Hi Kit,

PV voltage is available in the Advanced section of VRM, enable the PV voltage widget.

thanks mate for your reply, as it turns out i have the PV V & A widget turned on and all it has in it is no data to display.

I have 3 bluesolar 100/85 chargers that a hooked together , this should'nt effect the data ?

thanks

Hi Kit,

Please update the firmware on the VE.Can MPPT's to the latest version - https://www.victronenergy.com/live/vrm_portal:remote-firmware-update

If that still doesn't work, let me know and I will follow up with the VRM developers and get a definitely ruling, perhaps there is a limitation with that feature in your configuration.

EDIT - Looking through the reported dataset for the VE.Can MPPT's, I cannot see a solar voltage figure reported or recorded. Sorry, I will still ask but it doesn't seem possible with those units.

hi

when you scroll manually on the charger , the pv max volts show,

so this info must not come across to the color control?

You should be able to find PVmax in the CCGX under mppt daily history too.

The BlueSolar MPPT "PV Voltage" is available on the D Bus, so one can subscribe to these messages using the MQTT topic "N/Portal_ID/solarcharger/256/Pv/V" (where "Portal_ID" is replaced with your actual VRM Portal ID).

I can therefore plot PV Voltage from my BlueSolar MPPT 150/70 on my Home Automation system. It should therefore also be possible to add a Widget to the VRM Portal to show this data.
