Sitting with this same prob. Did you find a solution?

Correct, my bad.

I never recommend to work on electricity if you're not a qualified electrician, it's also against the law, and against your insurance 😉 Having strings of 3 in series should be fine, paralleled up to 6 strings to stay below the max Isc. No your inverter should trip, or could burn, never pass the max ratings. On reputable brands they just clip in over power (wattage) conditions, but I'm not sure how Axpert would react.

You can confirm this with your supplier or installer.

The data sheet states max Voc to be 145V and Isc to be 60A. So in short, don't exceed 145V or 60A then you'll be fine.

I think those Goodwe inverters with another casing stuck on, I won't be surprised if Goodwe is a rebrand of Alpha or the other way around, did you see their Storion range? It's got a physical Goodwe in that gets installed into the Storion cabinet, they don't even try to hide the Goodwe by sticking another brand name on. And all the batteries across the ranges have similar connection boxes and terminals than the Goodwe inverter.

@The Terrible Triplett You've read it right 🙂 The OHS act regulations states that the User or Lesser of an electrical installation (If there's a lessor, it depends on what the contract says), whichever the case may be, is responsible for the safety, safe use, and maintenance of the property.

😮 The escalation 😆

I'm an electrician licensed to do COC's and in our industry this is a common problem, 20-30% of my coc's are for installations that was certified but didn't comply. The biggest problem is that coc's isn't regulated, the ECB did this when the Chief inspector gave them the rights to regulate all of SA's coc's, then a few years back, think 2009, that right was taken away from the ECB because the government said they'll regulate it themselves, how many installations do you think has been spot checked since then? Nada. Or even kept record of? Nada. The only record keeping that happens is the coc number being registered to the electricians' name, which gets sold in bulk. But none of the registered numbers could be linked to a certain property if the original old yellow paper has been destroyed in an accident or even deliberately destroyed by a person. The law states that a COC is valid for an eternity if nothing has changed on the electrical installation. OR in the case of the property being registered/transferred (sold), the COC may not be older than 2 years. Also note that insurance companies loves COC faults as it's one of the 2 points they hammer on when a property burns down. They demand a COC, and the fire departments findings report to check for arson. If the COC states you've got 25 plugs, but they are able to count 28 plugs, you can kiss your insurance payout goodbye (or most of it) as you've issued them a false legal document, they never tell you this when you sign up for the insurance though. My recommended solutions for future coc's: Stay away from these cheap R500-R850 COC's. I know everyone is always googling and calling for the cheapest coc prices around, but it's most (not all, you might have an 20m2 building) of the time the guys that doesn't conform and just makes a quick hit and run, usually not available in a year or two when you're getting problems from the new owner who notices there's live earth wires on a light when changing the fittings. Remember a coc is valid for an eternity, you got the electrician so you stay liable. It's like selling an i7 working computer, the customer returns blaming you that you sold him a i7 when infact its an i5, you cant then tell him it's your electricians fault because he told you its an i7, you're going to have to take the punch and do whatever the law states around selling goods, and if that electrician is gone, well then you've got one less foot to stand on. There's such laws regarding property laws as well, I'll get to that. Only use ECB registered electricians. found here You can take up any disputes with them, they'll sort out the electrician, even if you're not a member. This also ensures you that he's got all necessary qualifications and all licenses are up to date (Make sure to check his ECB registration card, credit card size, and that it hasn't expired once he arrives on site). They also push us to do refreshment courses every now and again to keep the standards up to date. They can also assist in court if you get taken to court because of your old property that didn't comply to standards (in case the new owner takes you to court), they assist in shifting the blame to whoever is really responsible. If you used an registered electrician this can usually help to sort matters outside of court. Stuff can get viscous in this industry, very little are actually aware of this. Keep in mind that a COC is a legal document, if the property doesn't conform to what is written on that document then it is an illegal document (because lies are written on a legal document, like in this case earth wires being live, but was stated that it's not). ECB still continued regulating COC's (the electronic versions at least) for their registered electricians, so always make sure before using an electrician that they are very well issuing the electronic version registered with the ECB, this will allow you to always have an electronic version available that's stored on their servers, and to make sure there's evidence of that specific coc number being registered to that property and that the specific electrician did it, which should also keep track of his latest contact numbers and registration numbers. Google the companies name. In most cases where I've done coc's for non-compliant properties, just a simple google search revealed bad reviews/comments. Clients then always says they didn't think about this and again, was only looking for the cheapest. A bad comment here and there is normal, you can sell a perfect apple to someone, there will always be that one or two clients that will complain because the apple isn't the correct color shading. But if the comments are about the electrician not answering calls, or going missing, or stealing, etc. then red flags should go up. Reputable companies doesn't change numbers and doesn't dodge calls, but rather resolves issues. Solution regarding your original post: Don't change anything on the installation, if something has changed and you didn't get an updated COC, the original COC will be voided. Personally I always take pictures of all aspects of the installation to cover myself in this regard. If this electrician did the same and something has changed, and he's got the photos to prove it, then there's nothing you can do and everyone will just be upset because of the time wasted. Contact the previous owner to contact the electrician that did the COC. Tell him you're giving him the opportunity (If you want to, I would be generous in this regard) to go back to the premises to make sure his COC complies to standards and that you're getting a second opinion once he's states the property does comply (even if he fixed something after he's been back). Then get your second opinion (another electrician that doesn't know about what is going on, otherwise it wouldn't be an honest opinion). If he doesn't fix something, you can contact the ECB, if he's registered they can advice on what the next steps should be. If he's not registered (the ECB might also advice on the newest procedures to follow here) you can contact the Department of Labour(DOL), they will start a dispute and advice you to get an Approved Inspection Authority (AIA). He will then go out and check the whole installation and report back to the DOL. If the AIA finds the property doesn't comply but the COC states it does, they could take away his license. I think they also contact him at some stage to fix his stuff before they take his license, but he'll then have a tick against him for future disputes if he does go to fix it, but atleast not loose his license. You can sew him (electrician) without using the above procedures, but your attorney will then charge you to do it himself anyway. Maybe with the added advantage of holding the old owner responsible for the legal fees as he used the (in the wrong) electrician. I've rarely heard of people going to such extremes. but according to law that's what the procedure is like, usually the electricians gets such a fright when stuff starts happening against them they just give in and go fix it. But every time people leave problems like this, those electricians just goes out and scam's the next person. And the next. And the next. And usually it's innocent people who loose properties or gets harmed by an unsafe installation, that fall victim due to an electrician that just wanted to make a quick buck.

How is it holding up so far? What is the model number or seller? I've purchased two a few months ago from a reputable electrical wholesaler, they now only last about 4 hours, where they lasted about 2-3 days (+- 8 hours per day) when new. The battery is a sealed pack of 3x lithiums of which I cant find any info on, as it doesn't have markings. The worked great when they actually lasted the whole day at least.

No, I dont know the Huawei at all, or any of it's values, but the Pylontech BMS will complain about something.
