Goodrive100-PV Series Solar Pump Inverter

Q1: Keypad display AL-S, and system stop running?

A: AL-S is weak light alarm, means the current sunshine is not enough to drive the pump, result in the running frequency Hz is less than lower limit: (lower limit: P15.05*P00.03)

Conditions of AL-S:

a. Running frequency is less than P15.05*P00.35, and keep more than P15.20 time.

b. Current PV output voltage(P18.01) is less than undervoltage point. (P15.37)

If current condition meets a or b, keypad will display AL-S alarm.

If P15.32=0, the system will switch to AC power input channel.

Q2：Single phase pump cannot start?

A. If the model is -SS2? Only this model supports driving single phase pump.

B. There are 2 ways for single phase pump：

1. Connect pump L&N to inverter U&W.

2. If the first way cannot start, Please remove the capacitors as the following photo, and make sure the resistor value U&V is the biggest OHM, U&W is the smallest value.

Note: after remove the capacitor, must connect S4 & COM terminals on control board.
