So solar panel stuck on roof and covered up so no power being generated
Hole drilled in roof and wires from solar panel fed through taking great pains to retain live marker on appropriate wire. All fittings and wire sikaflexed down.
Fitted controller in what I call the electric cupboard.
Pulled wires through top of cupboards and opps the live wire marker has disappeared
I know to wire the battery to the controller first but if I wire the solar panel incorrectly will the controller intervene and not let the system work.
I was having the solar panel fitted by someone but 'life' got in the way.
