1 x MP5000/48
1 x CCGX
1 x 250/100 MPPT
4 x BYD B-Box 2.5kWh
We have two issues on the site.
1. First is with the new firmware (post 2.13) the CCGX seems to lose communications with the BYD BMS. The voltage is shown as 0V and 0A on the CCGX. After a short while, it all comes back online again (as in the image below). Swopped out the CCGX with a new unit but it does not resolve the issue. Rolled back to fimrware version 2.13 and the issue is gone. Any help on how to resolve this?
2. The second issue is the PV throttles even though grid feed is allowed. No cloud cover, DVCC on/off (on 2.20+) makes no difference. There is no shading from Clouds, birds and the panels are clean. Any help in this matter would be great.
