pilotfish Posted January 10, 2018 Share Posted January 10, 2018 Without being able to see the scale it is tough to know what is going on, but my best guess is as follows; The graphs are ICC output using SOC as measured by Axpert (based on battery voltage) and not Victron BMV (based on amps in/out) Your batteries are at 100% with with very low other loads so PV output is low, You have a load which is cycling at regular intervals (like a pump or fridge compressor), When the load kicks in the MPPT is unable to respond fast enough so the batteries are initially supplying the power required, As the battery current increases your battery voltage drops, The drop in battery voltage is reported by Axpert as a drop in SOC (which is nonsense), The MPPT then starts to pick up the slack, by which time the pump/compressor has either stopped naturally or stalled because it is too high for the inverter. If the load is running as it should then there is nothing to worry about. Quote Link to comment Share on other sites More sharing options...
