Hi just wanted to confirm if anyone is currently successfully integration with the Delta AC Max Smart via OCPP? I ask because I heard (second hand information) that Delta says this is not currently the case and waiting on a ‘firmware upgrade’.
Thanks in advance.
There are many Delta AC Max units being used successfully with Charge HQ.
Testing suggests there are major problems with the latest firmware V01.26.34.00 and it doesn’t work with Charge HQ. All other firmware versions should be okay.
Previous firmware versions are available here: AC MAX Smart AC Charger Firmware Library – Delta Support. We haven’t tested a firmware downgrade - if anyone can confirm that works that would be great.
