Most of us with enough experience (scar tissue) using the PRO series schneider products know the firmware is problematic and Schneider managed to build in a laundry list of issues that the plus series never had. That being said, although Shneider PRO product firmware is an easy target. I would definitely check the wiring first. Particularly with DIY installations improper Ground and neutral connections are a common cause for the failures you are describing. Personally, I have had my share of problems with the PRO series Scheider products, but have never seen any equipment damage. I have however seen numerous instances of installer error particularly with the previously mentioned Neutral and ground circuits. Common mistakes are multiple Neutral to ground bonding points rather than just one and only one. Improperly or undersized, or even missing Neutral conductors. I have even seen a "hot" wire used as a neutral, and shockingly the 120 Volt devices that were being supplied with 240 Volts managed to survive for a few weeks. For sure check all the onsite wiring before diving into inverter firmware issues.

Kevin, Can you elaborate on some of the issues you’ve sen with XW Pro off grid and with the >V2.04 firmware versions? I have a few XW Pro units out there fully off-grid running newer firmware and I haven’t had any trouble— yet.

Bad wiring can cause issues, but if it’s actually letting the smoke out of electronics, pretty high chance it’s the bad firmware that Schneider knows all about but refused to address. If it’s got 2.04 firmware get rid of it. Downgrade to 1.11. It’s the only stable software for that system IMO. https://www.se.com/us/en/product-range/66297-xw-pro/#software-and-firmware My only other comment is I am seeing best client satisfaction by un-installing anything Scheider made post 2019 and replacing it with a better brand that just works reliably and consistently.

This system was installed by neighbors so it may be a wiring problem but I also wonder if it may have the bad firmware that was doing this (generator interaction was the problem I think). Can anyone remind me of the proper firmware that we should run for an off-grid system with the XW Pro? How to get it? And any other nuances that I should be aware of?
