I'm looking for some advice on setting up solar on our new to us boat - there's no solar in place so we're starting from scratch and will be having an arch built to accommodate the panels.
The best fit is 3 x 175w Monocrystalline Blue Solar panels - I've been advised to wire each of these with their own MPPT controller so if one panel is shaded but another not, it won't affect the output of the other panels. This is important as we'll have radar mounted above and will cast a shadow at some point in addition to the mast and boom. Are the 75/15 Mppt controllers the best fit for this?
At the moment, we have 2 x 180ah lead acid batteries and a 95ah engine starter battery.
I'm looking to upgrade these to 4 x 100ah lithium life po4 batteries + the engine starter battery but this may be a while after the solar is fitted.
We are running on a 12v system and have a 24v system when on shore power. We'd like to be able to use the 24v system when away from land as we'll be mostly self sufficient and will need to charge laptops etc. - which inverter will we need? And how would all of this be wired for the best efficiency? I would like all the panels to charge all the batteries, rather than one panel designated to one battery.
