Read through many prior questions/answers without finding an answer.
Using the charger (HQ2109CLMQE) with a Smart Dongle since 9/2022 without issue. Have measured with a Volt meter, 20V from my 2 Renogy 100 watt panels and Battle Born battery voltage above 13V at the charger connections. BULK light is on solid, but no charging. Tried removing Solar V then Battery V from the charger, then reversed order reconnected to reset the charger. Same result. Tried resetting charger to factory settings and same results. Any ideas? Thanks
