XW6048 running a 1HP pump? [RE-wrenches]

[Ray Walters]

<x-flowed>

We had an older 1 Hp pump that ran on an SW4024, but NOT on a Outback  
VFX3624.
Funny, because I've run 3 HP pumps on a pair of Outbacks.
So this particular 1 Hp pump surged to over 5000 watts but less than  
7000 (according to the inverter ratings)
THis pump had some issues, but you need to have enough head room to  
handle the pump as it ages.
We fixed this one with a Franklin constant pressure controller that  
acts like the Grundfos SQE (No surge, pump varies rpm to always match  
flow to constant pressure)
It can work with any regular submersible AC pump.
I haven't tried the XW 6048, but it sounds like a monster. I'm pretty  
sure it should handle it,
and if not you switch the controller out. You don't have to pull the  
pump or change the plumbing.
