Goodrive100-PV Series Solar Pump Inverter
Appendix C Power frequency & PV switching solution
C.1 Solution introduction
Generally, inverters do not allow simultaneous connection of power frequency and PV. If such
simultaneous connection is required, switching control circuit needs to be configured externally.
The following figure shows a solution for reference.

Questions and answers
I want to connect a low water level sensor to GD100-PV invt how it supposed to do
The low water level sensor should be connected to the INVT Goodrive100-PV Series inverter at the designated terminal. Based on the standard wiring diagram:
1. Identify the low water level switch terminals.
2. Connect the common terminal of the sensor to the COM terminal on the inverter.
3. Connect the sensor output to the appropriate input terminal (e.g., S1 or S4) on the inverter.
4. Ensure wiring is secure and correctly configured according to the installation guidelines.
This setup allows the inverter to receive signals from the low water level sensor and respond accordingly.
