Just traded in our Alpie with that exact setup. We had 6 batteries and the solar. Worked great actually as a trickle charger... kept the batteries charged when in storage. We did equalize once a year. Not a big deal really, just a setting on the inverter panel. We got 6.5 years out of our battery bank. We replaced them when we noticed they just didn't stay charged as long. Replacing all 6 is pricy.
We also had our inverter stop working when the temps were in the teens and wouldn't allow AC power into the rig. Fun times. The solution was a rebuilt one. That's an expensive piece of equipment.
