Yes, and I believe that OzDIY / Suzi Auto carry ones that look identical.

Excellent quality, the Rolls Royce of chargers, but might be a lot more expensive again, I haven't checked lately.

Re: PIP-4048MS and PIP-5048MS inverters

can we get the voltage up to 66v for charging ... There are other problems. The main one is that the bus voltage is mostly tied to a multiple of the battery voltage; for the 58.4 V models it was 8:1 (I assume that they use a smaller ratio for the 64 V models). So 66 V would push the bus voltage too...

They do have the solar charging bug mentioned earlier in this thread (reported power appears to be twice as much lower until you turn PV off and back on). 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 inp...

Ah. More than a "few" voice coils. And lots of fans to cool them.

And competition for the most outrageous, rather than a usable system for actual listening. I guess it's a hobby. A very expensive one, I suspect.

Re: Parallel Inverters - Fault Code 60

Not sure I understand this. How does the inverter get to such a high negative battery value? The power has to come from the other output. I've just realised that fault code 60 (error 60) only comes up when in battery mode. When charging from utility, you have to be in line mode (shows "BYPASS" on t...

Re: PIP Inverter Error "error 09" bus soft start failed

it should be a transformer seemingly with the data ( TX 15:200:15 FER EEL16 ) Transformers are not usually stock parts. It's actually a Multi-winding inductor, i.e. it has an air gap for storing energy; the power supply is a flyback type. The 15:200:15 part might be the turns ratio, possibly even t...

We'd like to. But first, we have to get hold of some firmware to patch.

Unless of course, lightning strikes :idea: and the manufacturer fixes at least the premature float bugs.
