Solar power protection plug trips when it rains
The rain itself won't stop them generating energy - the corresponding cloud cover that comes with rain will reduce the output of your system, but the effect is no more than a cloudy day with no sun.
FAQs about Solar power protection plug trips when it rains
Can a PV system tripping a RCD in wet weather?
If not, I will have to assume that tripping the RCD in wet weather has a different source and the PV system has nothing to do with it. The solar panels produce DC voltage, that is then converted to AC and stabilised before being applied to your mains. As such the technician is correct that the panels are not directly connected to the mains.
Why is my RCD tripping when it rains?
We have had no history of our RCD tripping until solar panels were fitted last month. Since then our RCD frequently trips when it rains. The technician who fitted the PV system told me it couldn't be anything to do with that, as the solar cell wiring was entirely separate from the house wiring which the RCD was protecting.
Can a solar PV share a 30mA RCD?
This is isolate the tripping problem from the household circuits. It is not ideal the solar pv sharing an RCD as the solar pv will have residual current and this coupled with any residual current already existing on the household circuits could well be enough to cross the tripping threashold of the 30mA RCD.
What happens if a shared PV system is tripping?
The issue with the PV being fed from the shared isn't just nuisance tripping. It will also affect disconnection times. If there is a fault of one of the circuits which are protected by the RCD, say for example the sockets, then the RCD will operate yet the PV system will still be feeding power to the circuit.
Why does my inverter keep tripping?
You can't supply the inverter through the RCD. It will cause the RCD to trip Start with switching the DC breaker off at the inverter so the panels aren't supplying the inverter with any power and then wet the panels again and see if the RCD trips. If the RCD does trip then this is definitely an AC problem.
Why does my solar meter trip?
You have an “upfront” RCD straight after the meter so any fault on your domestic or solar electrics could cause it to trip. Or there could always have been a residual leakage just under the trip sensitivity of the up front RCD hence the added leakage from the inverter now producing the trips.
