Zero Export Controller

Net Metering not approved? Or taking a lot of time?

TrackSo’s Zero Export Controller ensures no extra power is sent back to the grid. Instead, all the solar energy produced is used to power local needs. The controller monitors and adjusts the inverter’s generation based on the load requirements.

Without it, you might end up paying Lakhs in penalty. 

  Benefits:

●   No back-feed to the grid.

● Monitoring & Controlling via same device.

● Real-time control of multiple inverters at a time.

● Universal Solution for all Inverter Brands.

●  Avoid huge loss of power production and Lakhs due to delays in net metering.

Zero Export works on a simple logic as mentioned below:

Step 1 – Read Active Power from the net meter.

Step 2 – Is Active power > Max Set point? If yes, increase power on inverters.

Step 3 – Is Active power < Min Set point? If yes, decrease power on inverters 4. Repeat from step 

NOTE:

Minimum set point: It is the minimum required power input from the grid supply

Maximum set point: It is the maximum required power input from the grid supply in case there is enough solar power being produced to cater the load.

Following is a simple SLD to showcase how Zero Export works in a solar PV system. To be able to do the zero export, we need a zero export meter [bi-directional meter] on the incoming side. This meter should be MODBUS RTU enabled so that our Power Control device can communicate with it to read the ACTIVE POWER values.
