Post subject: | Incorrect energy readings with PWM Immersion |
I recently has a solar pv installation completed including a pulse width modulated (PWM) immersion heater which activates when there is excess electricity. Now, however, when the immersion comes on the total power usage of my house is incorrect. I assume this is because my current cost (CC128) can't calculate the power consumption correctly. I have another electricity meter which does show the correct value. ie. house usage 700w + 2000w for the immersion but the current cost will show around 1500w. Any thoughts on how I can cure this or work around it somehow. |
