August 5, 2017 at 3:27 PM Official Post #2 Ok, 1.4.7 is very very very very old. We don't support that anymore. However the error message is something you can just ignore, so that'd be a solution if everything else works..
August 5, 2017 at 8:55 PM Official Post #3 It's caused by a bug somewhere in either IC2 or CompactSolars.
