My solar system is five, four panel, 1000w parallel strings to a 6 in 2 out combiner box then to 5000W inverters also operating in parallel. Typically, I feed all the solar to the master inverter and only turn the second slave inverter on when I need high AC draws. The battery is Lifepo4 840ah @48v.
The combiner box is rated at 63amps per inverter. However, if solar production is a constant >25 amps, then the one 63amp breaker in use gets very hot.
The beaker is 4 pole with the negative passing through once and the postive passing through the remaining three poles one after the other.
Why does the positive pass through three poles in series? Does this contribute to the over heating? Any other suggestions in what to look at?
See photos below.
Many thanks.
