Charger 2 w AC200max and battery bank

[ben446]

I am looking to expand my use of the Charger 2 by adding a 12v LiFePO4 to my current setup that is using a ac200max. The 12v LiFePO4 mainly is to power a 12v rooftop aircon.

A few ?s:

1. Can the Charger 2 charge the ac200max while also using shore power and its AC charger?
2. Can the Charger 2 charge the 12v LiFePO4 while also using shore power and its AC charger?
3. If not, do I need a disconnect for the 12v LiFePO4 while charging from the Charger 2?
4. Am I correct that the CHG port to 12v LiFePO4 will be slow charging with a max of 288w?
5. Can the ac200max be assigned to ‘reverse charge’ ie charge the 12v LiFePO4?
6. Keeping in mind conversion loss, while not on shore power, can I get faster charging by plugging the 12v LiFePO4 AC charger into the ac200max while using alternator charging?

My use cases are:

1. Use solar while parked to top off both the ac200max and the 12v LiFePO4
2. Alternator charging and some solar to charge / top off both the ac200max and the 12v LiFePO4
3. Use shore power to charge the 12v LiFePO4 for running the aircon while boondocking
4. In a pinch, use alternator idling charging to top both the ac200max and the 12v LiFePO4.

You need to read the charger 2 FAQ and PDF manual which has diagrams and answers so these questions. The charger 2 has lots of quirks, including if reverse charging the car batteries, it’s not charging anything else.
