Pheonix Inverter Statistics

Hi there,

I have a Phoenix 24/500 ve.direct inverter. I am using it with the venus firmware on a raspberry pi. I also have a SmartSolar 100/20 and a BMV 712.

In the VRM Portal, the statistics for the inverter are incorrect... It correctly shows the voltage operating at 230v, but the current hovers between 0 and -0.4 amps... they never seem to reach into the positive...

On the venus device, the stats also show 230v, 0 amps, 0 watts... occasionally the watts will flick to 25 or 50w, but only very briefly.

I know I am drawing about 150w through it (according to the BMV-712)

I read a post that was around 9 months old, saying that the stats for inverters over ve.direct was still in development. Is this still the case? It's curious that I get the correct voltage, but not the correct current...

I also seem unable to adjust all the settings for the Phoenix on the Venus interface... for example, adjusting the low voltage shutdown. Is this expected?

Many thanks! :-D

Hi Samatch,

The power reading on the ve.direct inverters is not very accurate. Unfortunately this is the way that it is. There was a previous post about it here. This is a hardware limitation.


For now, adjusting the other parameters (eg low voltage shutdown) from their defaults requires VictronConnect, and a VE.direct to bluetooth adapter, or VE.direct to USB adaptor depending on your device.


The power reading from your BMV should provide a very accurate figure for what is being transacted from the batteries. Though it will not be inclusive of the solar, it is possible to get a good idea of the overall flow of the system if all devices are connected to the GX device.

Hey Guy,

Thanks for responding, much appreciated.

Disappointing that the statistics are not available / accurate. I'm curious as to what the limitation here is? Is it just a question of Victron not having included an appropriate measuring device on the outbound AC or something? Seems a shame for an inverter that I didn't think was at the cheaper end of the market...

At the moment I can see the DC load stats through the GX device (raspberry pi Venus), which also includes the inverter. Ultimately I'm just playing around with this equipment, it was a nice have to have. A shame I can't have it! :-)
