Wow, these are some awesome prizes!

Thank you very much, this helps a lot. I now just need to find brackets and isolators for the panels👍👍

Hi, Ok, so according to the specs, it can do 3000W, which means I can do 3 strings of 545W panels at 120V? I'm referring to the Canadian Solar 545W panels. https://powerforum-store.co.za/collections/featured-products/products/545w-super-high-power-mono-perc-hiku-with-mc4-evo2 Johan

Good day, I am planning on replacing my current Trojan Lead acid batteries with a Sunsynk Battery Max 208AH 10.65KwH battery. I understand that there are some setting changes that is needed for it to work properly. Firstly, has anyone made use of this battery and inverter combination at all? My second question is around the MPPT controller. I am currently using 4 *300w solar panels, and I think I may have some issue with the panels as I rarely see anything more than 70v and about 750W being generated from them. On the sticker of the inverter it states that the maximum DC input voltage is 120V. I am looking to add more solar panels to my roof. Do I put these in parallel to make sure I do not exceed the maximum voltage and then ramp up the amps, or how do I determine what the maximum number of panels is I can connect to this inverter? Attached is a photo of the specs. Thanks in advance. Johan

Just what I need to replace my ailing lead acid batteries

Looks like I can use this as my new battery

Thank you very much for this response. I have done a lot of electronic work a few years ago and may just as well try and fix it myself, failure to do so, replace it, as I would in any case have to do that. I am in Cape Town, and it seems that there aren't anyone around here that can assist with repairs.

The battery voltage is currently at 51.3v, and when the flickering happens, the voltage stays the same. I took a video but it's too big to load here. I have 8 T105 6v Trojan batteries. They are about 7 years old, but I have taken good care of them. They are nearly due for replacement in any case.

Here is the model number

Hi everyone, I have the above inverter, and it started misbehaving a few weeks ago with what seems to be "tripping" of sorts where the three led's beneath the display flickers all at once and I can hear some relays clicking on the inside of the box. This happens when it needs to convert DC to AC. I managed to get it to work again some time ago after the first time it happened by only switching on the solar panels and the batteries, no AC into the box, and it managed to recover itself after a while. After it recovered, I was able to switch on the "AC In", and it worked fine again, until tonight, when it went crazy after Eskom power went down, needless to say, it's not generating any output, and I had to switch it off completely. Is there anyone that has knowledge of these inverters that can look at it and try and so some troubleshooting, perhaps repair if possible? Any input will be greatly appreciated. Johan

Good day, I have a 5KVA Axpert that started flashing on and off this afternoon, producing no power any longer. Are there any reputable repair companies in Cape Town that can look at it? Johan

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

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

Thanks. How did you declare this, as this is exactly what my setup is, 4 solar panels charging my batteries in conjunction with the grid.

So what you're saying is that if I uncouple my solar, then I can let them know I no longer have a SSEG?

Thanks for your replies. I have one more query though. What is your understanding of "change-over" switch. Should there be another device between the inverter and the db, or is the inverter seen as the change-over?

Another thing I've been thinking about is what about people who have similar installations, but do not have solar panels, but charge their SSEG's from the utility, and use it during power outages. Surely they would also have to register their systems? How would those systems be identified? Perhaps I'm asking questions to the wrong forum, but asking these to COCT yields absolutely no answers.

I still think that R6.5k is a lot for a diagram. My incoming connection is about 5 metres from my db, and my installation is 2 metres from my db. I cannot see how that cost can be justified.

Morning guys, Late last year, I received a personalised mail from COCT regarding my SSEG installation. They did aerial surveys, and because I have solar panels on my roof, they derived that I have a SSEG installed. I now have to register my SSEG with the council, their reasoning is that they need to know who has these installed, as there is a potential that these may shock their technicians if the power is swithed off and not properly installed. Problem I have now is that it looks like it requires the following: A schematic diagram showing details of the off-grid SSEG installation in relation to the wiring of the premises and the City’s electricity grid. A Certificate of Compliance (CoC) and test report is required only if an off-grid installation is integrated and interlocked with a change-over switch between the utility electricity grid and the customer electrical installation, as follows: a. Passive standby UPS utilised as off-grid hybrid SSEG as defined in the City’s Requirements for SSEG document, and; b. SSEG alternative supply in terms of SANS 10142-1: 2017 My system utilises an Axpert inverter, so I guess that their request is valid, problem being that the "schematic diagram" they require, seems to be only obtainable by an engineer as far as my investigations go, and such an engineer comes at a costly sum of R35k. Has anyone else had similar requests from COCT, and how did you comply with this request? Thanks Johan
