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...

Hi Marc,
Are you already running the largest wire that will fit the terminals in the inverter? Is there any possible way to shorten the path?
What size is the interconnect (series) cable on the battery bank? It should be larger than the wire to the inverter.
Check to see that all connections are clean and tight. A couple of copper or brass washers on each post might increase the contact area for the cables.
Anti corrosion spray is your friend.
When the prowatt is running, what is the output voltage with a tiny load on it? What is the output voltage when pushing the inverter "to the edge"?
Remember that when the prowatt is running flat out, it is asking each cell to produce 474 amps of Peukert corrected instant power. That really is pushing the bank hard.
Options for next fall:
Buy four new six volt golf cart batteries. That will drop the Peukert corrected load to 193 amps per cell
-or-
Buy two group 29 twelve volt batteries and wire them in a balanced manner. That will drop the Peukert corrected amps to 230 amps per cell.
-or-
Buy four group 29 twelve volt batteries and wire them in a balanced manner. That will drop the Peukert corrected amps to about 94 amps per cell.
