looks like you have the answers here. When we have this issue the way we
have fixed in the past is re route the battery positive from the CC to the
battery terminal it self. This makes the inverter take the current form
the batteries not from the CC capacitors. See Jay's note on battery
health
What can sometimes happen when the charge controller is wired
electrically close to
the inverter and long-ish battery cables are used from that connection
point to the batteries is
that surge currents from the inverter DC connection will be drawn from
the charge
controller and its batter

Is this breaker perchance a GFDI breaker? If so, the tripping could be
indication of current flow in the bonding leg. This is a more nuanced
problem.

HI Mac,
This is a pretty common event.
Yes the CC is dumping its caps into the load as the load is in a sense
overloading the batteries. IE they are not able to deliver the amps and so the
CC is helping.
A larger breaker might help, or one technique I’ve used before ( advice from
midnight) is
Maybe I making an assumption here that I shouldn’t but I hope you don’t mean
that you had moved the breaker to the battery box on the inside?
If you ever been in a dark room when one of those did it’s job it’s really
impressive and you sure don’t want it in the battery box if it ever has to trip
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.

Hi Mac, I have seen a single Magnum on starting a 1.5 HP motor draw over
300 amps 48 volts surge. In three years it has never failed to start that
motor. I assume the charge controller is trying to use its capacitors to
supply the current to the inverter, and the starting surge is tripping the

Hi Mac,
What size breaker is tripping? I assume you are running at 48 v?

Yes, it's an air compressor, but it's tripping the charge controller
breaker, not an AC breaker.

Hi Mac,
Just off the top of my head I’d say you’ve likely got an air compressor with a
high locked rotor rating, at least with the info you’ve provided.

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
