Hi, I just received my smartsolar 75/15 and after updating the 2 firmwares, each time i connect it give me:
Err 119 - Settings data lost
According manual
The charger cannot read its configuration, and stopped.
This error will not auto-reset. To get it working again:
First, restore it to factory defaults.
Disconnect the charge controller from all power-sources
wait 3 minutes, and power up again.
Reconfigure the charger.
But it doesn't help, when i first connected, it asked me to update some firm to 2.22 i think and other firm to 1.39 if i remember well, is there anything else i could do? Should i return it already?
Thanks
