The Discover AES battery 48-48-5120, says it is UL9540 approved. Need some help with a compatible off grid inverter.

I am trying to design a standalone off-grid residential system in southern california using something like four eg4 - 6000xp's and several batteries. The system has to be UL9540 approved here (ul9540A is not enough). The Discover 48V battery says it is ul9540 approved, but I've heard that the eg4-6000Xp's are not. Any suggestions on a compatible Inverter/battery system fully UL9540 approved??? Also, I just noticed that ESS systems installed in utility closets must be under 40KWH to meet UL9540. However, the code seems to allow additional ESS in adjoining areas like a garage. Anybody come accross similar issues with a good solution??

9540 requires the inverter and battery to be listed in combination. I think for example that Discover battery is listed with the XW.

Thank you. Sorry, but did you mean listed with the 6000XP, or some other inverter??

No, he meant with the specific inverter being used, so in his example, only with the XW unless it's been listed with others by now.
