Zero Export Controller for Solar Power Plants | Poweramr

Zero Export Device for Solar: Controller/Meter

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.

Key Benefits of Zero Export

Smart Control: The Solar Zero Export 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 controller, bidirectional meter shall be installed at incomer side,working with a maximum and minimum set point which can be configuredthrough software. The zero export solution polls 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.

What is a Zero Export Controller?

A Zero Export Controller is a smart power management device that’s exactly designed to prevent excess solar energy from being exported to the utility grid. This device continuously monitors the power flow between the solar invert, load, along with grid connection, and ensures that all generated energy is used for self-consumption.

This makes it great for all those locations without net metering approvals, and helps users maximize solar utilization without even violating grid regulations. The Zero Export Controller automatically adjusts the inverter’s output in real-time, and maintains perfect synchronization between solar generation and on-site demand. By avoiding reverse power flow, this device not only safeguards electrical equipment but also ensures that system performance is stable.

Simply put, it’s the key to running a grid-tied solar system efficiently, even in zero-export conditions.
