Great Stuff Johannes.
Looking good. The board, not your head. !!

Regards and continued success.

WOO HOO!!!!!
Great stuff. I bought a Gen 2 Inverter a couple of weeks ago (£75 delivered ) thinking I would be using Damien's Blue Pill board but This looks like it will be easier to get working.

Hi the Johu, I assume Gen2 Version2 is in process?

[johu]

Yes it is but before reordering I have to discuss with JLC why they twisted the STM32 in the first place. There is a marker on the silk screen and I checked placement when ordering, not sure why they screwed up.

Johannes sent me one of the Gen 2 boards to have a play. So Colonel Kurtz and myself got to work. I think I see why JLC got the stm32 orientation wrong. The designator for C16 is just perfectly overlapping the stm32 footprint corner to make it look like a pin 1 mark!

[johu]

Yes it really does! I hope they don't repeat this in the current order. I did notify them of the mistake though.

[RetroZero]

Such attention to detail Colonel Kurtz, where would you be with out him!

[johu]

Aha, the next batch will arrive here on Monday. Hopefully with the processor aligned correctly.
I think they'll just get a quick optical inspection and power-up test so they can go on the shop sooner.

STOP THE TORTURE !
I would even pre order one to make sure I don't miss out..My precious

The kit includes all connectors (except the 2-pin gate drive power connector)

Great work Johannes. Probably one of the most important developments on here.

[RetroZero]

Thanks Johannes and Damien! ORDERED!
Let the games begin

[Stephen Darbey]

Great stuff Johannes.
Serious news indeed. On my hit list within the next few weeks. I really hope this is the beginning of 'mass production of DIY conversions'

Where are the design files available for the adventurous and/or indigent?

As suggested some new designs will be released for Patrons first and will appear on github with a few months delay.

Fantastic! A Car and control board in the same week, I wonder which will arrive first?

Thank-you for the reply.

Unfortunate though, as it appears the Patreon platform does not allow a Patron to support with cryptocurrency?!
For that matter, one can not buy products from the Openinverter webshop with crypto either.

EDIT: Cash.app supports Bitcoin! I was able to move funds from a ledger, into fiat and onto a virtual debit card to join in supporting. Thought others might find this info useful if they wish to support Openinverter with crypto.

This is not difficult... if you want early access to the designs then support the developers on their chosen platforms

Now, bring this thread back on topic!

Hi theJohannes. The 2 pin power connector you are talking about is the "famous" additional 2 pin white 12V inverter power connector you were looking for?

[johu]

Hi theJohannes. The 2 pin power connector you are talking about is the "famous" additional 2 pin white 12V inverter power connector you were looking for?

Yes. I have now pulled the pins from it and put them into a screw terminal. The offers on the internet may or may not come with pins so I didn't bother.

Now, I fully wired up the inverter to the 12-pole connector with the following results

• Getting good linear DC voltage reading with udcofs=327 and udcgain=3.78
• The current sensors have different gain, the gain of MG2 current sensors is 3.18 and that of the MG1 sensors 6.37. Must somehow be solved in software. Until then the charge input current set point must be doubled.
• I seem to have a faulty buck/boost module. It sings really load when CSDN=12V and the CPWM signal never goes to 15V like the inverter PWM channels. Or am I missing something?

So I couldn't complete my mission to test the battery charging feature. Anyone have a left over buck/boost module (without inductor)? Yes I could just buy another inverter but my space is limited so I'd rather avoid it.

EDIT: whats the temperature curve for the heatsink sensor, anyone got that?
