GE - EV charger setup

Hi All,

I am having a GE EV charger fitted next week. I have done some homework and have a question as it’s not clear in any documentation on GE site and the App documentation is still on 2022.

I have an AIO and Gateway, the EV will be plugged into the Gateway via a RCBO Type A and a GEM120 Meter.

This is the first question in the app :-

Choose a Configuration A, B, C, D, E (coming soon). I am thinking D but C also looks like an option. (No reply from GE yet). I don’t want to pick the wrong one and then can not change it later or have to reset it etc. Anyone else done this yet?

Which

recently installed and found the commissioning a bit of a faff. I dont have the meter so went for option D (inverter control). Kept messing around with my battery charge rate and a few other things, so changed to option C (no integration). Works fine now with grid charging now. you can change configuration at anytime easy enough. i might try option D at another time.

Thank you for letting me know I can change it later.

Daveb01 out of interest ive recently created some python script that runs on the raspberry pi that can adjust charging using GE cloud API. works brilliantly. When my home battery gets over 75% it sets the EVC to solar mode and when above 90% sets it to Hybrid mode.

G-dog That's amazing! Could you share your script please?

I'd like to create a script to turn on and off battery charging, depending on solar production levels. I am comfortable reading things via API, but not got around writing, yet!

This is a result of a script I wrote, read only notifications in Telegram:

bRhFDKtjRMK9 The API facility is very handy. Ill did out the script n attach share

bRhFDKtjRMK9 Wont allow upload so heres a link to folder with scripts. put all the scripts in same folder and amend script for your inverter/EVC API keys, inverter serial numbers/EVC UUID. and modify away

The "GE_write_charge_rate.py" script does the API writing bit to set the inverter charge rate again at end of day.

The "GE_EVC_Inverter_Control.py" script writes to EVC to change charging mode. I have set it up to return the EVC to standalone mode at the end of day as otherwise it seems to mess up inverter for some other scripts i have that manage the inverter.

BTW dont judge my coding skills lol
