6 FAQs about [The photovoltaic panel trips when flushing the distribution box]

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.

How to check if a solar panel is tripping?

Now you have to go and check the circuit breaker in the solar power system. Take a look at the service panel. The breakers should be all lined up in a row in the ‘ON’ position. If not your circuit breaker is tripping and causing the solar panel to trip. Also, remember to check if the inverter is working properly.

Why is my solar panel tripping?

Take a look at the service panel. The breakers should be all lined up in a row in the ‘ON’ position. If not your circuit breaker is tripping and causing the solar panel to trip. Also, remember to check if the inverter is working properly. Sometimes inverter glitch triggers this issue. More about inverters will be discussed in later sections.

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 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 is my PV system Tripping the main RCD?

It sounds like your system is wired wrong. A PV system should not be on a shared RCD, so if your PV system is tripping the main RCD it must be wired in the wrong side of it. There have been many long threads on this very point. A PV system should be on its own RCD if one is needed at all.
