Self consumption mode
• For solar power, consider self consumption mode in priority: the excess power charges the
battery in day time; the battery supplies power to the load when there is no solar power
generated at night. This will improve the self consumption rate and saves electricity costs.
• It is suitable for areas with high electricity prices and little or no solar power generation
subsidies.
• When the power generated in the PV system is sufficient, the inverter will supply electricity to
the household load as first priority. The excess power will then charge the batteries first, and
still remaining power will be fed back into the grid.
• When the power generated in the PV system is insufficient, the battery will supply electricity
to the household load first. If the battery power is insufficient, then the load will be powered
by the grid.
• When the battery cannot supply power, the PV system will supply the loads in priority. If the
PV power is insufficient, then the loads will be powered by the grid.
• If neither the PV system nor the battery could supply power, the grid would supply power to
the loads and form BYPASS output.
• When the grid is disconnected and the backup function is disabled, the power generated in
the PV system will supply the loads in priority, and the excess power will charge the batteries.
