Hi all I’m new here, my smart blue solar controller has malfunctioned. Losses connection regularly and is not charging the batteries, tried resetting using the puk code but keep returning error. So I’m stuck any help would be great. Thanks
What do you mean looses connection regularly? Do you mean over bluetooth? (Hence the puk reset)
Sometimes a power cycle helps.
Disconnect solar
Disconnect battery
Wait a few minutes
Reconnect battery (check polarity if you dont have a disconnect)
Reconnect solar
Test again
