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...

What we have found here is unless both battery groups are fully charged we won't see max performance. Also when one group is down in % of charge it will draw the good side fully charged battery group down to the weaker batteries % of charge.
The 1000WATT INVERTER will draw around 80AMPS plus loses from your battery bank. That is alot of current and you can look at the battery specs which usually list capacity for 20AMPS and 75AMPs and will tell you how many minutes the battery will produce 12VDC at these loads. You can judge from those readings what to expect.
A typical Trojan 27TMX battery specs show it will produce 12VDC @25AMPS for 175 minutes (2.9 hours) and 12VDC @75AMPS for 45 minutes before running down to 0% charge (10.5VDC)... You of course have to only use half those numbers as you never really want to run down your batteries below 50% (12.0VDC) so that you will not do any harm to the batteries. Not alot of time even for a couple of batteries.
