6 FAQs about [Photovoltaic inverter trips after rain]
Can a solar inverter cause a trip?
Depending on the design of the electronics within the inverter it is possible that a leakage to earth from the panel could result in a trip. One way of determining this would be to switch off the isolator for the PV and see if you get any more trips, if that cures the issue the solar system in some way looks like the culprit.
Can a PV inverter trip an RCD?
The technician is incorrect. It is almost certain your PV inverter is transformerless, meaning there is no isolation between the grid and the PV panels. The result is PV leakage currents can indeed trip an RCD though inverters are supposed to check for and fault if such leakage exists though this feature can be disabled.
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.
How often does a solar inverter trip?
It is the main breaker of this solar distro panel that trips but only once per week or less. My inverter is the MPP PIP6048MT and is off grid in the respect of that the AC-in for it is supposed to be only in and not bi-directional.
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.
What tripping current is required for a solar system?
domestic installations, the RCD/RCBO must feature 30mA tripping current. This current is overly sensitive for solar systems. In addition, the 30mA threshold is the 16mA. form a capacitor between the solar array and the earth. This capacitor will result in leakage current which is quite common in solar systems. For some weather conditions,
