will be stored in the battery modules (E). The storage system's
inverter (F) converts the AC power to DC power while the
battery modules (E) are charging.
When the production is lower than the consumption, electric
power will be released from the battery modules. The storage
system's inverter (F) converts the DC power of the battery
modules (E) to AC power. The utility's power meter (G),
measures the power supply and the power fed back to the grid (if
applicable).
Backup mode
In backup mode, the house is powered by the energy stored in
the battery modules and generated by the PV array. During that
time, the power from the PV array powers the house or charges
the battery modules, depending on production and consumption
levels. The storage system can also turn the PV array off if the
battery modules become fully charged.
