Hi Jean and Erwin
I had trouble with the Electrobloc, which Allan at A&N sorted about 5 years ago.On his recommendation I have 2 Varta LDF’s. one habitation and the other is the starter. I was told a bank of batteries will only perform as well as the worse one; so ideally they should be same age and capacity. They have 5 yr warranty and have performed satisfactorily.
I have an 80w solar feeding through a schaudt controller which is fine for us through the summer, but we don’t use much power except in winter, when we use hookup more.
Hope you get it sorted
