    Hi, I have RCT V2 inverters some have firmware U1 52 20  and now I got an odd U1 52 32. Can you help me with any compatible firmware please? As you kindly always do.

      Looks like I never got the time to thoroughly analyse the difference between 52.29 and 52.31. I now strongly suspect that 52.31 is the later of these two, though apparently one minor revision older than your odd inverter.

      My suggestion is to update the two older inverters to 52.31, the second of the two firmwares at this post:

      Thank you so so much, you're very helpful as always. I've successfully down graded the 52 32 inverter to 52 31 and then upgraded the one next to it from 52 20 also to 52 31 and now they are happily paralleled in electronic matrimony😂

      Keep up the good work.

      Best wishes.
