To explain, I've had a 150w panel on roof for a couple of years and always seemed OK. I also bought one of them folding/tilting 100w jobbies. This never seemed to add much and soon packed up. So I've in contact with the seller in the UK to sort it. I'm currently in Lanzarote.
Firstly the old set up. I have 2 x 110 AH batteries and they show 12.6v linked up.
Overnight I left the fridge and lights on, (on purpose) and this totally flattened the batteries. This morning I turned everything off and within a few hours the batteries had plenty of life in them so the old solar system is OK
The seller asked me to check the input and output values on both systems.
This system showed 20.7 on the input and also 20.7 on the output side ???. I was told it should be near 12v, but as it seems to be putting juice into the batteries, should I be worried ?
This is in the late afternoon sun at a low angle
