hello
I bought an Openevse terminal from you this month, I already had an old version,
on the terminal that I received, the load shedding function does not work correctly, it does not reduce the power when the power ceiling is exceeded (9000w)
this problem has already been reported by another user, but it has not been taken into account
opened 10:33PM - 09 Nov 23 UTC
I have install the release v5.0.2 on a EVSE with 8.2.3.T2 firmware and Shaper do… es charge current according to my real time house load,
for exemple the maximum power load is set to 8400W:
but the real power load is 9428W. The Shaper set up the charge current to 31,68A for this load which is to high. Charge current decrease only a little with the power load it look like there is a wrong scaling factor in the shaper charge current regulation
If I go back to previous recommanded release v4.2.2 everything work fine exemple:
For comparison release v5.0.2 versus v4.2.2 for the Shaper
You find below the graphic of the recorded shaper charge current regulation, EvSE power usage and house power load. From 22:00 to 22:16 the EVSE was working with release v5.0.2 and after 22:24 the EVSE was working with release v4.2.2
there no current regulation with release v5.0.2 and power load is not limited to 8400W
and after 22:24 the EVSE Shaper is working well with release v4.2.2 with a good current regulation
have you taken into account the problems reported here?
When will they be resolved?
Hi Anthony,
Sorry about this, we’re currently investigating the issue. In the meantime, you can roll back to a previous firmware version.
