They look about 3ft tall on that photo

Actually, with the exclusion of Dunfixin’s post they’ve all been correct. Some have been simpler to understand than others but none of the rest have been wrong (unless I missed something).

But as three of us have been telling you, the size of the bank is irrelevant to the size of his generation. Maybe the previous owner was on shore power, maybe he got fed up with his batteries going flat, who knows?

Batavia is correct insofar as a water analogy works. Volts = pressure (or head, if you prefer) Amps = flow rate, which is dictated both by the pressure and by... Resistance = restriction to the flow. That is directly analogous to a simple circuit.

Agreed. A ‘trendy’ font for no purpose other than to appear trendy.

Actually, you said it ‘should be’ but I don’t really want to waste time splitting hairs over an irrelevance.

And therein is the reason why a 10 year old self fit-out may well not be RCD compliant. It doesn’t need to be.

Yeah, me too

OP hasn’t managed. He didn’t own the boat when he started this thread, hence his question.

No. As Theo points out, the batteries are only a storage medium. Their size is not (directly) relevant to the amount of generating capacity you require. You need to replace your usage plus up to 20% extra, ideally on a daily basis. Your battery bank needs to be at the very least twice the size of your daily usage but it could also be 5 times the size or even more, so has no relevance to the capacity of the solar charging source.

At what voltage?

So what were you proposing to go through the slots? Surely that would stick through just as much as the ends of hooks?

HOW much?! Oh... deer... with two ees
