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.

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?
