I recently built a three phase OpenEVSE unit. I used the US supplied advanced kit and added a 240V 2 pole contactor. So the original contactor is used for L1 and neutral and the other phases L2,L3 go through the new (Din mounted) contactor. I also added a 3 phase RCD and have kept the GCFI even though it is a bit of a duplication. I purchased a bigger box and mounted a Mennekes 63A socket on it. Input is a relatively short and sturdy 63A 5 core cable with three phase plug. I have interfaced to Emoncms on my own server.
Now I am trying to figure out what is the best firmware to use and I am sure someone here will have an idea. I am in Australia where things are pretty much the same as in Europe.
I started with the 4.8 firmware and currently have the 5.0.0.EU software. Things have been very muddled with 4.8 multiplying the power by 3 (good) for three phase but also for single phase Type 2 (bad). 5.00 does not seem to do any multiplication.
Basically, what I would like is as follows (and perhaps someone could explain if this is the purpose of 3ph-emonopenevse.hex 5.0.0?)
-
If set to type 1, OpenEVSE to use 230V and the measured current for displayed values and to upload to emoncms.
-
If set to Type 2, detects if single or three phase and multiplies power by three (only if 3ph) for display, storage and upload to emoncms.
So, I think I am best with 3ph-emonopenevse firmware. Is that true and does it work as I have indicated?
Thanks,
