Operation mode description of 1-phase residential
storage inverter
Applicable to: SHxxRS series
1Production for self-consumption
The inverter is set to the mode of production for self-consumption, and the control
supplies power to the load first (including the backup port load).
1.1 Daytime PV power ≥ load power
As shown in Figure 3-3 below, when the battery SOC is lower than 100%, after
the PV input power meets the load power supply, the remaining energy
charges the battery and still delivers the remaining energy to the power grid.
When the battery SOC is 100%, after the PV input power meets the load power
supply, the surplus electric energy is transmitted to the power grid.

1.2 Daytime PV power < load power
As shown in figure below, when the battery is fully charged, the battery
discharges to the load, and the insufficient part is supplied by the power grid.
When the battery power is insufficient, the load consumption is supplemented
by the power grid.
Daytime PV power < load power
1.3 No-light scenario at night
Under no-light scenario at night, PV power is 0. As shown in figure below, when
the battery is fully charged, the battery discharges to the load first. If the
battery discharge cannot meet the load consumption or the battery power is
insufficient, the required electric energy is provided by the power grid.
