connecting with inverter;
3) Turn on circuit breaker “PV” (QF11), to connect the PV panel on the hybrid inverter;
4) Turn on circuit breaker “LOAD” (QF2), to connect the emergency load on the hybrid inverter.
4.2 System Interface
4.2.1 Main Operation Modes
When the system is connected with the public grid, the GHESS series solar battery hybrid system
has 2 operation modes: Self-use mode and Peaking Shaving mode. When outages, the system can
also operate under back up mode, in which the grid is disconnected and emergency load power is
supplied by the system independently.
Below is introduction on the 3 operation models:
1. When the grid is normal:
1) Self-use mode: the GHESS series solar battery hybrid system can increase the PV Self-use up
to 75%
Daytime: If there is enough sunshine, energy generated by PV supplies the load first and then
charges battery packs; if the load power is covered and battery is full charged, surplus energy
will be fed into the public grid to win the FIT tariff;
Night or no enough sunshine : the hybrid system first discharges the battery pack to cover the
load; if the energy is still not sufficient, the grid will power the rest family load.
Note: The system has finished initial setting and configuration before leaving factory. So during the
installation and operation process, it is not suggested for installer/customer to change the default
settings and internal wiring, as this will void the warranty. If there are any special requirements
needed, please contact your seller for support.
