Thanks for all the feedback everyone After chatting to various signage and solar places, all parties agreed that it's important to indicate the 'dual sources' on the DB and inverters - but no one was able to understand or point to a regulation outlining any need for signage on the exterior of my property. Engineer was happy to concede - considering no clear regulation is in place in the COCT requirements. Appreciate all the help.

Hello, I'm in the process of completing all my commissioning requirements after doing a residential solar installation in Cape Town. The engineer states that I need to have some sort of signage on the outside of my property that states 'alternate electricity supply on site'. He says that this is a requirement - to which I said I've literally never seen it on anyone else's property. Does anyone have an example of this? I really don't want to be openly advertising that I have solar on my house - given the rise in panel theft.

Just the one battery - so that makes sense then (correlating closer to 30A). I'm trying to brush up on my knowledge of amps = watts / volts - and the picture is starting to get clearer if I take the 57.4v charge voltage * 30A = 1700W. I'll chat the the panel installer (who also did my inverter) and get him just to double check it all. Really appreciate the help, thank you

Definitely noticed an increase my side too. When we moved onto a Prepaid meter over a year ago, I started tracking my daily unit usage - and it was around 7-8 units for the house per day. The DAY we had our inverter and battery installed, it's gone up by the same +-2.5 units a day. I've set my inverter to only charge the battery at midnight for a few hours, but it's for sure that extra power needed to charge the system. Looking forward to the reduction when panels are in

Sorry to piggy-back off this, but reading it RE battery charge rates has me nervous that my shoto batteries are charging too quick. I have the same Shoto batteries as OP. When the charging happens at midnight (No panels yet, so charged via Grid), I can see the batteries charging at like 1600W, but not sure what is the right setting to adjust on my LuxPower Inverter to make it charge slower. Is it the 'Charge Current Limit', or 'AC Charge Battery Current'...?

Sorry to hear Torino. I've definitely isolated the problem down to the changeover from when Eskom drops, and the Inverter and battery takes over. My garage door's F1A250V fuse blows EVERY time. Right now, my only solution is to keep the garage door motor switched off, and I just switch it on manually when I need to open and close the garage door. Getting panels soon - and then hoping that it doesn't happen anymore - since reliance on grid should be no more... so no more changeover. That's the idea... fingers crossed.

Hi there, I currently have an inverter and battery setup, and looking to add solar panels soon - but I believe this requires the SSEG forms to be completed. I've had a look at some of the SSEG application diagrams online, and I just don't understand them. Tried to take a crack at one just to make sense of it all, but my question is... How technical does this diagram need to be? Would my diagram be suitable to attach as part of my application? Most solar installers want to charge 6k plus for the SSEG application, but I understand that the process itself is free... it's just their time obviously in putting the diagram together (so I'm trying to avoid that). Thanks in advance for reading and for any help given.

Thanks for all the feedback everyone Checking voltages between Neutral and Earth isn't something I know how to do, but let me go do some reading and see if I can monitor it. Much appreciated!

In late December, we had a battery (Shoto 5.12khw) and inverter (Luxpower SNA5000) installed to help with load-shedding - and the first day after it being active, I noticed that the changeover from Battery > Eskom resulted in our 2.5A alarm fuse being blown AND our 1A garage door motor fuse blowing. Since then, my alarm fuse has been fine, but my garage door fuse has needed replacing 5 times. Whilst fuses aren't expensive, it is still a pain in the ass to keep replacing fuses. For additional info, we do not have a voltage / surge arrestor installed as part of our setup - but I'm wondering if that will solve the issue or if it's something else entirely. We didn't have ANY fuse blowing issues prior to the system being installed.

Hi there, I'm looking at having a 5kv LuxPower inverter installed - and from the two contractors I've spoken to, I need to have the backup power's DB board installed my garage near the inverter, due to space issues near my actual DB board (not enough). They plan to have our lights and plugs running on the inverter, leaving the stove and geyser off. From my understanding, they need to run a flat twin-earth cable from the inverter through my roof to the main db board, then run another flat twin-earth cable back from the DB board to the one in the garage (bringing those lights and plugs back), so that the inverter will be the 'master' of those items. On the one quote, I see it's been quoted as 4mm wire needed. I want to go up into my ceiling and run a neat 6mm flat twin-earth in my own time (not connected), so that one end is out by the garage, and the other end is available by the DB board for them to use... my roof space is really small, and I enjoy being up there (weird, I know). I just don't know how many I need to run. On the DB board, it's 3 'switches'... one for lights, two for plugs. Is that enough to go onto one cable? Plus the other one for the inverter? So two x 6mm cables... should I run three just because? Or is two enough? Do they need to be inserted into any kind of tubing? Sorry if this is confusing. TLDR; I want to save my contractor some time (and try avoid them going into my ceiling because it's super cramped), and laying the flat earth cables myself (not connecting them).
