No regrets whatsoever. 
Turned out the developer put 16 tubes on a 200L geyser  
So i installed 150L geyser(3kw element) and connected it to the 16 tubes + 20 tubes for the 200L(2kw element)and connected them in series. Also added 2 X Geyserwise Max to control the pumps and they own batteries. It works like a charm. Water gets to 65 and 55 daily on average and i even have enough hot water to shower in the morning and all this without even using electricity. On good days i even get to 70 degrees.
I have thought of getting a gas water heater for the rainy days but its not a priority at the moment. 

Looks like allot of thought went into this. 
Depending on your budget, i would target the reduction of your dependency on eskom first. As much as getting a battery and an invert would cater for load shedding, your consumption is still slightly high. 
Consider getting few panels, 6 - 8 when installing the inverter and the battery. That way you killing two birds with one stone( catering for load shedding and reducing the monthly cost). Also look into a smaller element for your geyser, belive me, it makes such a huge difference. I just changed mine from 4KW to 2 KW, now my solar production is enough to cater for geyzer and house consumption. 6KWH production maxing at 4KWH. 
Look into Hubble and Sunsynk, currently using sunsynk and loving it, unfortunately i cant comment on the Hubble but allot of guys have mostly good things to say about it. That should set you back R50K for inverter and battery, then panels 6 x 455W canadian solar should be around R15K then installation and accessories. 
I built my system over phases, within four months and i feel i wasted money by going the gell batteries and growatt inverter.

I have a 200 liter hp 20 x evacuated tube self siphoning geyser it is at 15 degrees West from North at about 45 degree angle. On Sunday we did not use water the whole day and it went up to 76 degrees when I got home late the afternoon, today it sits at 65 degrees after the maid has been using water, the worst I’ve seen it was 44 degrees after a very cloudy day. One important thing with evacuated tube geysers are to make sure to apply the heat sink paste to the copper tubes otherwise it will loose lot of heat due to bad contact. I installed my own geyser and made sure and applied the paste thick.

Is this to replace the municipal meter, or is it going to set between the property (or part thereof) and the municipal meter? If the former then work with the municipality. They will know that a meter with a certain serial number is installed at stand (whatever your stand number is). If they find any other meter they will presume that monkey business is going on.
 

Just my 2c, growatts are terrible when it comes to blending power. I changed my growatt to a sunsync and have never looked back. 

5kw sunsync @ R25k odd,
5.5 Hubble battery + @ R25k odd
Poly panels - 455w 14+ @ R20k odd
 
Including installation i think you looking at R80k odd

I agree with a combination approach, also agreed that simplest is best. So a fire pit with a donkie, fed with the branches of the tree that was cut down because it shaded the panels.

Can i suggest you go with 2 x 5KW Sunsynk inverters. Instead of 2 mppt, you'll get 4. They come in handy if you have a complicated roof like mine. 

Well, just to add some more info: Do I really need such a system? The answer is NO, but it's a real FUN to play with it!
BTW, "Youda" means "redneck".

Have you noticed that coffee made from alternative power always tastes sweeter somehow?
