unfortunately i disabled the bluetooth a while ago and now waiting for the USB cable.
i am on a camping place somewhere in south portugal.
i have a new set of 2 batteries in parallel and the victron bluesolar 100 20
it was working absolutely fantastic and one day i realize the blue light is blinking and the battery is only being very very very minimally charged.
i have 300 W on the roof and on good days was receiving 260W (before i disabled the bluetooth)
a multimeter gives me 1.7 to 2V when the PV is connected and 20V when the PV is disconnect from the charger. the Battery is giving me 12.47 now 12.35 as its slowly dropping. ampere i cannot read as i blew the amper fuse in my multimeter on a different thing.
To me it seems that something is wrong the the PV but i went on the roof and everything seems like it was before. could it be that the PV blew a fuse because of heat or something?
if i remember correctly the blue light used to be almost always on not blinking every few seconds. the other lights are off
