Hi,
I have a 48V system
I have 1 bipolar DC Breaker (TOB1Z-63A) between my PV and my SCC.
I have another TOB1Z-63A breaker between my SCC and my batteries.
For some reason, the breaker between my charge controller and the battery tripped this afternoon.
Lately we get some clouds so indeed, when the sun go thru, it get over the A I normally get when I have a clear sky
Normally I get about 32A going between the SCC and batteries, but with cloud it go higher of course, today after turning the breaker back on, I had at about 36A.
It is still way far than the 63A rating of that breaker (My SCC is rated for 60A and recommended 63A breaker and I don't expect to really go over 40A)
There is no short or anything like that, everything work just fine, except that the breaker was tripped.
Is there is something I don't know about bipolar breaker? Should I get the 125A flavor or switch to normal one pole model?
I also noticed that the breakers are "warm" while the wire are "coldish"
