A Zero Export Controller is an advanced power management device designed to ensure that no excess solar energy is exported to the utility grid. It continuously monitors the power flow between the solar inverter, site load, and grid connection, making sure that all generated solar energy is utilized within the premises. This makes it an ideal solution for locations without net-metering approval, allowing users to maximize solar usage while staying fully compliant with grid regulations. The controller automatically modulates inverter output in real time, perfectly balancing solar generation with on-site demand. By preventing reverse power flow, it protects electrical equipment and ensures smooth, stable system performance. In simple terms, it enables a grid-tied solar system to operate efficiently and safely under strict zero-export conditions.

The Zero Export Controller is an ideal solution for sites where net metering is unavailable or export restrictions apply. It enables complete self-consumption of solar energy while ensuring grid safety, operational stability, and regulatory compliance.
Manages high-capacity solar systems efficiently and prevents any reverse power flow to the grid.
Optimizes on-site energy usage and lowers electricity costs without exporting surplus energy.
Supports uninterrupted operations with smart load management and stable solar utilization.
Helps businesses achieve energy independence and safeguards equipment from voltage or grid fluctuations.
Setting up the PowerAMR Zero Export Controller is quick and seamless. The system integrates with inverters and the building’s grid connection to manage solar energy safely and efficiently. Follow the step-by-step guide below:
Mount the bidirectional meter at the incomer to measure real-time active power between the solar plant and the grid.
Set maximum and minimum power limits as per the site load. The controller automatically adjusts inverter output to match demand.
Connect the controller to compatible inverters using RS485 or MODBUS for real-time communication and synchronization.
Enable online monitoring to access live status, alerts, and historical system data through the Solar Management Portal.
With this setup, your solar plant runs intelligently—ensuring maximum self-consumption, safe grid operation, and uninterrupted energy supply.
The Zero Export System enables grid-connected solar plants to operate efficiently even without net metering. The inverter takes only reference voltage from the grid while ensuring no reverse power export, allowing users to consume solar energy based on actual load requirements without violating regulatory guidelines.
A bidirectional meter continuously monitors load conditions. Based on configurable minimum and maximum set points, the controller adjusts inverter output in real time to match on-site energy consumption. Typically, 4–8% of the sanctioned load is drawn from the grid to maintain operational stability.
Tracks active power through the bidirectional meter to determine exact load requirements.
Increases or decreases inverter output based on load changes to maintain smooth operation.
Ensures that no excess solar power flows back into the grid under any conditions.
Constantly monitors and regulates inverter output to maintain perfect solar-load synchronization.
