Re: Fac Bfr error on Sunny boy 2500
Bob, welcome to the forum.
Needing a 30 amp fuse + Breakers too? And blowing on of the 30 amp fuses on a 12.5 amp output?
In certain applications, fuses are used instead of circuit breakers (there are special high amp interrupt current)--But that is not the case here.
And, there is (almost always) a solar array fuse requirement (when there are three or more parallel solar panel strings, each string should have a series protection fuse/breaker to protect a sorted solar panel from being fed by the parallel connected panels).
Anyway, I am not exactly sure if you are asking questions about solar array fuses--Or the 120/240 VAC output fuse/breaker (and blown 30 amp fuse--which is very confusing as a properly operating GT inverter should never output over its maximum output current rating).
20x BP 4175B panels (replacement) + Xantrex GT 3.3 inverter for 3kW Grid Tied system + Honda eu2000i Inverter/Generator for emergency backup.
