You have opened a very interesting can of worms. It does fit under this thread quite succinctly.
What does CofC stand for?
We have it as CoCT.
Those companies that certify inverter models, Co names are on the list, contact one of them for a price to get an inverter NRS certified. From a few years back, it was Euro 7000 per model.
To not mince words.
Axperts, not Infiniās, are UPSāes with an MPPT added, and have no paperwork whatsoever. I asked them.
So when people use Axpert + DB + solar panels in the same sentence, some of us have been down that route over years on another forum.
Axperts, and all the copies out there, are not NRS certified, therefore not legal to install under SANS/NRS regulations, when connected to a DB board when there are solar panels involved.
Axpert + DB with no solar panels = an awesome UPS by most standards.
Axpert + Solis grid-tied inverter = a very affordable solution.
The only Infiniās that is on the list is the InfiniSolar 10k.
The thing is, it has to be limited to the main DB circuit breaker, as per regulations.
Single-phase DBās tend to have Ā±60amp breaker = max 3.5kw inverter.
So either the inverter is limited when grid-tied to 3.5kw OR the panels are limited to a max of 3.5kw.
Another tidbit.
As people claim, insurers are wising up on solar system regulations. You cannot claim if you have circumvented the regulations. And IF there is a claim, the insurer will try and recoup their losses, if someone made a mistake, like an electrician, engineer, installer.
Note: This is not insurance advice nor am Iām an insurance broker ā¦ it is common sense.
