Hi all
Been searching the site regarding MUST inverters ... any feedback on these? specifically the 3000w version
Thanks
 
Check out the City of Cape Town's list of approved inverters that you have to use for a registered solar installation. Then ask yourself why any random brand of inverter that nobody has ever heard of is not on that list.

Some know brands not on it, most axpert based inverters are not on there. I dont find that list of any use, you can just "pay" someone to approve your solar install.
 
you mean pay someone at the CoCT offices, good luck with that, I am an installer in Cape Town and know a lot of the guys and have founf them to be quite a decent bunch and I dont think anyone of them will approve a un-approved inverter installation, spend a bit more and do it right.

Why do installers charge R5500+ to do the "registration" when it is supposed to be free? And why do you think only CoCT has this requirement? It is additional red tape to prevent solar uptake. How much do you pay CoCT to be 1 of their "registered installers"?

Geez, this topic has been beaten to death already. The application itself is free, but do you expect the installer to spend the time and effort preparing the application and the documentation and then submitting it, and then walking it through council for free? The R5k or whatever is not the application fee, it's for the installers time and effort to prepare the application and then successfully get it through council.

So then this is in fact a mountain of admin and red tape. I will obviously not be able to all this by myself. This has been beaten to death but people told me it is very simple and free to register. Clearly they were just lying. I have looked at the form. Parts of it must be filled in by the installer. Clearly unneeded red tape and admin.

Now please answer the other questions:

1. Why do you think only CPT has this mountain of admin needed to register a system? All other munies have no registration at all.

2. How much do you pay CoCT to be a "registered" installer?

Well, you can put your tinfoil hat on and say that they want to keep a registry of all solar installations to prepare for some sort of future tax or levy on solar installations, or you can take your tinfoil hat off and accept their explanation which is that it's for safety reasons so that people are forced to have their solar installations installed by qualified professionals, and so that they know where potential points of backfeeding into the grid are to prevent their workers from getting electrocuted when working on transmission lines.

So CoCT has a mountain of admin and red tape to "register" a system for "safety" reasons but no other muni in SA including other DA munies have this requirement.

CoCT is already taxing solar with inflated solar tariffs as well as off-grid by banning off-grid.

Please now for the 3rd time, answer this question:

How much do you pay CoCT to be 1 of their registered installers?

Inverters need a NRS certification in order to be "approved" for connection to the grid.

Considering that manufacturers of Axpert type inverters merely just copy or clone other designs it makes sense that they would not submit their inverters for certification. If they cannot be bothered to design their own product why will the be bothered to ensure it meets certain standards.

Hybrid type inverters need to be able to block grid feedback, a lot of " Axpert" marketed hybrid inverters cannot perform this basic function.

Not a big conspiracy. It's all on the website:

It is red tape. That is true. But it is the cities grid. I'd feel the same about connecting up to the sewerage system or the road network. You have to meet planning standards and have things approved so that the system works for everyone.

If you want the wild west and broken grids, go to Joburg. I'd rather people connecting generators to the grid are checked over by someone competent so they don't feed back and electrocute me or mix up a phase and blow up my equipment.

Grid tied systems need to do a lot of work -- have plans approved etc. and have a ECSA registered person signing off.

But standby/off-grid systems only need a CoC.
Neither of the above need to use a CoCT registered installer.

In fact there is no list any more on the main going solar or registering an installation page. That was a separate scheme in the early years of encouraging a nascent industry - a list to help people get started and not use cowboys. No requirement to use their listed installers, just the listed inverters.

Well said, and I may I just add that by doing things by the book you not only keep your insurance company happy but also your neighbours and anyone else who might be affected by some cowboy installer installing a dodgy system that burns your house down and takes a few of your neighbours with them.
 
So in conclusion. MUST not on the list.

Really shouldn't be trying to use an axpert clone for PV generation and certainly not grid feedback.

But back on topic. Any Axpert like is pretty good for power backup. Mecer, Mr Power, 5Star... Largely all the same aren't they?

Not from CT, so whatever was said above your post, pfft. I just wanted feedback on the MUST units :) LOL
