Zero Export Device

Payperwatt is one of the major manufacturers of Zero Export Device, we provide Zero export solutions for rooftop as well as utility-scale solar power plants. Our device is compatible with most of the grid-tie solar inverters. We provide both supplies as well as the installation and commissioning of Zero Export Device in all major cities.


Our team has experience of more than 5 years in installing and commissioning more than 200 Plus Zero Export Devices around the world. Our Plug and play 5 in 1 zero export device, make it easy for solar EPC companies to install the device on their own. If they require any assistance, we are always available in their service.

5 in 1 Zero Export Device:

ZED Advance is the most powerful Zero export device, it has 5 in-built features and it is compatible with more than 17 Plus makes of solar inverters. 


ZED Advance has the following 5 features:

1. Zero Export Device: To restrict the export of power

2. Export Limiter: To limit the amount of power exportation. 

3. Generator PV Controller: To save generator from reverse power of the solar plant.

4. Weather Monitor: Monitoring the weather with weather monitoring sensors. 

5. Data Logger/Remote Monitoring: Monitoring of solar, generator and grid.

What is a Zero Export?

Zero Export means there is no export of power from the solar power plant to the grid. Solar power plants export power to gird, in case of excess power generation. To stop this export of power, solar inverters need to be controlled via an external controller called ZERO EXPORT DEVICE.

What is a Zero Export Device?

Zero Export Device limits the power generation of the solar power plant as per the load demand. So that no excess of power can be generated. Which pervert the reverse flow of power from the solar power plant to the reference power source [Grid & generator]. 

Our advanced design has inbuilt remote monitoring of solar power plants as well as gird and generator. With Zero Export solar plant owners can go solar without net-metering [smart meter] and they can use their grid-tied solar power plant even during a power outage.  With Zero Export Device generator owners can run their generators in synchronization with their grid-ties solar power plant.


What is a Zero Export Solar Inverter?

Zero Export solar inverters are special-purpose solar inverters that have inbuilt Zero Export devices. However, most solar inverters don’t have zero export facilities. To convert any solar inverter into a Zero Export Solar Inverter, an external controller is required.

 Zero Export Device Price:

The price of the Zero Export device varies from 60,000 Rs (INR) to 1,50,000  Rs (INR)  in India and abroad, as per the plant size. Zero Export device [ZED Advance] prices are the same for different makes of solar inverters. 


That’s means, the price of Luminous zero export devices will be the same as of SMA Zero Export Device or for any other make of solar inverter.​

Zero Export device required Current transformer along with 10 core, 1.5 Sqmm Cable at the incomer from the grid for the load the measurement as shown in illustration.  And compares this with the adjustable set point of the controller. When the consumption from GRID is above this set point, the solar energy will be increased, when the consumption is below this set point, the solar energy will be reduced. ZED advance also required LAN cable (cat 6) to communicate with Inverters as well as web portal (for online monitoring).

How does a Zero Export Device work?

During commissioning of ZED Advance as Zero Export Device, we set the sharing point at 0%  (or 5 to 10% in care of frequently high load variations). 

Lets take a case when the load is vary and ZED Advance control the output power of Solar (on-grid) Inverter as per the load.


In below case PV plant can produce 100kW of power and the load varies, but ZED control the output power of the Inverter so that there is no surplus power hence the plant can run without net-metering. And you can see how the load is shared between PV plant and Grid

In below case output power of PV plant varies and you can see how the load is shared between PV plant & Gird.
