Stacking Two Schneider Electric SW-4048 Inverters Failure

I recently installed two Schneider SW4048 inverters and their stacking kit. Configured one as master and the other as slave. The system ran perfectly except when I decided to power down the system for some maintenance. I started the system per their instructions and I heard a loud clunk from one inverter and it threw an error code that the Master inverter failed. I attempted to restart the inverter and it was dead.
I then contacted Schneider Solar tech support to get a replacement inverter since it was less than two months old and under warranty. Surprisingly I was informed that Schneider pulled their inverter stacking kit off the market and they are now telling me that they can't be stacked. Although they still say stacking is acceptable in their current literature. Am I being hoodwinked by them or what? They said run them separately or nothing and they can't even share a common battery bank even if the outputs were separate.
Is anyone running these inverters in parallel? And is it successful? I would caution anyone who purchases two of these inverters and want to stack them to ask questions. I am now stuck with my purchase and my only option is to go with an XW+6848 inverter or abandon Schneider altogether. I will be stuck with their switchgear and other support equipment if I decide to do this.....any info appreciated. Thank you....
