  • Page 38: Working Mode

    ORKING MODE The inverter supports several different working modes, described below. 1) Self-used mode Under self-used mode, the priority of PV energy will be Load > Battery > Grid, that means the energy produced by PV gives priority to local loads, excess energy is used for charging the battery, and the remaining energy is fed into the grid. This is the default mode to increase self-consumption rate.
  • Page 39 No PV power When there is no PV power from the strings, the inverter will first discharge the battery energy to power the loads. If the demand is not met, then it will consume power from the grid. 2) Feed-in Priority mode Under feed-in priority mode, the priority of PV energy will be Load >...
  • Page 40 Limited PV Energy When PV energy is limited and cannot meet the feed-in grid power, the battery will discharge to meet it. No PV input When there is no PV input, the inverter will first discharge the battery energy for powering the loads. If the demand is not met then the inverter will draw power from the grid.
  • Page 41 3) Time-based control mode Under this mode, the user can control the charging and discharging of the inverter. The following parameters can be set: • Charge and discharge frequency: one time or daily • Charging start time: 0 to 24 hours •...
  • Page 42 Allow AC charging Wealthy PV power When PV energy is wealthy, PV charges the battery first, then meets the load and if there is any excess energy it will be fed into the grid. Limited PV power When the PV energy is not enough to charge the battery, the grid energy will charge the battery as supplement. Meanwhile, the loads are powered from the grid energy.
  • Page 43 5) Off Grid mode Under this 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. This mode is automatically enabled when the inverter detects an AC grid malfunction and the EPS output is enabled in the App.
