Small-Scale Embedded Generation requirements in South Africa are administered by municipalities, so the forms, thresholds and technical conditions are not identical between distributors. The practical work is the same everywhere: describe the installation accurately, show how it connects and is metered, and support every equipment claim with a document that names the exact model.
1. The requirement belongs to the municipality, not the supplier
The SSEG resource portal is managed by Sustainable Energy Africa and hosts municipal guidance covering regulations, processes, tariffs and application procedures, with documents contributed through the AMEU-SALGA resource pack. That portal is a reference library. It is not a national single-window application, and it does not replace the distributor's own process.
Start by identifying who supplies the site and what that municipality currently requires. Ask for the current application form, the current technical conditions and any capacity threshold that triggers additional assessment. Requirements are revised over time, so a checklist downloaded a year ago should not be treated as current.
2. The core document set to prepare
Names and formats differ between municipalities, but the material reviewed during an application consistently covers the following areas. Treat this as a preparation list, then confirm the authoritative version with your municipality.
- Application and registration details: property, account holder, installation address and the intended operating mode.
- Single-line diagram: generation, storage, changeover, protection and the point of supply shown in one drawing, including where the metering sits.
- Equipment schedule with model-level documents: exact manufacturer and model for each inverter or storage unit, with the datasheet or certificate that names that model.
- Metering information: the proposed metering arrangement and any change to the existing meter.
- Installer details: who is responsible for the installation and for commissioning.
- Operating intent: whether the system will export, and under what conditions.
3. Why the diagram and the grid assessment attract the most questions
The electrical diagram is the fastest way to show whether the installation sits inside the municipal conditions. The SSEG portal publishes single-line diagram examples and metering guides precisely because installers repeatedly get these details wrong or omit them. A diagram that shows generation and load but not the changeover, protection or metering boundary usually comes back with questions.
Where an installation exceeds the municipality's threshold, a grid-impact study may be requested. The scope, the applicable technical standard and the threshold are municipal decisions. If your design depends on a specific answer, get it in writing from the distributor before ordering equipment, because a study outcome can change which equipment configuration is acceptable.
4. What the equipment supplier can and cannot provide
A supplier can supply the technical inputs: the datasheet naming the exact model, interface and protection information, and the operating limits of the unit. That material supports the application. It does not complete it.
A supplier cannot register the installation, sign the single-line diagram, or decide whether a municipality accepts a particular model. Be sceptical of any blanket statement that a product "is approved" for a market. Approval is specific to a model, a configuration and a distributor, and it is evidenced by a document you can read and check. If a claim cannot be matched to a document naming the model in front of you, treat it as unconfirmed.
5. Plan the sequence backwards from commissioning
Work backwards: approval is normally needed before the installation is energised and before a bi-directional meter is installed or reconfigured. That means the document pack has to be ready well before the installation date, and any equipment substitution during the project needs to be re-checked against the submitted documents rather than swapped quietly.
Keep one folder containing the submitted application, the drawings that were approved, the equipment documents actually installed, and the commissioning record. If an inspector asks which inverter was approved and which one is on site, that folder answers the question without reconstructing the project.

Frequently asked questions
Is there one national SSEG application for South Africa?
The SSEG resource portal managed by Sustainable Energy Africa hosts municipal guidance, processes, tariffs and application material. Because the requirement sits with the municipality, the forms, thresholds and technical conditions can differ between distributors. Confirm the current requirement with the municipality that supplies the site before you submit.
Can the equipment supplier complete the SSEG application?
No. The supplier can provide model-level technical documents, datasheets and interface information that the application refers to, but the application, the single-line diagram and the registration are the responsibility of the installer, the owner and the municipality.
Why is a single-line diagram requested?
It shows the municipality how the generation, storage, changeover and metering are arranged, and where the point of supply and protection sit. The SSEG portal publishes single-line diagram examples and metering guides as reference material; the specific content required remains a municipal decision.
Does SH Energy hold NRS or utility approval for its models?
Do not assume so. Any statement about standards compliance, listed equipment or approval must be confirmed at exact model level with documents for the specific unit. Ask for the certificate or test report that names the model, and confirm its acceptability with the municipality.
Discuss a documentation or sourcing enquiry
Send the exact model, your proposed configuration and the documents you already hold to jimmy@sunhongenergy.com, or contact Jimmy on WhatsApp. For related preparation work, see the battery and inverter compatibility checklist, the RFQ checklist and our quality and documents page. Acceptance decisions rest with the municipality and the distributor, not with SH Energy.
