What is G100 Export Limitation?
G100 refers to the Engineering Recommendation ‘G100’ from the Energy Networks Association (ENA), which outlines requirements for managing export limitations from renewable energy systems like solar PV to the grid. G100 defines the parameters of Export and Import Limitation Schemes.
It is a critical regulation/protocol for businesses that generate or store energy. This is also particularly important when installing new solar PV generation, or battery energy storage systems (BESS), therefore increasing the site’s export capacity. This capacity increase, must comply with G100, otherwise risking penalties, critical grid infrastructure damage and potential site shutdowns.
Often the export limitation process must occur within a specific time frame and sometimes with stricter tolerances or additional limitations, otherwise the site may risk being disconnected from the grid by the DNO.
However, for businesses, this means they can safely contribute to the energy network without risking supply security or incurring penalties, making G100 compliance a key factor in effective energy generation and management.

Achieve Compliance with SolarEdge Custom G100 Export Limitation Solutions
G100 compliant systems require a G100 type-approved device, (often termed a ‘Customer Limitation Scheme’ or CLS). SolarEdge’s Type Tested G100 Export Limitation solution monitors and automatically adjusts energy generation assets to ensure the export limit is never surpassed.
Our Professional Services team is available from the design stage to help tailor solutions to your specific site needs or those of your end customer.
We can offer granular control of Solar PV, batteries and generators to maximise output, rather than shutting down entire systems, or sites (in contrast with many competing G100 devices, that currently do).
The ability to gradually wind-down generation to optimal levels also ensures you are maximising on available generated energy at all times, without exceeding the imposed limit.
Our G100 solution is powered by the SolarEdge ONE Controller for C&I.
Type Tested Device
Officially G100 compliant as a stand alone G100 device on the ENA type test register.

G100 Issue 2 Amendment 2 Compliant
Our solution is G100 Issue 2 Amendment 2 (G100/2) compliant, which means we meet all of the complex logging and lockout requirements necessary to comply with the most up-to-date version of G100.

Requirements for G100 Export Limitation Compliance
A mixture of on-site hardware and software is required for a G100 solar export limitation deployment. A master control panel will be installed to act as the central brain, to control secondary controllers via secure HTTPS connections, over ethernet or fibre.
As a result, the distributed central management of energy assets is enabled. In the current market, most competitors cannot offer a solution as intelligent or flexible as this.
G100 now allows for more nuanced control of assets. The SolarEdge G100 system enables logical, rule based control, keeping essential systems powered whilst also maximising self consumption.
By offering a type tested, and ENA approved solar PV export control, SolarEdge ensures an easy installation process, and guaranteed compliance with the latest regulations.
The SolarEdge Distributed Export Limitation Device
Overview: Issue 2, Amendment 2 compliant, this ENA-approved export limitation device is fully compliant with the complex lock-out requirements necessary for G100/2/2. With wireless capability and full end-to-end professional service support, this G100 device is a market leader in the UK.
Dimensions: The standard industrial panel we deploy on site is 700mm H x 500mm W. Though panels do come in some variations. For further technical details or to speak to a member of our team, please submit an enquiry.
Type Tested Export Limitation
An ENA type approved device which is one of very few available on the ENA type test register.
Wireless Capable
The SolarEdge G100 Export Limitation Device can be deployed with wireless point-to-point, meaning that distributed generation assets, spread across multiple sites and buildings can still be centrally controlled using this device – this can also help save on deployment costs.
Highly Scalable
Group a limitless number of inverters, grid meters, and isolators to suit the site, customer needs, and DNO requirements, allowing complex sites to be managed under G100 constraints from a single, simple to configure installer interface.
Low Voltage Summation
Some installers aren’t able to work with High Voltage connections. When this is a challenge we can instead connect to LV distribution points, and summate energy consumption from this.
Third Party Connectivity
Connect with a variety different vendor and model types. Seamlessly connect with with Solar PV Inverters, Battery Energy Storage Systems (BESS), Diesel Generators, Energy Meters and other distributed energy assets supported by ModBus, SunSpec, BACnet or other industry standard communications protocols.
