DVCC on Raspberry Pi

Hi there.

I have Venus running great on my Raspberry Pi 3. I have 3 x MPPT connected via USB Ve.Direct to the Pi as well as a Multiplus and SmartShunt. They charge a bank of lead acid batts.

After enabling DVCC on the Venus, is there a way to verify its working as expected? The reason I ask is when I go to Network Status on the MPPTs, it states:

- Networked = No

- Status = Standalone

- BMS = No

This status doesn’t seem to indicate that DVCC is working as you’d expect the device to think it was networked.

The alternative is I use VE Smart Network which I have used with success previously but don’t see why DVCC isn’t working.

Thanks

IIRC, when I had only DVCC and not ESS enabled, there was no indication the MPPT were under external control or networked in anyway.


Use DVCC to set a low charge current limit. If they observe that limit, you know it's working.

The MPPT's only run networked via V.E Can I believe.


Setting, System Setup, System Status is where you can see DVCC status

Thanks. Is that a screenshot from Venus on a Pi? I don't have a menu option for "system status"
