Dawie's Solar Setup

That's a decent price in the current market, congrats. Just note that the registration with CoCT can cost you R 5k plus as it has to be inspected and signed off by a registered professional (ie, an engineer or registered "technician"). Does you installer have someone that he uses for this that he works with?

All kinds of problems can possibly arise if you later get an independent oke out and he identifies all kinds of shortcomings. Will the installer then rectify these issues without any additional costs to you?

I had no idea that there might be additional costs associated with the registration with CoCT. The installer is providing an electrical engineer to perform the COC and generate an installation report for the PV install, including a wiring diagram.
 
Updates on my install or lack of it.

- Installer got stuck on their previous job and could not start mine on Friday.
- Agreed to do the install today but now it is raining in Cape Town.
- Install postponed until middle of next week.

Luckily, I still have two EcoFlow units that can be used for LS until that time.
 
Install completed today. Ended up being 12 x 460 watt panels. Six facing north as in the photo and six facing east. I will add another photo of the east facing panels as soon as can get on that side of the roof.

Nice, I'm still mulling in whether to pull the trigger on panels. Would be wiser to wait a few weeks for our company to announce the annual results, to see if we are in for a bonus or not. Missing out on these super long Summer sun hours is hard to swallow though.
 
Here is a view of the east facing panels. As luck would have it, today is overcast.

Been looking at other member posts on inverter settings and settled on the below for now. Might still remove the Grid ticket from the 09:00 to 13:00 slot.

Nice system. Will install similar soon. What is your solar yield like?
 
OK, so you want to discharge to 25%, and shutdown at 20%.

5% safety margin for loadshedding is 256Wh, are you sure? Your base load must be tiny.

I run mine down to 30%, also shutdown at 20%, but my 10% safety margin is 1050Wh, which I need to take me through load shedding.
 
That makes more sense. My base load is not that tiny. Let me rather make some adjustments.
 
Also, there is a video on the Sunsynk website on the Equalization V and how it is only used for AGM batteries. Go check that out

You can leave your shutdown as is, but then add what is required for LS to your system mode schedule.

With a 5 kWh battery, it's 50W for every 1%. So assuming a baseload of 500W, you'd need 10% per hour during load shedding. Or 40% for a 4 hour slot.

So this means that none of the slots on your schedule should go below 60% (20% shutdown + 40% for LS). Or you could do something like 15% shutdown, which means that none of the slots should go below 55%.

It's very tricky with one battery, an extra one would have given you more flexibility...
