Hello fellow Victron enthusiasts.
Me again with another question from the field. As we installed a few devices lately we encounter quite a lot of issues. Two customers now report that the screen on the EV Chrager just freezes up randomly and only solution is to turn of AC power for few minutes and restart. One of them even says the display looks like two displays into one, on frozen and one overlayed. Before I drive 200km thought I will ask here.
As a side story to get a grasp on whole situation how much it costs a company having a product with poor Q&A and how much time and frustration from customer end:
This customer was sold a premium Victron system instead of a Huawei setup (which our company has three times more deployments and zero issues of this kind reported).
The original setup:
3 x Multi II 3KVA
Cerbo GX
MPPT 250/100 & 250/60
EV Charging station on AC out
Pytes 5kw LIFEPO4
1. On day of installation we noticed the LED ring on the EV charging station was not lighting up. Local dealer had no idea what is going on and sent a replacement which had the LED ring work but display was frozen. Yet another 3rd device was sent (already 3rd customer visit) which had same LED ring issues as the first. Thanks to this community and Guy we were told to upgrade the device and LED ring issue got resolved. (we ignored the frozen screen with the second unit - comes back to bite us later)
2. Not long after this the user called us one of the MPPT's is not working. We went out and found the 250/100 unit was dead. Replaced under warranty and dealer reported it was a hardware fault.
3. Customer now called and reported the new MPPT installed never reaches the same levels of PV power like the one before. We could somewhat agree with customer from stats between the two devices. Decission was taken to replace the solar chargers with a RS 450/200 because of so many visits already.
4. After this we notice that the grid feed-in is up and down about which I posted here and got a response to upgrade the Pytes firmware as it is a known issue. (8th visit!)
5. Now we still have an issues where the EV Charging station just freezes up randomly and customer is really pissed off with Victron setup.
The firware is the latest as can be observed: 
Has anyone else run into this issue recently?
