Posted March 31, 20231 yr Hope i can get some help . I'm in the process to apply for permission to install panels and inverter . i have spoke to the guys and the axpert inverter is seen like an ups system . I need to send a line diagram of what i plan to do . Is there someone that can assist me with that or what the basic requirements is for the installation. Its basic eskom feed inverter then inverter to small sub DB that will supply my lights and basic stuff . Thanks
March 31, 20231 yr Stellenbosch does not fall under CityOfCape Town, lucky, otherwise the Axpert would not have been allowed Edited March 31, 20231 yr by HendrikBigChief

The Axpert is actually allowed . Its not on the list because its an off grid inverter and cant feed back into the grid .
March 31, 20231 yr Where are you going to get the signature of a professional engineer to sign off the design?

Hendrik its not grid tie . no feeding back into the grid . you basically need your COC for the installation , the line diagram and the completed form. Off-grid / standby systems: Electrical installation Certificate of Compliance A Commissioning Approval Letter will then be issued within 10 working days Application for the connection of Embedded Generation - Copy.pdf
March 31, 20231 yr The line drawing guide/objects/components/glossary is on the City of Cape Town website https://resource.capetown.gov.za/documentcentre/Documents/Procedures, guidelines and regulations/Embedded generation schematic drawings SK5276.pdf Depending on your layout the line drawing is done using those components Not sure if there is a Microsoft visio plug-in you can import with these objects I know Victron has a visio plugin that might work, but I did not cross-reference the objects

Is a Deye/Sunsynk system that is configured to not push back to the grid also seen as "Standby Hybrid SSEG"?

However it is drawn as if you can export back to utility. With a CT as we know this will be blocked.
April 4, 20231 yr I've also got an Axpert Inverter, living in CT, wanting to add some solar panels. COCT sent me 2 documents, the one Dieter linked to and the document attached here. They added this comment, "For a standby system the installation can be signed off by a qualified electrician and the installation must conform to SANS(specific to the application)" There was so much confusion around all these "off grid" inverters, which is nothing more than a glorified UPS. Check the diagram and note where it says the inverters don't have to be on the approved list. Standby and Off Grid installations.pdf Edited April 4, 20231 yr by BTTB
