Mac,
I had 2 midnite charge controllers trip breakers and eventually fail the
charge controllers on a Magnum system, moved the battery breaker from
the battery positive bus direct to the batteries and problem went away.

Hello wrenches,
I've got a mysterious breaker tripping that I need some ideas on how to
fix.
Original system:
Array 6 x 235W Kyocera modules
1 x Outback FM60 charge controller
1 x Magnum MS 4024 PAE inverter
Upgraded system we stacked a second inverter to accommodate an air
compressor:
Array 6 x 235W Kyocera modules
1 x Outback FM60 charge controller
*2 x Magnum MS 4024 PAE inverter*
There have been no changes to the solar array, just to the inverter
side of
the system. We have been getting intermittent breaker tripping (a
couple
of weeks between) on the battery breaker side of the charge controller.
The basics have been checked and rechecked. Torque is good on all
sides of
the breaker all the way to the battery bussing.
The only thing that I can think of is that during a surge on the AC
side
its sucking enough current out of the charge controller caps to trip
this
breaker occasionally.
Has anyone experienced this? The only way I can see to fix it is to go
with a larger breaker ampacity, but maybe there is something better.
Does
anyone no how quickly the max current setting in the Outback can
respond,
would dropping this help?
Thanks
