Hello,
I am running 2 Marstek B2500D units. Originally, both should have worked with a Shelly Pro 3EM, but unfortunately the batteries do not detect the Shelly correctly.
As a workaround, I installed b2500meter in Home Assistant. In the beginning, everything seemed to work fine. But after around 2 days, only one storage unit continued feeding power, while the second one stopped completely.
To fix it, I opened the PowerZero app, briefly switched the inverter to manual mode, and the unit started feeding power again immediately. After that, I switched it back to automatic mode.
The same issue happened again today:
Battery 1 was feeding in normally
Battery 2 was inactive
Only after manually setting the feed-in again in the app did Battery 2 resume operation
My question is:
Is this likely caused by my current configuration?
Or are other users seeing the same behavior with multiple B2500D units?
Environment:
2x Marstek B2500D
Shelly Pro 3EM
Home Assistant
b2500meter integration
I can provide additional details, logs, or configuration if required.
