  • Page 19: Operation Modes

    3.4 Operation Modes Wattsonic 4.0~20.0kW-3P series inverter has the following basic operation modes and you can configure the operation mode as per your preference in the App. General Mode Loads In this working mode, when the power from the PV array is sufficient, PV power will supply the loads, battery, and grid in the order of ...
  • Page 20 Peak load Shifting (Load Shifting) Loads Set the maximum power Pmax (kVA) contracted with the grid. When the load consumption is less than the Pmax, the PV will charge the battery first, and the grid supplies the load. When the battery is full, PV will supply the load together with the grid, but the battery doesn't.
  • Page 21 UPS Mode Loads In this working mode, the inverter will use the power from PV or grid to charge the battery until it is fully charged, and as long as the grid is there, the battery won’t discharge. Grid Back-up Loads When the grid fails, power from PV and battery will supply loads connected on the back-up side (UPS).
  • Page 22 Economic Mode Loads In this working mode, you can set charge/dis- charge power and time in the App, inverter will use the power from PV or grid (whether to use can be set in the App) to charge the battery in the predetermined period.
  • Page 23 Off-grid Mode Back-up Loads In the purely off-grid mode, power from PV will supply the back-up loads first and then charge the battery if there's surplus power. No Grid Back-up Load When the power from PV isn’t enough, the battery will discharge to supply back-up loads together with PV.
