• GFDI Fault
1.If panels is PV- grounded, please check the impedance between the earth
and the PV-,
the impedance must be
less than
100
Ω
2.
.If panels is PV+ grounded, please check the impedance between the earth
and the PV+,
the impedance must be
less than
100
Ω
3.The type Fuse of GFDI is DC 1000V/500mA
4. If the problem persists please call service.
• No Utility
1. Grid is not connected.
2. Check grid connection cables.
3. Check grid usability.
12. INVERTER FAILURE
• PV Over Voltage
1. Check the open PV voltage, see if it is greater than or too close to 600Vdc for
Growatt 1500 HF,Growatt 2000 HF and Growatt 3000 HF.
2. If PV voltage is less than 600Vdc for Growatt 1500 HF ,Growatt 2000 HF and
Growatt 3000 HF, and the problem still occurs, please call local service.
•
Consistent Fault
1. Disconnect PV (+) or PV (-) from the input, restart the PV-Inverter.
2. If it does not work, call service.
> If there is no display on the panel, please check PV-input connections. If the
voltage is higher than 150V, call your local service.
> During periods of little or no sunlight, the PV-Inverter may continuously start
up and shut down. This is due to insufficient power generated to operate the
control circuits.
