I know, the handbook states the accuracy of the EM is 1%. Whatever that means.
Given the maximum current is 50A or 120A, the maximum wattage is 220V x 50A = 11.0kW, or x 120A = 26.4kW.
But what does this mean for small wattages?
Do I always have an absolute precision of 11kW x 1% = 110W, for the 50A solution?
What about measuring small values like 10-50W? How precise is the Shelly EM then?
Did somebody compare Shelly EM with Shelly 1 or 1PM, for such small values?
Thank you!
