So I put in my 3 new EG4 Powerpro batteries to replace my single Fortress 18kw. I had the Fortress connected with a 4/0 flexible cable to my two Sol-ark 12k's.
The new Eg4's only accept 2/0 wire from the inverter to the main battery. I noticed today that the 2/0 flex cable gets warm when pushing a lot of power like charging my car. Now they don't get hot, but they do get warm. If I had to choose a temp I would say about 80-90 degrees. Now the more solid 12 strand 2/0 cable do not get warm at all, just the flex.
I know wires do heat up with current, I just don't know what is acceptable. Should I be concerned? Is this a problem that would only get worse over time?
