Wow, lots of good info here!
The excel solar
calculator is awesome! Thanks for that.
Voltage drop chart, Thank you.
As far as refridgeration, we have a dometic cf-50 (kinda looks like a gray cooler). Its AC/DC, it draws .7 amps AC and 7 amps DC (I just looked that info up, ouch!), however it doesnt run that often. If i had to guess I'd say it runs on average 10 minutes an hour, maybe 15 minutes an hour in the summer. So about 42 AH a day in summer. (maybe a Yeti cooler and a block of ice a week could be a viable alternative)
My reason for wanting dedicated panels
and batteries for engine
is primarily redundancy and simplicity. I guess I could run the windlass
off one battery
(just start the engine before I use the windlass so I get the benefit of the altenator). With that said there have been some good points made here about Automatic Charge Relays.
May have to rethink the whole dedicated panels
scenario... I'd rather change my mind a few times BEFORE I spend the money
1)I may have to get creative in how they are mounted due to space constraints. AGMs dont spill and can be mounted in any orientation
2)I live on the boat full time and I sleep in the berth that houses the batteries underneath it. The fact that they dont off gas anything will help me sleep better (pun intended). The thought of hydrogen off gassing inches from my sleeping head
creeps me out, even if its me just being paranoid.
I'm starting to buy stuff now and will be starting the install on days over 40 degrees thru Jan Feb and March. I'm sure I'll have
Has anyone used the Renogy brand panels on Amazon? The price
seems right and the reviews
are good, I'd just like to hear if anyone here has any real world feedback. Or has anybody recently bought a different brand of affordable solar panels
they would recommend?
Sorry if my response is a bit all over the place...
Thanks for the insight so far, you guys are the best.
