On-grid Port to Retrofit the Existing PV System
figure 2-9 On-grid Port to Retrofit the Existing PV System
The AC terminal of the PV inverter and the GRID terminal of the hybrid inverter are con-
nected in parallel.
Backup terminal to Retrofit the Existing PV System
figure 2-10 Backup terminal to Retrofit the Existing PV System
The backup terminal retrofits the existing PV system in order to maximize the use of PV en-
ergy by allowing the PV inverter to work even when off-grid.
The AC terminal of the PV inverter and the BACK-UP terminal of the hybrid inverter are con-
nected in parallel. This option is not available in the European region.
The PV inverter power cannot exceed the nominal power of the hybrid inverter (if it is a sin-
gle-phase PV inverter, the PV inverter power cannot exceed the single-phase nominal power
of the three-phase hybrid inverter).
Before retrofitting the existing PV system to an backup terminal, the "Frequency Shift Power
Control" parameter needs to be enabled. For details, please refer to "8.12.15 Frequency
Shift Power Control".
