Power Control: Zero Export

Avoid loss of power production due to delay in net metering

On sites with no Net Metering, the Power output of inverters is throttled to optimize total energy generation for captive consumption and enforce zero export of energy to the grid.

Get Zero Export Solar Controller at the best price in India from Logics PowerAMR.

Key Benefits

Smart Control: The device provides real time power control and will ensure that the inverter ramps down the solar production, in case of low/ no load.
Flawless Protection: Our System ensures that the inverter doesn’t trip and minimum or no reverse feed-in is sent back to the grid.
Graphical representation: Client can log on to the PowerAMR website and see working of power control on real time through the single line diagram and graphical illustration.
Remote Monitoring: PowerAMR ZED simultaneously acts a Data Logger and provide real time and historical data monitoring on our Solar Management Platform
Deemed Generation: The system estimates the amount of energy throttled due to impact of zero export device at every 10 minute interval.

System Brief

In case of unavailability of net metering, to use solar as per load requirement, we need to sync solar with the grid. In this solution, solar will take only reference voltage from the grid, but does not export power to the grid. This way the user would be able to use grid-connected solar plant without export.

Working Principle

In case of Zero export, bidirectional meter shall be installed at incomer side,working with a maximum and minimum set point which can be configuredthrough software. The zero export solutionpolls connected energy meters and inverters to determine the current load and help user to use solar as per demanded load. This solution will throttle the power of solar inverters as per building load and there will be no Export to grid.

Load from grid shall be ensured to run at 4% to 8% of the sanctioned load, it might change depending upon the load variation/ fluctuation.

The working principle is as follows-

1. Read Active Power frommeter

2. Is Active power > Max Set point? If yes, increase power oninverters

3. Is Active power < Min Set point? If yes, decrease power oninverters

4. Repeat from step1

Note-
Minimum set point: it is the minimum power input from the grid
Maximum set point: it is the maximum required power input from the grid in case there is enough solar power being produced to cater the load.
