It is easy to leak electricity when the air is humid in rain, indicating that the components, cables, or live parts of the inverter in the system have insulation damage. Generally, the inverter reports a low insulation resistance fault, or the leakage protection switch trips. Once the photovoltaic modules, cables, connectors, switches and other ...
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.
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,
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.
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.
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.
You can't categorically say that it is not the PV without testing. The inverter itself could have earth leakage or, if transformerless, could be leaking AC through the array via bonding (roof systems almost never are bonded though), or through the wet building to earth when it rains. Easily eliminated by switching off PV at AC isolator next time.

I have been working my way through an installation looking for why the RCD trips in light misty rain. I have eliminated all outside installations the only thing left outside the building are the solar panels. I know little to nothing about the PV installation. So my question is, is there anything on the roof that can cause the RCD to trip?
So I''ve finished the infinisolar super 4kw installation and the split db. The low amps side has its own earth leakage and neutral bar. It starts up on batteries and runs with no trips. But when I switch the main supply back it trips …
Hybrid solar systems are known to generate power similarly to the conventional grid-tie solar system, but it use unique hybrid inverters and batteries to store energy for later usage. Their ability to save energy has enabled it to act as a backup power supply similar to the UPS system. Hybrid systems combine solar power from a photovoltaic system with a power-generating …
Tripping once a week is more than the typical "once-a-year-nuisance-trip-due-to-those-pesky-inductive-loads-all-switching-on-at-the-same-time". Just adding ground rod by the inverter and keeping its grounding as TN-C-S sounds OK, as that is just PME, but I''d question whether it would be good practice to disconnect the grid earth from the ...
When an earth leakage trips, it means the return current finds a way past the earth leakage, and this almost always means you have return current running past the earth leakage on an earth wire (which should never …

The enhancements led to significant improvements in the solar power system''s reliability and efficiency, even during adverse weather conditions. Consistent Energy Supply: The integration of batteries ensured that the homeowner had a reliable power source even on the cloudiest days. The stored energy bridged the gap when solar production was low.

The panels / system works perfectly until they get wet (rain or hose pipe when testing). Within 30 seconds of any one of the groups of 4 panels getting wet, it trips the 30ma RCD on the Grid side of the inverter.
Having the solar circuit on it''s own RCBO may be enough to fix the problem for you, or it might not. The instructions for my Power One Aurora inverter say that it should have a 300mA RCD. Presumably the manufacturers are aware of this problem. A 100mA one would most likely be an improvement, especially if it''s a time-delayed one.

Solar panels are able to run in the rain, in most cases, because they are designed to capture and convert light into electricity. They will continue to generate power even during rainy or cloudy weather but it could be at a reduced efficiency. It''s important to note, however, that in areas with particularly extreme weather, their performance could be considerably impacted.
leakage current which is quite common in solar systems. For some weather conditions, such as rainy and cloudy days, this common-mode capacitor will be increased and will cause a higher leakage current. This could trigger the RCD/RCBO. 2.
