I have an MPPT 100/50 and it cycles on and off every few minutes. Sometimes it will charge for a few hours, other times it will run for 30 seconds, then shut off for 30-60 seconds. You can hear it clicking on, and almost a spring actuated noise when it cuts out.
I have 540AH of lithium and it is feeding a fridge and basic outlets. The appliances do NOT cycle on and off. The solar charger will cycle, feeding the batteries, then shut off. This happens at different battery levels, there does not seem to be a correlation there.
I have 800W of panels. It seems to shut off whenever it gets about 525W from the solar. It does have the bluetooth control option.
Is there a setting that limits max solar input power? Is something tripping the controller off?
I have searched the troubleshooting guide and this forum and have not seen a similar problem.
Thank you!!
