DC Powermeter (e.g. for Solar, offgrid, etc.)

This article nicely describes how to use AC powermeters for solar systems. My system is operated in DC for 90% of usage though. Here, I would like to measure the power generation by the solar system.

So I am looking for a HA-compatible DC powermeter (ideally showing live Current, Voltage, Wattage and total kWH produced. Can someone point me to one of those? (<<100A, <60V, DC)

Thanks :slight_smile:

Maybe a esp paired with a compatible pzem dc energy monitor :zap:

“My system is operated in DC for 90% of usage though”
I am interested in your system, could you let me know what system works in this way?
Or do you only want to monitor some DC battery output?

Hello, I have solar panels, generating up to 10kW with a pylon tech battery at 48V. Then I have wires running through the house into many rooms, where I run what I can of DC by replacing the normal power brick by a buck converter. Only few devices, like the oven, fridge, and vacuum cleaner have to run on AC, which the get from an inverter. if there is not enough sunshine for the inverter, it draws AC from the grid directly. So it’s 90% components on DC. not 90% of power, unfortunately.
