Zero Export device enable solar system owners & operators to limit the amount of solar power that their systems export to the electricity grid or DG SET. Export limitation means that the amount of solar energy in the system is controlled by adjusting the set point of the inverter in the system
The integrated power analyzer measures the total power at the point of coupling and compares this with the adjustable set point of the controller. When the consumption from the grid or DG SET 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.
In some part of India it takes several moths to get NET metering done for their On-Grid Solar Power Plant. It will leads to a huge loss of power production due to delay in net metering. With Zero Export device you can run your PV plant without net metering.
The integrated power analyzer 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.
So many of you live in an area with an abundance of solar while your electric power is very expensive and unreliable. Some utilities will not allow you to sell your excess production back, or will just pay you pennies for feeding your precious solar energy back to the grid.
The use of solar energy for self-consumption has many advantages: reducing a site''s carbon footprint, the decrease in energy costs, or the possibility of reselling this energy to the national grid when local regulations allow it. Solar panels are directly connected to the grid through inverters; the energy produced is transmitted to the site for self-consumption or is returned to the grid. However, in some countries, local regulations mandate power limitation and zero export, preventing any energy injection into the grid.
The injection limitation consists of controlling the amount of electricity produced by a photovoltaic installation injected into the grid. Limiting active power injection may be necessary to relieve the grid and reduce the reinforcement costs that this would imply.
To guarantee the network’s stability, the network manager may require limitations on injection into the network. This provision avoids excess injection, especially on weekends and public holidays in industrial buildings where the electricity demand is lower.
In some countries, the injection of electricity is prohibited: it is called zero export. In compliance with the law and to ensure the supply of a reliable electricity network to the end customer, some countries prohibit injection limitations. It avoids pollution of the network through the generation of “undesirable” harmonics. This interdiction helps to maintain a good quality network.
Take Morocco’s case; the opening of the electricity network to low voltage relative to self-generation relies on the principal supplier’s (ONEE) ability to find solutions to compensate for losses related to it. It presents a real shortfall for the latter and the twelve other distributors present in the country such as Lydec, Redal. Law 13-19 prohibits the self-producer from feeding back the energy produced to the grid, imposing conditions on PV systems, such as implementing a Zero Feed-in system when connected to the grid.
Controlling the electrical production of a site by taking into account climatic variations and consumption while ensuring that the current is not injected into the network proves to be a real challenge. Fortunately, there are solutions to facilitate the energy management of your site.
Before installing PV, you can ensure that your installation''s size best matches the consumption of the building, aiming to optimize your rate of self-consumption without the need to manage power limitation and zero export.
Some controllers are energy management systems that allow you to manage your energy consumption efficiently and reliably. Zero export controllers allow you to manage your energy consumption efficiently and reliably. Elum Energy’s ePowerControl ZE has a wide range of compatibility with commercially available inverters.
