I have 2 400watt arrays with separate 100/30 Smart Solar controllers on my RV. Every so often, they both stop producing power. This seems to happen once a month, or so. This will occur when the 400AH LiFePo4 are in need of a charge, full sun, each array 45 volts. After disabling and enabling charging from the phone APP all is good. I've had this happen while away for 20 days, and had no charging for 10 days. I had to reset as I described above. Any ideas on why this randomly happens?
Thanks,
Bruce
