The question is: Can a Tri-Star 45 in Custom mode be programmed for a SimpliPhi 48? As in no absorb time (<.1-.2 hr), EQ off, 55vdc max absorb, etc?

Our water well lead battery bank is end of life so I just plugged the Grundfos into the house 120vac system. But if we lost house power we lose the water well after the pressure tanks run down. I designed the project originally to have two systems so we never lost water. As these batteries wind down and an draw on the main system I am rethinking this combination.

I went with SimpliPhi 3.8-48 for the house two years ago. Love 'em. But one block is way too big for the water well not to mention the expense - at 48vdc it draws 800 watts during run time.

What would you do other than a separate generator at the well?

    I definitely have to take some action soon. I'm looking at this battery: https://alliedlithium.com/products/allied-lithium-48v-x-30ah-batteries

    It's promoted as a drop in replacement for a lead golf cart battery. Also looks like the Tri-Star MPPT 45 built in profile for a Gel battery would work fine with the Allied 30ah battery.
