Hi. I read and then asked a noob question and then read more and am about ready to go forward. Have a question and am looking for comments on this setup for a system:
Application:
1) Kayak, a fat one
2) FishFinder: 650mA draw, input 10-20vDC
3) Use: 6-14 hours a day, summer. 30 times a year MAX. I WILL fish in overcast or downpours.
4) have charging station at night for top up.
5) Use: sometimes no charging station at night, but I can go easy with the electronics.
System:
1) 2x 10Ah AGM batteries in parallel
2) panel: 20W-30W panel. output 12V-18V to be determined, probably poly
3) controller: el cheapo, PWM, adjustable: https://www.amazon.com/Controller-Re...ar+mohoo&psc=1
My own question is about charging the AGM. 12V isn't going to cut it right? I am going to have to get a 15-18V panel and eat the loss on the PWM. Correct?
comments?
thanks.
