03 Product Introduction
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.
• Day time:
• When the power generated in the PV system is sufficient, it will supply the loads in priority.
And the excess power will charge the batteries first. The remaining power will be sold to
the grid.
• When the power generated in the PV system is insufficient or no power is generated, the
battery will supply the loads in priority. If the battery power is insufficient, then the load
will be powered by the grid.
• Night:
If the battery power is sufficient, the load will be powered by the battery. If the battery power
is not enough, the load will be powered by the grid.
