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,
