Hi,
We have a Multiplus 24/3000/70. Our "mains" supply comes from a community hydro-electric turbine (that supplies 9 households) which generally supplies between 500w and 2kw to each household. We also have a battery bank for Power Assist and also when the hydro trips/stops working.
The mains/hydro (240v, 50Hz) supply comes through a white box that contains a 30mA RCD and then through to the inverter and than out to a consumer unit and onwards to the house.
This system has been running very well since it was first installed in the summer of 2018. However, in recent weeks the RCD in the white box has been tripping several times a day. We have replaced the RCD with a new one but are still having problems with the tripping. Our electrician has said that he thinks our inverter, while operating quite normally, is leaking current to earth which is causing the sensitive RCD to trip. He would like to know what value of RCD is recommended by Victron (he suspects it will be 100mA)? Can anyone help?
Just one other thing, our hydro-electric turbine has just collapsed this week (new bearings needed...or some other mechanical issue). I was wondering if, in the weeks preceding the collapse of the turbine, it wasn't running well and causing fluctuations in frequency/voltage/current and it was these fluctuations causing the RCD to trip....although, having said this, none of the other households fed linked to the hydro seemed to be having issues.
Thank you.
Best wishes,
Leander
