So I have revised my ideas to set up with 2 (maybe 4) trojan 105's and a solar panel to keep them charged.
What size panel should I use? has anyone tired this?
I have a Fuzion 360

I started researching MPPT Solar Chargers before I bought my latest RV. MPPT Chargers increase charge current up to 30%. The benefits of MPPT solar charge controllers are greatest during cold weather, on cloudy or hazy days or when the battery is deeply discharged. They force the PV (photovolatic cells) in the solar panel to operate at voltage close to maximum power point to draw maximum available power...
The biggest drawback is cost.. They aren't cheap. I have a 25 Amp Blue Sky 2000E which cost me $250 bucks. I have seen cheap 25 amp non-mppt chargers go for less than half. It does make a difference. I get solar charge on my unit when a friend with similar setup without an MPPT Charger gets nothing in cloudy weather.
I have two 123Watt Sharp Solar Panels. They are rated at 7.4Amps Each.
I have 4 12Volt heavy duty batteries which equates to 400 amp hours. That's basically the weekly output of my two solar panels.
Here's a solar calculator that might help those who are trying to determine their needs. Good luck with your project!
