I looked through several threads but cant find exactly what I am looking for, so I am asking for advice. Our 31' is being moved to a dock
w/out power. We do have a portable generator
we use when needed but would feel better having a solar
panel to keep batteries
charged. Currently the batteries
consist of 1 grp 29 deep cycle 115 ah and one grp 27 90 ah battery
. We dont run a fridge or anything while docked unless the generator
is on. We take many 2-4 day long trips a year, and also plan a 2 week trip but will have the generator for when needed. I would prefer enough solar
juice to ensure the batteries stay charged for when we want to take her out, and also to ensure the bilge
pumps will function. What size would be needed and what's best, also a charge controller. At our camp we have a small 10 amp panel on a deep cycle battery
and I am much less then impressed with its performance.
Also wondering how much juice would be needed to run the auto helm
, (st3000) and gps
for an entire day while not draining the batteries down so much the engine
would not start.
Thanks for any input, and reccomendations,
