That excellent real life data shows why hitting your batteries in the morning with all the Amps you can followed by letting solar top up all day is the way to go.

Solar has made a world of difference to our electrical systems. I struggled constantly with an undersized battery bank and alternator and vowed never to do that again. Now with a properly sized solar array one really doesn't need a huge alternator to keep the battery bank charged and healthy.

how big is your genny? how big is your alt?

most 2000 watt inverter /chargers I've seen are 100a (IE magnum 2012)

I would definatly leave the existing 20a in connected to the engine battery, and you may as well connect it to the house as well. that'll give you an extra 20 to the house. and a backup if the charger / inverter fails. or consider replacing it with a 40-60a charger. so you'll have ~100 total. asumming you are sticking with the current inverter / charger and don't want to send it back.

even if you get a biger inverter / charge I would leave the small charger in.
