Calling on Solar Techies
I have been thinking of going solar for some time and decided to pull the plug. My wants are a 400 to 500 watt system. I have four 12 volt batteries with 340ah. I am not planning on changing b...

Dogbone is 120v, nothing to do with your 12v.
Try this test--with the battery bank as is and no 12v things running, what is the voltage? Then turn on the inverter and run something as big as it will, and what is the voltage now?
This is to see if the bank has too much diff between resting and loaded voltages. A bad battery can show decent voltage but collapse under load.
Now rewire the bank using just the good batts, isolating the weak one. Do the same test and see what the diff is resting and loaded.
The Dogbone is part of the process of getting power to the microwave? I read that some come with 14ga wire which seems a little lite. That could be a factor when running high wattage appliances don't you think. I did find a dogbone that comes with 10ga wire.
I will try your voltage test. Do you recommend testing voltage at the batteries or at the Inverter?
As far as removing and rewiring the batts, I think I would just replace them all with 6 volts.
