Greetings all,

Before I post another message asking for help. I'd like to thank all who responded to my recent "solar thermal pumping" question. I appreciate your thoughts.

I just installed a dual inverter system (note to Travis, you could consider a transformer to power a 240 pump rather than dual DR's) and I have a qiustion about getting the battery properly balanced.

I am adding a second SW2512, and as there are no 240 volt loads, I am setting it up as two seperate inverters, each independantly powering approximately half the system loads. There are a couple reasons why I am not using the parallel stacking kit and transformer from Trace (which would solve this problem), but the decision was made to make it seperate inverters on one battery.

I wired the battery cables for the second inverter to the other opposite ends of the battery from the first inverter thinking this would balance the battery, but both sets of negative cables go through the same meter shunt.

It would seem that this this will allow both inverters to draw from just their "ends" of the battery.

I have of course made an attempt to balance the loads between the two inverters which should help to reduce the problem of drawing down one end of the battery more than the other, but is there still a concern? Perhaps both inverters should be wired to the same opposing ends of the battery.

Thanks,

Kurt Nelson
