How do modern digital power meters respond to 'burst fire' or PWM controlled loads , ie Immersun etc,
feeding export power to immersion heaters?
Taking for example a 3kW load, and 2kW export surplus. With the 'burst fire' system, switching blocks of full wave power, the meter would register an import of 1kW when the load was switched on. This means that to save 2kW of export you have to pay for 1kW. of import. Have I got that right?
How does this work for PWM control? - how does a digital meter respond to the PWM waveform?
thanks,
John.
