[RE-wrenches] Outback Radian 8048 Main AC Breaker Trip with Generator

[Jon Siegenthaler]

Hey folks,
I went to investigate 3 Radian 8048A's that had the master inverter slowly
die from salty air. The newest slave that was added to the existing system
of 2 radians was programmed to be the master and the AGS was set to the new
master as well. The corroded ex-master was replaced with a new radian (now
a slave) and the system runs fine.

Except when the generator runs for about 20 minutes. After 20 minutes the
main AC breaker trips and the power goes out on the system. It's clear that
the AC output must be seeing more than or equal to 50A and that's causing
the trip but I cannot figure out why this only happens with the generator
running.

Also when the generator is running an error of overcurrent will occur and
show an imbalance of 34A to 108A from phase A to B. Eventually the current
will come closer together and the error will disappear. However during the
imbalance I will check the actual generator output conductors with my
amprobe and see around 43A to 48A phase A to B.

Has anyone experienced this or know what the best solution would be to
resolve this issue?
