Battery questions
I know there are some very knowledgeable folks on this topic, hoping you'll chime in. Current set up is a small 17' hybrid that HAD a new (Costco), single group 27 12v (105 AH) battery. I use a 20...

No your math is wrong
Your two sixs can be 416 @ 6v
Or 208 @ 12v
It can Not be 416 @ 12v
When batteries of the same voltage are paralleled you add the Amphrs and voltage stays the same
When batteries are put in series you add the volts, and the amp hrs stay the same
75 amps is high current for a 6v battery, remember they are in series to get 12v , like flashlight cells
Two 12v in parallel would only need to deliver 37.5 amps each
If you were not making inverter powered coffee with high amp load , i would recommend the two 6v, which are great for lighting etc..
As it stands, i recommend the two 12v agm in parallel
These can produce the needed amps to power the inverter without being severely damaged like your previous single 12v
Do run the generator for the full 4 hours each day,
When you can, adding some solar would be very good for the batteries

So is my math correct?
Two 208 AH 6V batteries (416 AH at 6V) would = 208 AH(?)
The 6V batteries are $150 each, the 12V batteries are $110 each.
So I guess my question is....
Why would I be better off paying $300 for 208 AH (Two 6 V batteries) versus $220 for 210 AH (Two 12V batteries)?
