Much the same as gav it looks great but a bit to technical for me, have also seen it done with those ceiling fans as well, i,m also quite conscious of fire risk on a boat, with gas diesel and battery’s there is a potential for a little spark to make a Big Bang, I have 480 amp hours of battery and a 2000watt inverter onboard and will be fitting solar panels this spring and probably a bigger better inverter a bit later on, if I was in an off grid cabin or something similar I would definitely give it a go, thanks king ?
