They also do not accept AC input when in parallel mode (the AC input sign just flashes with no error code). When in single mode, the same AC input works just fine.
Interesting. But those don't sound like bugs that later firmware can fix, since older PIPs did not behave like that.
The firmware is
52.30. According to the
decision tree it is tantamount to 72 "
Else if the current firmware minor version is less than 40 then". However, I am not too sure that I have "
5 kW (PF1) model with the 64 V option" as that entry says.
You certainly do not have PF1, and not the 64 V option either. I could not imagine how you came to that conclusion, until I "executed" the decision tree with the parameter "52.30" myself. I see I had a bug in my logic

Fixed now. In short, you could try 72.70c or really you may as well go to 73.00e. You even have the luxury of reverting back to
factory firmware version 52.30, if it doesn't work. But as above, I don't expect it to fix your main problems, unfortunately. They seem to be rooted in imperfect copies of the hardware.
It's also entirely possible that you can't update anything at all. You may have early versions of the clones that later came with patched firmware 72.70c (lead acid flavour), but could not update firmware because they don't have a bootstrap loader. Both of these clones have the "¢" (cent) symbol in place of the "Φ" (Greek letter Phi symbol), so I'm guessing that they may be from the same factory and therefore have similar limitations.
Edit: actually, updating the firmware (if that's even possible) might fix the AC input problem, since the early versions did have a lot of problems with generators (another AC-in source), and they are less picky in later firmware versions (but far from forgiving of many generators, especially generators that aren't inverter based).
