5.7.2 Redundant Energy Control ( only works with one single phase
equipment)
Redundant Energy Control Feature
Only works on ECU-C in Single-phase
Cannot be combined with zero-export feature
Not compatible with split-phase (2 phases) systems as commonly
used in the Americas
Using the Redundant Energy Control function:
Select ‘Meter Settings’
Slide the ‘Meter Function’ to the ‘On’ position
Select the ‘Redundant Energy Control’ under ‘Parameter settings’
This function is to control the opening of the external AC contactor by
closing the ECU-C relay when the power of the uploaded power grid
reaches a certain power value, to supply power to external electrical
equipment e.g., water heater, pool pump, air conditioner, etc. Example:
the power requirements of a water heater is 2kW, and the turn-on
threshold can be set to 2kW, so when the array power exceeds 2KW, the
water heater is powered by the relay control and does not consume grid
power.
