I leave mine connected year round, but I do have wet six volt batteries on my coach for the house part. So that means that I have to check the battery water level at least every thirty days, just to be on the safe side. The inverter/charger has to be on if you want your batteries charged. Does not mean the inverter part has to be on at all, just the charger. It will keep your batteries charged all the time. With AGM you do not even have to worry about water levels, so you should be OK hooked up to the 110 shore power. It will keep your house batteries charged, but not the chassis batteries.
