Just listening to people it seems a lot of installers are recommending them. One would assume they talk out of experience.

Following @PsyWulf
good post I have also seen original brands accepting a fee to just add a seller/manufacturers name on their product. One would then assume it is the same quality and this fee is just for marketing. 
Not on inverters but on batteries. 

I think the heart of the Luxpower SNA is also Axpert based. 2 x MPPTs is an attraction as well as the lower starting voltage. Well priced I would say. 

I belief that the fact that Phocos launched the Axpert like Any grid inverter that also sells at a 50% premium at an European show that it is not a clone. The MPPTs have different voltages etc. The frame does look the same as the Voltronic inverters. Just my own take on this brand. It also has a very good reliability score. 

The use of "Clone" is sometimes used incorrectly
The truest meaning of Clone in the Inverter context is an "unofficial" Copy,reverse engineered often and with sometimes dubious parts
The second use sometimes is instead of Rebrand aka Licensed where the manufacturer buys the technology and relabels it for their use
Clone is also sometimes used interchangably with "Axpert-like"
 
There's a big thread on how to try determine if you have a Copy-clone or a Rebrand-clone,including checking the Serial numbers and Parts
 
This being said I believe the RCT and Mecer units are Licensed units that can even be paralleled between Brands (so identical hardware and software)

Copied from point 2 of the article:
"The KODAK Home Inverter has been updated to a new version, a tried and tested Voltronic system it’s one among the hottest and affordable inverters on the market.
It is basically an Voltronic clone and does have the same features as the VMIII above."
I am not trying to discredit any brand merely doing some research to avoid any issues. The writer potentially used a poor selection of words?
I however thank you for your valuable input and reccomendation. 
Sad that the BMS is limited. I have had a look on the Hubble website and they also stipulate there, that it's not compatible and voltage based charging will need to be used. I was considering the cloud link, but there are many that aren't happy with it, but it seems to only be with the AM-5 batteries.
I did not even consider fan noise or PWM so it's a very interesting feature to watch out for. PWM fan control seems like quite a no brainer and can't see it adding crazy costs to implement. All inverters should have this! 
Thank you for afirming the Kodak and it's support. I will look into the VMIV and the OG 5.6 and concur with you that the extra 600w will be welcomed. I will check for pricing and compare everything.

How does that point 2 in the article state its a clone? 
The Kodak VMIII (OG) is not a clone. Its a  rebranded Voltronics Axpert by SegenSolar, and they support their products locally very well I need to add. 
The VMIII (now superseded by VMIV) is a value line product based on the Axpert  MKS. Amongst other, they have no PWM fan control, and becomes more noisy than the ones with control. Also it only support Pylon as far as BMS support is concerned. 
I would rather dish out the extra bucks for the MKS IV  (Kodak OG5. 6) , and you also have extra 600W of throughput. 

The only true Voltronic Axperts that I know for sure are RCT, Kodak & Mecer.

I presume the following to be clones, but maybe there are some that may be genuine.  Would be good if others could point those out.

Hi, thanks for this diagram. Is this neutral bonding needed at all? What happens if this is not done. I am also bbusy with a 8kw Sunsynk with one Hubble AM-2 for office backup oly. Planning to add panels and more batteries later. Thanks for your insight.
 

Hi Jelly, the concern here is that you will discharge beyond the specs of the battery & that will cause the Battery BMS to protect that 1 battery & the system will trip. Hence when one specifies a system you try your best to match the system as 1:1 at the very least. The Voltronics MAX system for example has a Maximum discharge limit setting for the battery bank. This limit will not be exceeded. I cannot talk on behalf of Equipment that I do not install, maybe a more knowledgeable person with a Sunsynk or Hubble can comment but this is the basis of where the.concern comes from. 
Again for a Sunsynk seasoned installer. My humble Voltronics has this neutral to Protective Earth bond done automatically within the machine. The Sunsynk/ Deye needs this item added externally. 
On face value this seems correct however, make sure you cover not just the 8kW of inverting capacity but also the pass through current that the Sunsynk can provide. The Sunsynk can conduct more than the 8kW because of this passthrough current. Observe that value if you can find it. Remember the Breaker is there to protect the wires, not the appliance. The wiring size must also be able to accept your breaker size. I have a feeling that the passthrough is carried out through a seperate port & might need its own breaker. A seasoned owner or installer might clear this one up for us. 
 
200A is ok for 50mm DC wire. There is a great guide in the downloads section called wiring unlimited by Victron. Great place to sniff. You can use smaller cable between the 2 batteries but your main + & - must be at least 50mm wire. This is where the maximum of the discharge of the 8kW inverting capacity will be delivered through. So example, if your Hubble is 5kWh each to make up 10kWh in parallel. That is 100ah X 2. So that means between these 2 batteries 100ah is delivered from them each. So the cables between the 2 can be up to 25mm (worthy of 100A). But the inverter will draw 184a through this bank of 200ah & it will use these wires to do that. So they need to be thicker. 
 
The placing of the CT coil is very important with the Sunsynk, it's grid tied architecture makes it very sensitive to where that CT is positioned. An experienced installer will guide you on this one. The CT is also quite small, it will fit into most places & again an experienced operator will get this right. 

Talk to @Leshen

With Lithium you can buy one now then add another later without affecting the system balance - this is a key benefit over the other battery types. And the answer to your question is yes it shouldn't be an issue
