Are you sure? Method 3 requires equal amps and voltage from all 3 batteries. How are you doing this with one battery located 8' away?
A 900W MW draws 65A+ and not the best for starting batteries which a Marine battery is - ie a compromised starting battery. Might be OK and might cause a low voltage fault.
Hi CA Traveler,
He could do method #3 if the leads to the battery bank go to a buss bar that is 5 feet from any battery. i.e. all wires the same length.
I'd suggest that a 900 watt microwave may draw about 100 amps. I know my 1570 watt Dometic draws 185 amps.
I was able to successfully operate the Dometic microwave on 3 Marine jars for more than a few minutes. I have two banks--and one was 3, the other was 4 batteries. Switching allowed me to do either/or/both/off.
