Hello all.

We have a 2018 3120rl. We ordered it with the Onan 5500 LP generator, and it work well. We've only used it a few times, as we mostly camp with hookups, however we have found a dry camping spot we really like and want to visit it more often The generator is great, quiet, efficient, and handles everything we throw at it. Our issue when we dry camp is the battery power during quiet times. We're not looking to run the a/c, or anything big, (the tv and satellite receiver would be nice), but the single battery our unit came with is dead in the morning, just running a couple of lights. We did not even attempt to use the heater, as it was not needed. With the porch and front cap light, and the fan blowing in the refrigerator on LP mode, the battery was so dead I had to hook it up to the truck just to start te generator.

I am planning to replace the battery with at least 2 Trojan T105's, and maybe even 4 T105's. Since we store it in a facility without power, I was thinking to get at least one solar panel to keep the batteries charged...... I did read in another post that someone suggested changing the internal charger / power supply to a smart charger is a must, and if recommended I intend to make that change too.

Therefore, my question is; is one 100 watt panel enough to charge / trickle charge my new batteries...?

Thanks
