Re: Illustrated Guide to Solar Installations on Boats
Pardon my ignorance... could you explain me the fuse rating? why a 40A fuse for the MPPT that is rated 30A? Is the latter well protected with such fuse?
Thanks

Oops. My bad. It’s a 30A breaker between the PV and MPPT.. Max fuse per panel is 15A and there are 2 wired in parallel. There is also a 30A inline fuse off the panel wire combine before it comes into the cabin. Belts and suspenders, I suppose. Thanks for noticing.

The fuse protects the wire. It should be sized higher than max load and lower than the wire's ampacity.
