Zero Export Device
What is Zero Export Device (also called solar export limiter) ?
In several parts of India, NET metering is not available for small medium capacity or big capacity of On-Grid Solar Power Plant. And it leads to a huge loss of power production due to unavailability of net metering.
A solution to these problems is Zero Export device (also called Zero Export Controller or Solar Export Limiter) [and our product name is ZED Advance], which enable solar system owners & operators to limit the amount of solar power that their systems export to the GRID. With Zero Export device you can run your PV plant without net metering.
The integrated power analyzer of Zero Export device / Zero Export Controller / Solar Export Limiter measures the total power at the point of coupling 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.
Zero Export Device is also known as Export limiter or Zero Export Controller or Solar Zero Export Device.
Zero Export means there is no export of power from solar power plant to grid. Zero Export device eliminate any surplus power generation from solar power plant, hence there will be no export of power to grid.
Zero Export Solar Inverter:
Zero Export solar inverter is the solar inverters which have inbuilt Zero Export device. But most of the solar inverters don’t have zero export facilities. With ZED advance any On-grid solar inverters can be converted into Zero export solar inverter.
Application of Zero Export Device:
Zero Export Device (or controller) has following application
1. Solar without Net metering (click here to learn more).
2. Off-Grid without Battery back up (click here to learn more).
3. DG synchronization with solar power plant (click here to learn more).
Zero Export Device (also called Solar Export Limiter) Price:
Price of Zero Export device varies from 8,000 Rs (IND) to 1,50,000 Rs (IND) in India and abroad, as per the plant size. Zero Export device [ZED Advance] prices are same for different makes of solar inverter.
Price of luminous zero export devices will be same as of SMA Zero Export Device or for any other make of solar inverter.

Zero Export device (also called Zero Export Controller or Solar Export Limiter) required Current transformer along with 10 core, 1.5 Sqmm Cable at the incomer from 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 (also known as solar export limiter or Zero Export) 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).
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
Frequently asked questions
Is ZED Advance compatible with GROWATT make inverter
Yes, our ZED Advance is compatible with every model and size of SUNGROW make PV inverters
Do I need two ZED Advance for Zero Export and DG Sync with PV plant
No, ZED Advance can work both as Zero Export and DG Syn controller. One controller can eliminate any surplus power generation during Grid power available and can save DG Set from back feeding during power cuts
Do I need two ZED Advance for two different makes of inverters on a same PV plant?
No, one ZED Advance can control multiple make of inverters on a same PV plant.
Can ZED Advance monitor DG SET or GIRD, whenPV plant is shutdown (due to weather or for maintance)
Yes it can monitor both DG SET and GIRD, even if the PV plant is completley shutdonw.
Can we connect ZED Advance on HT panel side?
Yes, we can install ZED Advance on HT Side too
Can ZED Advance communicate with weather sensors?
Yes, ZED Advacen can conmmunicate wtih weather sensors too.
Do I need clearance from local grid authorities for the installation PV Plant with Zero Export Device?
No, You dont need any clearance from any authorities for the installation PV Plant with Zero Export Device.
I can run a 1MW of PV plant with 100kVA of DG Set?
Yes, you can. With our zero export device you can install any size of PV plant with minium size of DG set requried at site.
