Hi everyone, yesterday I strapped the new SolarSense 750 to my pannel array with an endclamp (Maybe add this to the assembly instructions?) and have a question: [SolarSense750] How do the sensor calculate the active aerea [m²] of the panel because the sensor measures W/m²? In my case the module…

Hi @Sebastian , the SolarSense doesn’t actually need to know the area of your PV panels. A 420Wp panel will produce 420W at an irradiance of 1000W/m² (STC). Consequently, the SolarSense can estimate the instantaneous output of the PV array by dividing the Wp rating of your installation by 1000W/m² a…

Now another question came to my mind: The device is also made to check a new spot for solarpanels. Is there a way to import the recorded data via the VictronConnect app? So no GX device is needed at that new location

Hi @Sebastian , currently that is not possible. Only when connected to the SolarSense via VictronConnect you can see the historical data. I will add this as a feature request, but can make no promises if and when this will be implemented.

Hi Luc, Can we please have VRM adjusted so it shows Watts in the dashboard view versus just irradiance? Basically like how it shows in Victron Connect would be ideal. [Screenshot_20260623_024150_VRM] Victron Connect: [Screenshot_20260623_024222]

Hi @Brucey this change is already on the backlog, but hasn’t yet been picked up.

Hi @Sebastian , this feature has been implemented starting VictronConnect V6.40beta8. [image]

Will any manual be available for study? Currently, there is none available under ‘Downloads and Support’.

Hi @CZvacko since the SolarSense is quite a simple device, the datasheet and manual are combined in one document. The datasheet download includes all instructions for usage and installation.

If there is no manual, is there a description of the available MQTT values and their meanings? I just bought it and have a few questions.: In MQTT, I noticed the topic ‘N/xxx/meteo/20/TxPowerLevel’. This means, how strong is the received Bluetooth signal from the perspective of the Cerbo GX devi…

Hi @CZvacko , the topics you mention aren’t relevant for normal operation and might change without notice. That being said: TxPowerLevel indicates the output power of the SolarSense radio in dBm (at low battery this is reduced). It does not indicate signal strength at the GX device. UnspecifiedRemn…

Thanks for the information. Is there another way to find out how the GX device measures Bluetooth signal quality?
