Wait for approximately 1 minute.
Solar king inverter relay failure.
Turn off the pv array dc isolator located at the inverter.
If this is a permanent fault the inverter requires replacement.
Turn on the pv.
Turn on the solar supply main switch and the ac isolator if installed.
Is your solar king solar inverter showing a relay failure message on the screen.
The fault light is on.
If so find out what it means and what you can do about it here with gold coast solar power solutions.
Follow the shut down procedure below.
The screen is showing relay failure.
Additionally you may hear a clicking from the inverter as the relays inside the unit trying to pull in.
We recommend a health check to eliminate an external cause for this fault prior to purchasing a new inverter.
A solar king solar inverter relay failure message occurs when an internal relay inside the inverter fails to operate correctly.
There are two signs that you have this issue.
Assuming the inverter is accurate in diagnosis then ideally a relay replacement would be the simplest cheapest solution.
Error code 120 when a growatt solar inverter displays the error code 120 it means that there is a problem with the current sensor.
An error code 117 on a growatt solar inverter means that there is a problem in the relay circuit.
This fault can pertain to water ingress or panel related earth faults.
Turn off the solar supply main switch or inverter ac isolator if installed.
