5.7.1 Zero Export (available on single phase and three phase, not available
on residential split/2 phase applications)
Zero Export Function
Only works on ECU-C in Single-phase and Three-phase systems
Not compatible with split-phase (2 phases) systems as commonly
used in the Americas
Using the Zero Export function:
Select ‘Meter Settings’
Slide the ‘Meter Function’ to the ‘On’ position
Select ‘Zero Export’ in the slide menu at the bottom of the page and
select OK
After turning on the Zero Export Function, please set a Power Limit
in kW. The default value is 0.
The ECU-C measures the array production and site consumption and
will curtail power production to meet (or exceed if selected) the site
consumption. Example: if the Power Limit is set to 0 and the site is using
10kW and the array is producing 8kW the inverters will operate at 100%.
Conversely, if the Power Limit is set to 0 and the site is using 3kW and
the array can produce 8kW the inverters will curtail power production
to meet the demand. In addition, the ECU-C is designed to dynamically
adjust to the changing demand of the site automatically in real-time to
realize the full potential of the array.
