I suspect your 220AH Dual 6VDC battery setup for 12VDC is not going to like a good 100AMP PLUS DC CURRENT demand even for a short period of time.
I use a 600WATT PSW INVERTER for my home entertainment and other emergency ops items and can live with a 20AMPS power drain off my battery setup for hours...
Most of the time we use around 20AMPS of DC CURRENT DEMAND from 6PM to 11PM and then things drop back to the parasitic 1-2AMPs DC current demand after that.
When we want to brew up some coffee I always pull out the generator and it only takes around 5 minutes of generator run time to grind and brew our fresh made bean coffee brew. This pours up into a thermos server and stays hot for many hours...
In my case we are usually running the generator each day at 8AM in the mornings when allowed to run one to let the on-board converter/charger re-charge our 255AH battery bank to a 90% charge state in a quick three hour generator run time. This is usually the time we make our coffee for the day.
Adding solar would just help me not have to run the generator as much each morning. I would need a pretty large SOLAR array to overcome the initial HIGH DC CURRENT demand when the batteries first see the 14.4VDC bulk charge. After an hour of running the generator I could then revert to SOLAR PANEL to finish my battery charge to at least a 90% charge state before losing HIGH SUN.
In my case I have to start each day living off the batteries with at least a 90% charge state otherwise my batteries won't make it until 8AM the next morning when I am allowed to run my generator here on the East side of the US. Everyone seems to have generator run time restrictions in place here just about everywhere we camp at. Not many DISPERSED places here on the East side of the US like there is out West. When my 255AH Battery bank drops to around 12.0VDC then I have to stop using them until they get re-charged again.
We get by just fine using our 600WATT PSW AIMS Inverter for LED lights and Home Entertainment and emergency items.
