Hello, I’ll make my long story of my first world problem as short as possible…and Thanks in advance for any advice or guidance members of the community will share.
I have a little fishing boat and a 24v trolling motor. My research is telling me to make the investment in lithium batteries.
My issue is that I have no electric at the dock and need to create a solar solution to charge the batteries. The batteries I’m planning on purchasing are 12v 80 or 100amp…haven’t decided on what size yet. The batteries will be wired in “Series” per the manufacturer. The trolling motor has an 80 lb thrust and max amp draw of 56.
The boat will only be used on the weekends and the dock has full access to sun, so solar charging will not be an issue. My questions are as follows:
Can I use a single solar panel to charge both batteries at the same time? The batteries are wired in Series…will it harm the batteries to charge them in this fashion?
What size solar panel will I need? 50w? 100 w? 200w?…I have no idea
I plan on hooking up the solar charger to the batteries on Sunday evenings and leaving it to charge all week…will this be a problem?
I’ll have at least 4-5 days between uses so I’d like to know what is the minimum watt charger I’d need to provide adequate charging.
I’ve read I’ll need an MPPT converter…is that accurate?
I’m hoping there’s somebody out there who’s had this same issue and would like your guidance on what I’ll need to get a system that’ll provide a relatively hassle-free charge.
Thanks in advance for your help and guidance!
