A Small-Scale Embedded Generator, commonly referred to as an 'SSEG', is a term used by municipalities and Eskom to describe a system that is connected to the Electrical Grid and has the capacity to feed electricity back into that grid. In this context, an SSEG specifically refers to a solar system equipped with photovoltaic panels. It is important to note that this definition does not include backup inverter-battery systems that lack solar panels; only grid-connected solar systems qualify as SSEGs.
Understanding which grid your solar system is connected to is crucial, as there are generally three possible providers: Eskom, a Municipality, or a third-party provider such as an Estate. The entity from which you receive your electrical account is typically the operator of the grid to which you are connected. This is also the entity to which you are accountable for obtaining SSEG approval for your system.
Off-grid systems, by definition, are not connected to any external grid and therefore are not subject to SSEG regulations. The SSEG requirements apply only to systems that are grid-connected, regardless of whether they currently feed power back into the grid. The mere potential for feedback means these systems must adhere to the rules set by the grid operator. Unless a system has acquired SSEG approval, we generally configure our systems to ‘Zero feedback’. However, the ‘Grid Set-point’ will cause a very small and usually negligible amount of power to be fed back to the grid.
Eskom is in the process of developing and implementing rules for SSEGs connected to its grid. It is important for system owners to stay informed about any updates, news releases, or communications regarding changes to these regulations.
Homeowners’ Associations (HOAs) within Estates typically have their own specific rules governing the connection of SSEGs to their grids. Some Estates allow power feedback, while others may have unique power wheeling agreements in place. It is essential for system owners to familiarise themselves with the SSEG rules of their particular Estate, as these will directly impact the operation of their solar systems, and the credit that solar system owners may be eligible for.
Bitou Municipality has established a clear and efficient SSEG approval process, now available through an online application platform. While it is preferable to apply for SSEG approval prior to installation, the process does accommodate systems that have already been installed. Applicants can register an account by visiting the designated website at https://apply.sseg.org.za/ and clicking on ‘Register’ under the ‘Applicant Login’ header. Completing all fields marked with a red asterisk is required to submit the application for approval. There is also an instructional video available here.
Some details needed for the application must be provided by the solar installer. These can be requested directly via email at daryl@ecosunergy.com. Additional supporting documents are also available under the Documents tab on this website.
All systems installed by ecoSunergy adhere to SANS 10142-1-2 specifications and utilise inverters certified to NRS 097-2-1 standards, ensuring compliance. So besides the administrative and perhaps bureaucratic processes, acquiring SSEG approval should be a formality.
Off-grid systems, as the name suggests, are not connected to any external grid and thus do not require SSEG approval. Nonetheless, these systems are installed in accordance with the same electrical standards and specifications as grid-connected setups. A Certificate of Compliance is always provided to ensure safety and to meet insurance requirements.
For some users, particularly where monthly connection and availability fees are high compared to actual usage (often the case with Eskom connected systems), it may be worthwhile to assess the long-term financial benefits of disconnecting from the grid and operating independently. ecoSunergy has always encouraged Energy-independenc and we will be happy to discuss transitional steps for those considering this option.
