question

I have a system just like what you describe. I have a Phoenix Smart Charger IP43 to charge a battery and then a cute little Phoenix Inverter 375VA to power a network switch and a HPE DL380 G8. There is also a BMV-600 for the battery monitor for the 100Ah lithium battery bank.
It all works really well.

You do not see AC consumption from the charger. I would not think this is a bug though. More likely due to the fact that the chargers don't have AC sensors, so the information simply isn't available in the first place. This does not affect the functionality of the system though and your idea of an online UPS system should work just fine, like mine does.

On VRM it looks like that:

Hi, and thank you for your answer.

Your situation is the same as I previously read in another thread. You have a "Phonix Smart" charger, which AFAIK has VE-Connect only.

I'd like to know if situation is identical with "Phoenix 12/30", which has VE-Bus.

In other words, is the missing AC source information caused by the lack of VE-Bus on your charger model, or is it caused by the fact we are using a sdandalone charger (whether it's VE-Bus or VE-Connect) ?

You say it's not a bug. In Microsoft words, that could be considered as a "lack of feature" :-D But for me, it's clearly a "blocking" thing. What's the purpose of having full-teatured communication buses, network and cloud, if information is not available on them ? Moreover, I'll also sink some DC current directly. This is supported via the "Has DC system" setting in the menu. It's calculated by the difference between what the charger measures and what the BVM measures. If the charger does not provide data, then the measured DC would not be displayed, too. I wouldn't spend 2000 € (and 500 € just for the graphical display) for something that will not display data correctly...

If the AC source is not displayed in GX or VRM, I'd like to know if the information is technically available somewhere at lower level : does the charger VE-Bus deliver this information directly to the bus, or to any other "developer" tool, such as API, MQTT, etc ?

(But maybe this isn not the right place for that question. Is there some dedicated forum or mailing-list targeted to developers ?)

Kind regards

You can add a smartshunt configured as DC meter, subtype solar charger, to the negative wire from the charger. Connected via ve.direct, this will then show your charging power on vrm.

Sadly, no other integration of charging sources into vrm is possible but this works perfectly. Only downside is the term "solar sharger", however i am using this with a Alternator ti Battery charger in my RV for quite a while now and technically its perfect.
