I'm looking at creating a battery bank capable of powering a large inductive load, specifically a 3hp well pump for which I've measured an inrush current of 55A at 240v. These low frequency inverter chargers are described as being well suited for such a load and can surge up to 18,000W for 20 seconds.
Can I pair one of these inverters with 4 (or more) EG4 batteries to handle such a load? The batteries are rated for 100A discharge which would be 19,200W. Would the batteries be able to handle such a surge/inrush? I've read other threads (here) which suggests that a surge of >30A causes issues, but I haven't been able to find any other info to back that up.
I suppose if I filled out a full rack of 6 batteries, that would drop it to 45A per battery which is still above that 30A figure. An alternative is the SOK battery whose manual states a "Peak Discharge Current: 125A (3 Seconds, automatic shutdown)". Can I assume this 125A figure to be valid for an inrush / surge load?
My plan would be to purchase as follows, though I don't know if there's a reason to prefer one hardware over the other:
But my main concerns is still about the batteries and how they respond to a large inductive load.
I appreciate the time and help, thanks!

- 6000W 48V Inverter Charger - one of:
- AIMS - $2,244 or
- Sigineer - $1,349 or
- SunGoldPower - $1,299
- 48V 100AH battery:
- 30.72kWh EG4-LifePower4 Kit - $8,694
- 25kWh SOK Kit - $8,450
But my main concerns is still about the batteries and how they respond to a large inductive load.
