I have gotten hold of a Gen3 inverter and I'm looking to try to interface with it. There seem to be a lot of projects around that do this, but unfortunately none of them have much in the way of documentation so I haven't been able to find out much about the inverter itself.
Does anyone know if there is documentation on the inverter pinout, what each signal is for and how it's used? I can see that some of this information can be gleaned from the Toyota wiring diagram and repair manual, but it's not exactly in an easy-to-follow format. I was thinking of starting a page on the OpenInverter wiki documenting what all the connectors and pins are for, but I didn't want to start this if someone already has this information hidden away somewhere and is willing to share.
I've looked in the following places:
- Toyota Prius Gen3 Board page on the wiki - seems to be about a replacement board rather than the inverter itself. It contains a pinout but the connector shown doesn't match the inverter I have so it must be a connector specific to the replacement board and nothing to do with the inverter itself.
- ZombieVerter VCU page on the wiki - claims it supports the Prius Gen3 inverter but has no information on how to connect it up
- Toyota Inverters on the wiki - seems to contain what I'm after but the introduction promises "wiring and connector information" but this doesn't seem to have made it to the page yet. There is one image with pin descriptions for the Prius Gen3 inverter though which is a start for me. I'm not sure what the "Toyota Protocol" section is for as it sounds intriguing but doesn't really explain much.
- Toyota Auris/Yaris Inverter page on the wiki - the above page links to this one claiming it has connector information, but it seems to be more about a replacement control board for the inverter rather than a page about the inverter itself
- A bunch of forum threads but these are very difficult to use for reference information as the discussion topic varies wildly so you have to read through 10 pages of posts only to find the information you thought would be there isn't!
