Zero Export Controller/ Device
Prevent back feeding into the grid
SuryaLog Zero Export Controller/ Device
The SuryaLog Zero Export Controller for solar power plants, developed by SuryaLogix, is designed to prevent excess solar power from being exported to the utility grid, functioning as a reliable zero export device for solar installations. It continuously monitors solar generation, grid consumption, and site load parameters, then regulates solar output according to the facility’s power requirements.
The controller works with the solar inverter to manage generation based on real-time operating conditions. By calculating the total load requirement and comparing it with available solar generation and grid consumption, this zero export device helps ensure that solar power is used by local loads while minimizing unwanted back feeding into the grid.
This solution is useful for commercial, industrial, and institutional facilities where grid export is restricted, net-metering approval is pending, or site demand changes throughout the day. As a dependable zero export controller, it can regulate solar generation during low-load periods, including breaks, holidays, weekends, and other operating conditions when electricity consumption decreases. This allows the solar plant to continue operating in a controlled manner while aligning generation with the facility’s actual demand.

Frequently Asked Questions (FAQs) About Zero Export Controller
A Zero Export Controller (ZEC) prevents excess solar power from flowing into the utility grid. It automatically adjusts inverter output according to real-time site load.
It measures real-time import/export power using a meter or CTs. It then regulates inverter output to maintain zero export to the grid.
It may be required when the commercial rooftop plant operates with the grid but surplus export is not permitted. The requirement depends on plant configuration and DISCOM regulations.
A CT (Current Transformer) measures electrical current at the grid or load connection point. This data helps the controller detect and prevent reverse power flow.
It communicates with compatible inverters through supported communication protocols. It sends power-limit commands according to real-time site load and grid flow.
Both terms are commonly used for solutions that prevent solar power export to the grid. The controller refers to control functionality, while the device generally refers to the associated hardware.
Zero export is suitable for self-consumption where grid export is restricted. Gross metering exports solar generation to the grid under the applicable tariff mechanism.
The price depends on plant capacity, inverter compatibility, metering, communication, and integration requirements. Contact SuryaLogix for a project-specific solution and quotation.
