUP Smart load Normal load 1 2 3 is the sequence of loads consumption. 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 36 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 37 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 38 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 39 System Operation Allow AC charging In this situation, the battery can be charged both with PV and AC. a) Wealthy PV energy When PV energy is wealthy, PV charges the battery first, then meets the loads, and the rest is fed into the grid.
