Hi,
I have a transfer switch from Victron. It is used to switch between solar power & grid power.
When a switchover happens, e.g. from solar to grid, while there is a heavy load (>2000W) sometimes the grid RCD trips.
I think the RCD trips when an arc occurs inside the B&J R40-22 relay of the transfer switch.
What can I buy from Victron to fix the problem?
FYI, not clear to me why Victron is using a relay instead of a dual contactor with mechanical interlock to do the switchover?
The switchover would be a bit longer than 20msec but for sure no arc can occur between the 2 power sources that may trip an RCD (type A , B, ..)
Thanks in advance for your response.
Regards,
Filip
