Time settings on inverter
Once the system connection to the server is off line the time setting go out.
This results that the charging and discharging settings on the inverter not working properly.
Is it normal or is there a way to avoid it ?

Hi, I just installed my 8kW Ecco, I have to say its awesome so far, 3 days in. Powertrain is perfect.
But I noticed that the inverter's clock gains time roughly 20 mins per 4 hours (5m/hr). I appreciate that the WiFi logger keeps the time sync'd via NTP protocol or similar but I wanted to understand why the inverter cannot keep time for itself? Is this a known hardware limitation or issue when not connected? My old Growatt suffered this issue also, although not as extreme as 5m/h, and I sync'd with NTP.
The Real Time Clock Calender (RTCC) may have a low cost 32.768kHz crystal, (or none at all) or incorrect load capacitors, or perhaps extreme temps are causing tolerance issues, perhaps it just needs calibrating.
Either way if its expected, then I'll manage it, but if there is a firmware fix can you let me know if I need it.

Much appreciated.
Update: I added a video of 1 min of clock on inverter, and you can see we are 10 seconds out over 1min, that's really not good,
