When you ran your refrigerator on the two GP 29 batteries, what was the battery charge level/end voltage after the 24 hours? I ask because if your batteries are typical "marine deep cycle batteries", most manufacturers recommend not discharging beyond 70% to prolong life. That equates to a battery voltage of around 12.3 volts. Many inverters will operate down to about 11.5 volts before they shut down from low input voltage. 11.8 VDC equates to a battery charge level of around 30%. Discharging "marine deep cycle batteries" to that low level repeatedly will shorten their usable life significantly.
