I can read voltage (the voltage I would expect to read) on the leads going from my solar isolator to my Smart Solar 250/100, but when I connect to the Smart Solar, it doesn't read or display any voltage. I also read no voltage on the terminals.
I checked polarity, I checked the MC4 connections, and I checked all of my connections on my Rich Solar panels (5S2P).
I sent the charge controller back to Bay Marine and they did a comprehensive test but found no problem with the unit and is sending it back to me.
The Bay Marine tech said that issue seems to be when the charge controller puts a load on the solar array and he gave me some ideas of things to check/test. However, 'm wondering if anyone in the Victron Community can give me some suggestions of things to check or perhaps has run into this exact issue and can give me even more direct info/ideas.
