Very nice! The Kostal is even a very good Tip, with it's combined PV/Batt Input this could even Work for my EV6 with Up to 825V.

Currently I've stopped my Tests, because of some "incident". A Capacitor is blown... Luckily nothing Else Happens. Bit Always remember: High DC voltage is Dangerous!

In ...

Short Update:
I always get over PreCharging, even without Inverter. The Inverter doesn't even provide voltage. That might be the issue. I guess the Inverter is too slow. Would be interesting, if we could extend the PreCharging time, by very slowly increasing simulated voltage. At least 1min might be ...

...just re-read the previous posts. There is a description, that during PreCharge a voltage is required. This seems to be fulfilled by the inverter. But with voltages which requires the dc/dc converter (<800V) there seem to be a timeout of 10s. This might be an indication that here maybe only ...

I was able to re-establish connection only after disconnecting CP, then quit pyPlc, close eth0 (down) and open again (up), then start pyPlc.py -E and connect CP again. With this it's nearly always starting communication completely and not only to SDP2.

I've connected vehicle to Sungrow SH8.0RT and ...

Since hybrid inverters have battery voltage maximum of 600V, I've put this into the settings. UTarget is now 540V - so maybe the buck/boost converter can handle different voltage levels in some steps. Looks quite good.

I think it's time to get a hybrid inverter...

Retested with original settings: EVSEMaximumVoltage 450V -> gives 405V to the DC port for 10sec
recompilation with 1000V -> gives 390V to the DC port for 10sec

Seems the car needs some external voltage to activate port permanently. EVSE output looks a bit different. With 1000V the car has UTarget ...

Ok, thanks for quick Response. Will try this evening.
Step down seems to work, If EVSE voltage readings are correct. They were slowly ramping Up, so looked Like real meaurements. I can Check with Multimeter later. Only question would be, If Power or how much Power could be transferred "downwards". I ...

Hello,
just trying to build up a DC Wallbox and I'm very happy how cool this forum is.

Currently trying with a Kia EV6 to activate DC port.
At first I was struggling with starting the communication at all. For now it looks like, after applying +12V to CP, I'll have to wait 6sec before switching to ...
