Am I asking to much from 2x T105's?
I posted a month or so ago about my new solar install, and some issues I was having with the low voltage alarm on my Xantrek 2000W Prowatt while running my coffee maker (Tassimo). I was able to check...

Marc,
Just did a little experiment for you. My setup is very similar to yours. I also have the Prowatt2000. I have four Energizer GC2s in series parallel through a selector switch so I can power from all four (normal) or select either pair when I wish to equalize while running off the other pair. The bank positives are connected to the selector switch by 1/0 cable and the negatives are connected to the shunt also by 1/0. Total cable length (+ & -) is about 6 ft.
I selected one pair so that configuration is actually a little worse than yours--longer, smaller cable.
The battery bank was fully charged. I plugged in a 1600 watt hairdryer that pulled 122 amps from the batteries according to the Trimetric. Solar was also contributing 22 amps. The voltage dropped to 11.7 according to the meter on the inverter and also the Trimetric. The inverter also showed 1600 watts output. I ran it for two minutes and the voltage stayed constant, no alarms or error messages.
If you have verified the voltage at the inverter terminals under load, it would seem you have a defective inverter. No harm in contacting the manufacturer or supplier for information.
Just for your information, with the four-battery bank, I can power the microwave (132 amps) at 50% SOC with no alarms.
