Inverter Working Mode
The inverter supports several different working modes.
5.1.1
Self Used Mode
Go to the "Hybrid work mode" menu, and select the "Self used mode".
Under Self Used mode, the priority of PV energy consumption will be Load > Battery > Grid, that
means the energy produced by PV gives priority to powering local loads, the excess energy is used to
charge the battery and the remaining energy is fed into the grid.
This is the default mode to increase self-consumption rate. There are several situations of self-used
working mode based on PV energy.
a)
Wealthy PV Energy
When PV energy is wealthy, the PV energy will be first consumed by loads, the excess energy
will be used to charge the battery and then the remaining energy will be fed into the grid.
b)
Limited PV Energy
When the PV energy is not enough to cover all consumption, the PV energy will be entirely used by loads,
and the insufficient part will be supplied by battery. Then still insufficient parts will be supplied by grid.
