Hello all,
First post, been looking around for a few days, but couldn't find a close enough situation to get the advice I'm looking for.
We have a 21' trailer, and I estimate we use 30-35Ah per day based on the 100Ah reserve (2 group 27's @ 12v), and needing to run the generator after 3-4 days. I'm looking at a 200W kit from Renogy, but the problem is here in NY, there will always be partial shade due to trees around the site. Best case, I leave the unit on the ground and move it around during the day.
My thoughts are a MPPT with the panels in series would cut my current in half, but the higher voltage would keep the current flowing longer. 6A estimated X 7 hours = 42 Ah , vs. PWM where at least one panel might be in partial shade, and the time that I can keep the voltage above 14V is a big unknown..
I'm probably missing a lot here, so if anyone has a similar set-up and could give me some insights, it would be greatly appreciated!
Thanks
Looney
