Thank you Adiel. Those were my thoughts; however, the "Kodak Hybrid 4.6" looks much more like the Solis than the Voltronic tribe.

Button pressed! Deye 5kW hybrid possibly on its way. Interestingly, there would seem to be zero technical difference between the Deye 5kW and Sunsynk 5kW (also the Inge 5kW). According to the specifications, the Sunsynk 5.5kW "Super Parity Inverter" may have some differences but, other than some software differences evident on the LCD panel, I can identify no hardware differences.
My choice was definitely influenced by the above discussion. Thank you all. I'll report back on installation and operation.

I have installed the Deye 8kw a week ago. Took me a while to figure it all out, but it works like a charm. True Hybrid. Mixes energy from either PV & Grid, or PV & Batteries. But the real nice thing is the level to which you can customise it. I set mine to "load first". As soon as the sun comes up, it starts powering the house, and use the excess to power the batteries. When the sun sets, it starts running of batteries. It set it up to go back to grid at 40% (20% to protect the bateries and 20% buffer to cater for load-shedding). Around 22:00 my batteries run out, and it reverts to grid. So I have no electricity bill between 08:00 and 22:00 - even run my geyser of it. And when the sun is shining, it charges my batteries again. With the touch of a button you can change it to load the batteries from grid if need be. Really impressed with it. Busy ordering more batteries as we speak - to take me totally off grid on sunny days... 

Thank you to Adielk, Steve and Manilow. If you search the web for Kodak / Solis (the hybrid models) and Deye / Sunsynk (and all of their clones, there are plenty!) I seem to find that there is a ton of technical info about the D/S products. Kodak (certainly not identical to the Solis) seems to be sold only in SA and Zimbabwe and I cannot find any user feedback for the hybrid models.  Youtube is pretty useful here.
The clincher really is as Adielk, Steve and Manilow say, the Deye Sunsynk offers much more for your money.
The question that ManiLow raises, panel rated power, is interesting. I did a calculation based on incident solar radiation which suggests that the amount of energy you can actually harvest (on average) is limited more by area covered than by panel power. My capital cost (panels plus mounting structure) per Watt harvested  was lowest at about 190W/m2 (about 330W per panel). Of course, this calculation is made a nonsense by the considerations:-
1. You can really only use averages - the daily radiation could be considerably higher and you would lose that energy.
2. My figures are for coastal Western Cape. Inland and East will be completely different...
3. I used sizing and efficiencies for an average panel (from JA Solar and Canadian Solar) and there are many whose performances will be different.
4. I have lots of roof and intend adding panels in time (a point in favour of the Deye/Sunsynk)
I intend to revisit this calculation to see if I can develop a relationship between panel power rating and incident radiation, accounting for some of the factors affecting efficiency of conversion. Your thought would be very welcome.
Oh, and I'm informed (unofficially) that our municipality - who make a nice profit from electricity sales - are sticky about any inverter rated more than 5kW...

Good evening everyone,
My finger is hovering over the button to buy my home solar system and I'd really appreciate some informed opinions. The basics consist of 12 x 340W JA panels and 2 x 2.4 kWh Pylons, with a hybrid inverter - and I've narrowed the choice to either the Deye (Sunsynk) 5kW or the Kodak 4.6kW Hybrid.
The Kodak would seem to be a South African product, appearing nowhere else in the world... That's not comforting. I believe that it is a rebadged Solis; should that calm my nerves?
What about their relative reliability? Supplier / manufacturer support? If anyone has experience to share I'd be very grateful.
Whilst I'm here, any thoughts on installation costs? It is a fairly simple install, panels on a single pitched corrugated roof with clear access to the main db and plenty of space for the inverter and batteries within 3m.
Your thoughts, ladies and gentlemen, would be valued.
