Good day,
I have a -48V solution for a telecom application. The radio base has grid connection and the solar system supplies in day time, and also supplies as self consumption.
There is a ET340 connected to Cerbo GX to measure grid consumption as both sources PV and Grid supplies the load.
My question is about the accuracy of measurements from the ET340 versus the solar charger as DC and AC source and mainly the accuracy of the ET340 versus the meter from the Grid as I want to compare the measurement from the electricity bill. At the end I want to assure my customer the measurements are reliable.
Thank you in advance for your help.
