Hi there. A few months ago I had the cu replaced in the garage as the old one was well past it. Since the replacement one of the RCDs in the cu has been tripping on a regular basis.
I have narrowed it down to the solar panel system. The odd thing is that it only trips in damp or rainy weather and normally between 9- 10:30am- this may coincide with cooker/kettle/toaster being used also though. I did contact the system manufacturers and explained the problem. They said that it should run through a min 100mA rcd and that is why it is tripping. It runs through a 30ma rcd at present.
Where should I go from here? Is there a way to check for earth leakage from the panels? My research tells me to have a separate rcbo (?) for the solar system- is that correct?
I have noticed that the inverter clicks and the other day I was watching the rcd after resetting it and when it clicked the rcd tripped immediately.
Could someone please explain..
