3.3 Working Mode • Day: - When the power generated in the PV system is 3.3.1 System working mode sufficient, the inverter supplies electricity to the household load as first priority as priority. The excess Economic mode power will then charge the batteries first, and still remaining power will be fed back into the grid. - Page 8 Back-up mode 3.3.2 Inverter operation mode NOTICE Waiting mode Off-grid mode • Back-up mode: This mode is used when the grid is unstable and there is an important load. The inverter supplies power to the load in off-grid mode when the grid is disconnected , and Self-check mode switches to on-grid mode when the grid is restored.
