Power control (with HEMS)

The power control overview displays the values for active power, reactive power, and measured values at the grid connection point (= point of common coupling). A blue'Log XC is required to carry out power control functions.

Power control: basic approach

If you want to operate your blue'Log for power control purposes, the following is one possible setup workflow. If you do not carry out the steps in this order, power control may not function properly. 

1. Configure plant data for PV, battery, or both. See Plant data (with HEMS)

2. Plan your master-slave setup. See Controller operation (with HEMS)

3. Configure active power and reactive power (if applicable). See Active power (with HEMS) and Reactive power (with HEMS)

4. Activate power control. See Active power (with HEMS) and Reactive power (with HEMS)

5. Check one of the following to confirm that power control is working properly:

   1. Power Control > overview page

   2. Cockpit > Charts. Select the relevant values and view them in the chart.
