Quattro Grid/Battery Priority Settings

Hello All,

Probably a dumb question, but I have a Quattro II 2x120V installed in my motorhome. I initially set it up as a basic system with 4-100AH batteries, generator and shore connections. For that, it works flawlessly. My question is, can the Quattro be set to use battery power (inverting) to a certain charge state, before it would automatically kick back over to charge/passthrough? I added a solar MPPT 100/50 and a couple panels to the system, but when plugged in at my house, the solar of course doesn't help much as the Quattro keeps the batteries topped up.

I know it's dumb, but I like to keep my mini split on (or furnace) to keep a bare minimum climate control in there (80 in summer, 35-45 in winter) just to control some of the major temperature swings we see here (-30f to 95+). I typically have the RV outside, and the solar would keep up with it most of the times. But, with a small setup, one cloudy day can send it down quick. I would like to be able to have the system pull from the batteries until a certain percentage (50%? whatever might be recommended) and then switch back to charging without having to monitor constantly.

Overall, it's not a big deal. It amounts to 2-4 KWh per day, only about $14 per month. It's probably more for proof of concept, as well as feeling like an absolute waste of resources to heat and cool a spare home. The rest of the setup is pretty automatic, when traveling I run on full inverter mode. I have the Orion 12/12-50 which keeps on top of all consumption (Air, AC fridge, etc). I added the solar to assist the alternator charger, and maybe reduce the load on the alternator. I bought the kit to auto start the generator if the battery level gets too low, but I have not installed that yet. I meant for that to be used when overnight sleeping on our trips (have had a couple nights that the batteries died overnight.)

Thanks!
