Monitoring solar energy with shelly and node-red

[era]

Hi, I'm working on a project that is about energy monitoring with a dashboard. So far, the project uses products from Shelly. However, I cannot find any suitable shelly product to monitor the energy input from the small solar array.

Are there any shelly or non-shelly devices that can measure the power (or voltage and current separately) from the solar array according to the following requirements?

-the device must have a DC wattmeter

or

-the device must be able to measure voltage up to 30 VDC
-the device must be able to measure current up to 2 ADC

also

-the device must be able to be integrated into node-red
-the power supply input and the measuring input of the device must be separate. This is because the voltage from the solar array can drop below the voltage necessary to keep the device running. Therefore the device cannot be supplied by the solar array.

It doesn't need to be from Shelly but it would be ideal because the whole project would be unified.

Thanks if anyone can help
