EG4 XP 6000 trips

[Kennlee]

I have a 1.5HP 240v well pump that draws 12.7a on L1 and 12.2 on L2 with start up of 28.3 amps, my EG4 XP 6000 won't start it. Would installing a soft start help or am I doing something wrong?

I would think that pump would require up to 5x of running current to start up unless it is a special or augmented pump. This is why people put soft starters on their HVAC. I haven't tried one on a well pump yet. I have tried a Solar Pump Inverter on a capacitor start pool pump and it ramped it up by PWM. Get a inrush current or stalled stator current meter to see the peek Amps.

I can and do run it on a 5000watt generator and the xp6000 is rated to 10k watts for 30 seconds, I fail to understand why the 6000 won't start it and the generator will, the generator is actually smaller than the 6000

My Predator 6500 can start start pump up just fine but a mechanical generator has all that weight/mass spinning with a lot of inertia that helps it get through the peek. Inverter will fault out as soon as you hit that peek.

3-wire pump? Finding the control box next to your pressure tank is the easiest way to tell.

That 1.5hp pump probably has a inrush current closer to 4X it's running current.

There's no "soft start" for a submersible well pump, certainly not a readily available one. Some say there is but I have my doubts.

What is your battery capacity and how is it wired to the XP?

What was the battery capacity and PV input when trying to run the well pump? Also, would you be able to measure the startup current when trying to power this?

@Kennlee Any update on this?
