So, your pair of batteries wired in series gives you 360 amp-hrs @ 12 VDC. That is the 20 hour rate which is the commonly used rating.
But, on high draw such as powering a microwave with the inverter, it will have substantially lower ratings.
If you have a 1500 watt microwave, it will take about 1600 watts from the battery (wiring and inverters are not 100% efficient).
1600 watts divided by 12 VDC= 133 amps! That is a very substantial draw from a 360 amp-hr battery bank.
