I believe that the Axpert VM IIs are similar to the PIP-5048MS, except for the MPPT voltage and a few changes to make them economy models. So, presumably similar in ways that are important for fault code 51, "Over current or surge". On the PIP-5048MS (etc) index page, there are five links to posts about that fault code, which might give you some clues. My particular theory (per one of the five sets of posts), is that the MOVs' conduction voltage decreases as they absorb energy, and replacing them might fix the problem. I have links to suitable replacement parts for the PIP-5048MS; with reasonable luck these might be the same parts as in the Axpert VM II.

Are you in a lightning prone area?
