Re: Tesla Charger alternative firmware
230Vac 3phase. I have a solar PV netmetering plant which can drive the voltage from 228Vac to 243Vac when full power.

Re: Tesla Charger alternative firmware
Charger reports 160Volts AC 50Hz.
I will recheck.
Some times I see 190 and 230.

Re: Tesla Charger alternative firmware
Phase 3 I checked. What i see is that error flag gets raised.
Or am I looking at the wrong module?

Do you think i could get better resilts if i disconnect 3rd phase and 1st and 2nd would increase their output?EV_Builder wrote: ↑Wed Aug 17, 2022 8:35 am Phase 3 I checked. What i see is that error flag gets raised.

Re: Tesla Charger alternative firmware
Not really better if you'll always have one module off. Still minus 3.3 kw. But you can try and see if one module is indeed a problem.

Re: Tesla Charger alternative firmware
It depends; do you measure the same? Do you have small capacity connection somehow?
Always good to start with one module full swing and then scale up.

Re: Tesla Charger alternative firmware
@johu, do you agree about that time delay issue, and can you make a new release to solve it?
Also do you think will implement the additional couple of CAN parameters I asked for in PM - I think this will make it fully usable as a "slave" for a charge controller.
Thanks!

Re: Tesla Charger alternative firmware
OK, I don't want to keep bugging johu because it's been 2 months and several messages here, DM and email without any answer at all - I understand everyone's busy!
The request was a small bug fix, and a minor feature to add. This is the commercial / supported firmware, that's why we've been waiting, but would have understood "no" so that we could move on.
To be clear, the original release works fine if you can work with the features it supports.

Re: Tesla Charger alternative firmware
This was the request, an additional CANBUS parameter:
"I would like to be able to set iaclim. Per 1 amp would be fine, so a single byte. It would be nice to see feedback of module AC current too, and 3-phase status, but not critical."
This was an attempt to get the charger to work behind a charge controller which manages the combo port (it takes the PP and CP connections), and deals with AC or DC charging. It has *almost* everything it needs, but obviously passing through the cable and EVSE limit is an important one.

Re: Tesla Charger alternative firmware
No.
I think I'll rather make the firmware public so someone else can maintain it. More to come.

Re: Tesla Charger alternative firmware
Wicked!
Had a browse just then and it should be easy to modify for the community and add features.
What a great contribution, I like how short it is, only 1037 lines in src/*.

Please do! Hopefully others can contribute the features they want! It doesn't always work this way, but we can hope!

Re: Tesla Charger alternative firmware
Gonna get stage fright here!
I just sent you an update, with my changes, let me know if you want more cleanup done as I just quickly whacked my test-"framework" in and tested ~200 LOC of primitives and left some stubs in case someone else has time to flesh it out more.
Hope it meets the standard!

Audi and foc keeps me from getting back to this, will publish the code on github soon including Janoshes test suite.

Re: Tesla Charger alternative firmware
Having an issue right now where my gen 2 Tesla OBC with the latest firmware from Patreon. The parameters do not save on a power cycle. The charger works but I need to manually set parameters every time I turn it on via the web interface. Does anyone know a workaround?
I'm thinking about compiling a version of firmware to upload to the charger that auto-sets type 1 and turns timdly to default at 0 not -1.
I cant get the code to compline in cube though. It's weirdly greyed out.
Thanks in advance.
EDIT FIXED: I was using a 2019 Macbook pro bootcamped (running windows 10 pro) to connect to the ESP8266. Apparently drivers are really janky for the broadcom wifi onboard in windows since I tried setting parameters with another device and it quite literally just worked. If anyone wants a fix for a macbook pro bootcamped I rolled back my drivers in device manager and it seemed to let me control via the web interface now and save parameters successfully!
I Hope this helps someone

Re: Tesla Charger alternative firmware
I'm about to buy Tesla Gen 3 charger, interested in 3 phase unit, compatible with this software.
Wiki page for Tesla Model S/X GEN3 Charger (https://openinverter.org/wiki/Tesla_Mod ... N3_Charger) lists just one P/N 103564701C
I seem to be able to get P/N 1055139-01-B unit - it's got four orange power cables going in, on its label it says "KIT:X-EU" then "KIT, GEN3 CHRG SYS, 3PH EU EMC, M...", so I expect it is a 3phase unit with 3 modules inside? it's got a big "3" on it, where often I saw similar-size sticker with current rating (e.g. 48A/72A) but this one doesn't seem to have any sticker with number related to current rating.
I have also P/N 1055139-02-A and this is 48A (two modules inside) working with current software.
If anyone could confirm 1055139-01-B is a 21kW with 3 modules inside would be great. Thank you.

Re: Tesla Charger alternative firmware
Hi, all gen3 charger versions will work with this firmware. However none of the gen3 chargers is 22 kw. The one with 2 modules is ~12 kw, the one with 3 modules is ~17kw. I have both versions for sale at good prices, PM if interested
