[RE-wrenches] Solar/Batt Well Pump Recommendation Request

[Jason Szumlanski]

I have a customer with an existing grid-tied PV system with battery
backup (24Vdc). The inverter feeds a (120V only) critical load subpanel.
He has a 240V well pump with 85' total lift and a 4" well. Originally he
came to me looking for a PV direct solar well pump. Immediately I
thought about just using a step-up transformer to handle the 240V well
pump on his existing system, saving a lot of cost (he does not need
additional PV to handle the pump load and the inverter is capable of
running the pump). Now I think the better solution is to get him a DC
well pump to run directly off his existing battery bank. I would just
need to add a LVD. If he wants to add more solar, we can tackle that
separately. 

 

Any thoughts on my approach, and anyone with a recommended pump model
off the top of their head?
