it's time to build my first solar
setup. i've been researching for quite a while now and trying to learn about what i need to get done. i'm not looking for some showcase solar
set up. and we aren't huge electricity drainers. this is going to be a budget project that simply gets the job done.
i have a 28ft. sailboat and i'm looking to power a chartplotter
, auto tiller, laptop
, and lighting
(running, navs, mast
, and interior). we use candles, lanterns, and AAA powered LEDS half the time anyways. my outboard motor
has an alternator
which helps big time on keeping them charging
, but i won't always be using that and don't want to depend on gasoline all the time.
so i bought some AGM
batteries a while back and installed them on my boat. when i purchased the batteries the guy also gave me new wiring
and the used charge controller that he had successfully working with his setup. (so i bought most everything minus the panel.)
i guess my main question is to please take a look at what i have to work with. let me know your opinion as to if this puzzle can be put together with the pieces i have to offer.
here is the charge controller i have.
i know i've read a lot about everyones MPPT
and it sounds like maybe that's what i need. but if i can get this one to do a similar job and not spend the money
i'm ok with that. he gave me about 15ft. of heavy gauge wire. it's not infront of me right now so i'm not exactly sure what thickness but he said its the same spool he's been using and it's expensive.
the batteries i have are NorthStar (NSB-M12-210FT)
here is a link to my blog
that will show you and tell you more about them. another question is, will this charge controller be compatible with these batteries?
here is a solar panel that i am interested in.
i've been searching around for something between 100-180W just because of the actual size of the panel and because i think that will be more than enough to keep those big batteries topped off, especially if we're using minimal power and occasionally running the motor
. more questions, do these batteries hold more power than your average 12v? if so, is it by a lot? also, will this panel be strong enough to keep them topped off with moderate power consumption
? and, will this panel be compatible in a setup with that controller and those batteries?
i saw that i need to purchase
MC4 clips to put on my cables
. if i've got it right it should work out and go like this: solar panel - MC4 cable connect - cable wire- C40 charge controller - cable wire - batteries. correct?
also i saw they sell an optional LCD digital display. probably not necessary but a wise add-on worth purchasing
thank you for your time and especially any help.
