Adding an Outback Radian Inverter GS8048A to a GS8048-01

I purchased a new GS8048A to parallel connect to my existing GS8048-01 to double my amperage output. After doing this, I was unable to sync my two inverters because the software/firmware was incompatible between the two. OUCH!! I wished I had know this up front! With this in mind, I have a couple of options to resolve the problem:
1. Sell the new GS8048A.
2. Swap the new GS8048A for an GS8048-01 in good working order.
3. Buy a used GS8048-01 in good working order and remove its control PC module and swap it into the new GS8048A.
