Wayne,I'd recommend against that. To do an effective equalization charge on that bank you'll need to get the voltage up to at least 2.6-2.7V per cell. That would mean a 13 cell pack voltage of 34-35V. Got any DC loads at all? Danger, Will Robinson, Danger!  Using the inverter as a charging source? I think you'll run out of transformer windings or at the very least reduce your amperage output greatly toward the end of that cycle.Hopefully, Jamie can jump in with an opinion here as well.Good Luck!Bob-O
