I haven't seen much out there on the Schneider SW4024 recently so I thought I would share my initial impressions after getting it installed. My primary reason (as usual) for a split phase inverter was to be able to start my well pump. This inverter is rated at 3400W continuous but 7000W for a 5 second surge, which I hoped would be adequate, but it's hard to accurately measure the surge current required to start a motor. The pump is a 3/4HP which draws roughly 1500W continuous, but measurements of the inrush current with a clamp meter were all over the place, from 8 A to 27A, the clamp meter is simply not fast enough.
After installation I was happy to discover that this unit had no problems starting the well pump, although at start up it did pull a massive amount of current from the batteries. I'm using 24V 280Ah home built battery (EVE cells) with two separate JBD BMSs, the maximum long duration current on these is 120A, fortunately the surge on the well pump was short enough to not trip the overcurrent protection.
The Schneider is not the cheapest option - to the base price you need to add a connection box of some kind which adds about $300 to the cost. Best option for control is the Schneider Insight Gateway, which in spite of some poor reviews seems to work fine, with both the web connect app and mobile app. The optional DC switchgear (added box on the left below) adds a convenient place for the DC breakers but not much else.
Will post more as I learn more about it.
