Drawing off two banks thru Switch?
I have split my 430Ah bank into two 215's, and I will soon be installing a Blue Sea switch with 1, 2, or 'both' settings. I realized last night, my cheapo 700w Walmart microwave, which is rated at 105...

Hi Roy,
With respect, a 1000 watt load on a 430 amp bank will draw far more than 80 amps.
It is moot because the OP's inverter is not large enough to run the microwave.
OP,
The load will be shared as smk said--determined by the resistance to the battery banks.
I use simple Napa switches to conjoin my battery banks and feed the inverter. That way I can shut off the dc power to the inverter.
So far, the inverter has done o.k with the microwave's 1280w draw, running for short stints of up to 3 or 4 minutes (on the 430 bank)... enough time to cook some scrambled eggs the way I like them. It has never set off any alarms, yet.
The other day I ran my pm4b off one of the 215's,thru the inverter, to test its input current. The Trimetric said about -90a. From the near full bank, the inverter warned me, but kept the pm running for the 20 seconds it took to test it; but off the less than full bank the inverter soon shut down.
