AC200MAX AC and DC on/off not working

I recently bought a second AC200MAX. When I switched it on for the 1st time, the “AC on” and “DC On” functions on the screen do not work. (This seems like a common issue) However, neither do the DC and AC functions work through the app. Everything else seems to work (through screen or app). I upgraded the firmware, but that did not fix it.
SN: 2317000227993
DSP version 4005.08
ARM version 2040.04
BMS version 1017.03
HMI version 6045.02

The original AC200MAX (the one that works fine) strangely has different firmware, although I updated both and both say they are up to date?
The working unit’s details are:
SN: 2314000006986
DSP version 4005.08
ARM version 4008.05
BMS version 1017.03
HMI version 6037.05

Anybody have a trick to fix it?

Hi @svonarx, I think this problem can be resolved by upgrading the new firmware.
We have already applied to push a new firmware for you.
Our IT department will push the latest version of firmware to your machine in 24 hours. Please upgrade it tomorrow.
Please do not load any device when upgrading it.
Please let us know if it works.

By the way, different batches of machines may have varying firmware versions, which might not be compatible for mutual upgrades. This is normal.

Hi @svonarx, Our engineers have informed me that your machine is a Paygo version, which prevents us from pushing new firmware.
Could you please let us know where you purchased it, whether it was a full payment, and what your Paygo ID is?

If you haven’t renewed your subscription, please do so first. If you have fully purchased it, please contact customer service for further assistance.
