DC 80V to 15V HV Buck DC-DC Converter I didn't see any footprint on the MPPT, different board? I also use the same supply on my MPPT controllers. I fitted plugs and sockets so they can be swapped out easily. I managed to blow up a few early on until I learned you shouldn't power down an MPPT without first shutting off the solar input. I bought some of the regulator ICs off ebay and fixed them up. I know they're cheap and I have spares  ...  but I hate loose ends.
