You can get a Luxpower SNA with a 5.12kw Dyness/Volta/Shoto/Hina Ess and all accessories required for the install at around R39k-R40k. Then add cost of labour/coc.
 
Mirua technology has a Luxpower SNA 5kw + battery backup system incl installation at R42,450. Not bashing any other supplier/installer nor am I trying to advertise them, just giving a heads up that pricing has come down significantly and you can get a 5kw backup system installed with good components for cheaper than R54k.

Thanks for the comment. Please advise with what you do not agree?
Understood, E/L will be installed as recommended.
I am a handy individual  whom has not got problem with compensating for someone's knowledge. I have a problem paying or a fly by night who'd like to charge for something simple like mounting an inverter and battery.

I completed the build today and am very pleased with how it came out. I now need to figure out all of the correct settings for the battery and inverter. One annoying thing is the inverter fans come on every few seconds.
Herewith some images of the completed build:

@Terence0424, the diagram is exactly how I wired my system, except for the SPD. I asked on the original thread but did not get a reply. As far as I have read, the SPD also required a ground connection. From the socket I took the ground straight to the earth bar, and from the earth bar to the SPD ground connection. The rest is wired as per the diagram.
In terms of fuse and CB sizing:
For a mobile trolley solution connected to a wall socket, the recommended AC In CB was 16A because that is what the wall socket rating is. 125A DC fuses or breakers as that is what my inverter manual recommends. 25A RCB is a recommendation received on this forum. SPD @ 20KA should be fine.
I am really not sure about the CB on the output side. Currently mine is still wired with the 25A earth leakage, but as mentioned another guy recommended a 2P 10A CB for overload. I have not received any more responses when asking about it.

Hi @Terence0424, I bought the DC disconnectors and fuses at Lite Glo in Randburg, Gauteng: https://www.liteglo.co.za/
Just a note - on another forum someone suggested that I add a 2P circuit breaker of around 10A on the output side. He reckons that the earth leakage on its own does not provide overload protection. I am not sure if I need to remove the earth leakage and replace it with the said circuit breaker, or just add it before/after earth leakage. I asked but he has not responded. None the less, my system has been running for a while now without any issues. I only run small loads on it though.
As for the grounding, I am not sure. Hopefully someone on here with the required knowledge will answer you.

If your generator is connected via a 3 position transfer switch the socket you are using should have power if you don't have a transfer switch you could connect straight to the generator

New poster but been reading up a lot on this forum for insight into solar.
One thing I can say is that solar is extremely complex. Initially I thought I would give it a DIY go because I am a very handy person and do a lot of things around the house myself through self education, trial, error and eventually success. However, solar has proven to be on another level for me and a very expensive "experiment" for a DIY enthusiast, so I would rather leave it to the experts.
A little bit of background: Single, small simplex unit of 88sqm, work from home full time, very low electricity usage (My bill is usually around R350 - R400 pm). What I basically need is a system to power all of my essentials which would include:
Full time
One PC or a TV/Sound system (not run simultaneously) A ceiling fan Fridge Router + ONT for internet Charge a phone or something similar Occasionally:
At night it will be 2x 10w LED flood lights On the odd occasion switch on an airfryer/microwave/washing machine/dishwasher/kettle for a limited time Non-essentials like the geyser/oven/stove will not be connected to the inverter/solar system.
After a lot of research I have decided to go with a 5kw solar system (Initially I looked at a 3kw system, but many guys who I spoke to advised against it saying the components are sub par etc - better spending more and going 5kw). I received two quotes at around the R88,000 mark which will include the following:
5kw Deye/Sunsynk inverter 5kw Shoto/Dyness battery (Dependent on what stock is available) 5x455w Longi/JA/Canadian solar panels (Dependent on what stock is available) All accessories, installation and COC included It might be slightly overkill for what I want to use it for, but the area where I live has had 2 days of electricity in the last week. With stage 6, COJ are unable to keep up with the amount of calls, break downs, cable theft etc, so we sit for around 2 days without electricity, and one day with electricity. So the cycle continues on and on.
My questions:
Will the 5x455w panels be sufficient to power the system for non-essentials throughout winter/summer if we experience prolonged periods of breakdowns from COJ/Eskom? My roof is ideal and has sunlight most of the day on sunny days. I can get the same system with a Luxpower SNA5000 for R11,000 cheaper. I feel that it is worth it going for Sunsynk/Deye based on what I have read, but I would like to know if it is not overkill for what I am looking for and potentially worth it to save the R11,000? Thanks in advance for the advice!
