Good morning fellow form members.

 

Does anyone have a list of inverters that conform to the above standards?

 

I have an RCT Axpert 5K, and have to tell COCT whether it conforms to the standard?????

 

Thanks

Johan

That's the local version of IEC62040, which is compliance tests for UPSes.

As far as I know the Axpert inverters only have the "CE" mark, which is self-certification and some have jokingly said it's an abbreviation for "China Export". They have no other official certifications.

Follow up: What is interesting is that if you google for IEC 62040 and Voltronic, it seems they do make some UPSes with that certification, and they also have the testing facilities to test for it. But unless, something changed, the last I remember of this is when former forum member TTT emailed them to ask and they admitted that "CE" is all they have.

Ok, so this then mean that my UPS will not make the cut for certification by the COCT?

I know there are people who have them signed off. I don't know how they did it... I've never known, nobody has ever given a definitive answer... if the letter of the law was followed these inverters would not be installed for anything other than off-grid setups.

But, as also pointed out frequently, in Australia it is perfectly legal, approved and everything. But that might be because someone (Giant Power I believe) did the legwork.

Has anyone come across the answer, by any chance? Do we have a body that does this certification, here in South Africa? 

I sit with the same problem - not knowing anything, Cape Generators installed three of these inverters for us, (3-phase) and we cannot go off-grit due to irrigation pumps. Now I sit with them - seems like Cape Generators is a Fly-by-Night company. They did give me a COC certificate but the inverters are not on the municipality's list, so what should I do? Take them out and resell them? At a huge loss?

OK so I can answer this. The CoCT inverter list that's approved are inverters tested under NRS 097

NRS 097-2-1:2017 Ed 2.1 See Annex 3 of EG Requirements under reference documents at http://www.capetown.gov.za/elecserviceforms. 

As per that Annex 3 - Huawei Power-M is a passive/active - standby UPS designed topology and is constructed as per the explanation of SANS 62040-3 Annex 3

CoCT exclude all SSEG as it is not tested under NRS 097. It is impossible to test a SANS 62040-3 UPS under the same criteria as a NRS - grid tied inverter.

 

So I bought the Huawei power M. Fantastic by the way. And it's approved based on the architecture and way it's installed. It does not fall into the grid tied inverters list. The people at CoCT that have drafted this haven't done their homework completely and are missing a large chunk of knowledge. 

 

Hence if you do it right under the SANS the approver will pass it. You caj contact Huawei direct for information. Or Johan at begreenenergy in cape Town.

Hi

I have the same question as Johan, but I have a 5 Kw KODAK Inverter. Will it pass under SANS 62040-3?

Thanks
