Hi
I’m rather new to this and have been researching the Victron solar panels and notice that they do 2 versions of the 115W Mono. Series 4a & 4b.
The spec values appear to be the same, and the only difference I can see is that the 4b is 15mm longer, but surely that can’t be the only difference, as logic tells me that 4b is a newer model.
can anyone shed any light on this for me please.
Many thanks
