Trik L Start with 100 watts of solar

[ledcomp]

Well I got lazy and let the RV sit for a few months, bad idea. First problem was a dead coach battery. I was thinking it might be dead but I can start the onan and put a charger on it. Second problem, the onan cranks but will not start. I bought this RV a few years ago and I put a new carb on it because it sat to long. Hope i didnt mess up this one.

Anyway, the real question, with 100 watts of solar can I maintain 2 group 27 house batteries and 1 coach battery using a Trik L Start. Winter will make about 15 amps a day summer is 30 amps a day. The controller is a Morning Star MPPT. The house load is 6AH/Day im not sure on the coach, Dodge B3500 but it has sat over a month before and started right up so it cant be very much.

The MPPT controller charges the house bank. The Trik l start allows the coach battery to charge from the house bank.

The solar charge controller will usually (I'm not an expert on this, YMMV) charge only the house batteries.

The Trik-l-start steals a small percentage of the charge off the house batteries to charge the coach battery. I had one installed on my class "C" for over 8 years, and never had to jump the battery to start the engine. It wasn't on solar, but was on a timer that only charged the house batteries for one hour a day. Probably about the same amperage as your solar would provide.

The Trik-L-start is a wonderful solution to a coach battery charging problem.

I would keep an eye on it if not using a disconnect.
Otherwise 100w is plenty for the 3 batteries.
