Victron can be considered the Mercedes of domestic inverters, but like a real Mercedes, there are pros and cons.  Here are a few things you should know:

1. Victron uses different modules to make a system.  So you need more "stuff".  More wires, connectors, etc.  This also needs more time to install.  Other systems normally are single-box solutions.  Your installation could look more like a mad scientist experiment than with other inverters.  😆

2. Victron inverters are referred to as low frequency inverters.  They use 50Hz toroidal output transformers (usually 2 of them) to do the low-to-high voltage step-up.  Most other inverters are "transformerless" designs.  Toroidal transformers are big and HEAVY.  They are also rather expensive, especially if we talk of a few KW.  They give a totally galvanically isolated output which has advantages over the normal inverters that have some DC HV bus connected to the AC output.  Now, toroidal transformers are very efficient but they DO have losses.  I expect about 3%.  This loss needs to be added to the H-bridge switching losses that all inverters, including Victron, use.  So I think that a Victron might have slightly less efficiency.  Oddly enough, the no power idle current on Victron inverters is normally better than other designs.  Victron also has sleep/ power saving modes which other inverters don't have, but I am pretty sure that no Powerforum member would be interested in these modes anyway.

3. Victron make a lot of IP65 rated products.  This has historic reasons due to their origin in the boating/yachting sector.  This means they are 100% water proof.  It also means they are throw-away products.  They cannot be repaired.  The electronics are cast in resin or rubber compound.  The Multipus itself can be opened and repaired.  The MPPT on your list, as far as I know, is potted in rubber.  So the MPPT is not serviceable.  (Go to Youtube and search for Victron MPPT repair and you find a lot of angry people with hacksaws and angle grinders trying to literally only replace a blown fuse.)

4. Victron only keeps spares for 10 years.  Now, I don't have too much of a problem with that per-se, if they would repair down to component level.  I know someone with an old inverter which is considered unrepairable because they cannot source the three PCBs used on that device.  THIS I consider a very, very poor show.  Sometimes, when things go wrong, PCB tracks can get burned and that would require a completely new PCB for a reliable repair.  But mostly, individual components can be replaced.  Either they can't or won't do that - so it seems.  I refer to a specific case I know of in Cape Town.  Perhaps they have some brighter techies up north.  Who knows.

5. Victron normally has no, or very minimalistic user I/O control panels/displays and relies on doing everything via Bluetooth or WiFi.  People like it.  I personally don't.  I think we already have too many devices in our homes that radiate EMF.  But hey, I am a nut case when it comes to that.  So you can scratch out this point.

So if you have the money, go buy yourself some blue bricks. 😀

Those are tried and trusted components so you should be fine.

Good day Rinelda and welcome.
I use a Victron Multiplus II and it is amazing. P1000's reply above is taking a jab at Victron because they are generally more expensive than similar product offerings from other companies but the warranty, support, online community, software, firmware updates etc. still tips the balance in their favour in my opinion. 
Please give us details of your installation for us to make a more informed recommendation regarding the MPII.
 

Hi All. I made this video.
Pierre, I take exception to your insinuation that I am punting Victron. Let me state for the record that I am in no way affiliated with Victron and I hardly know the local Victron guys. I only met one and I don't like him. I simply use it and I believe it is an excellent product.
The point is not if the King can find out what the state of charge is by asking the BMS, it is what it can do with the information, and the answer is nothing.
You need to watch the video a few times more, because you missed the point completely. Let's be clear, the Axpert cannot blend power linear between PV and Grid. It does not convert the grid to DC, convert the PV to a suitable DC level, add the two and invert the sum of the DC power to AC. That is expensive circuitry, and that is why the Axpert is so cheap, it simply switches via a relay. The point of the grid tied inverter is to blend the grid and PV power before it is fed to the Axpert. The disadvantage is that the PV switches off under islanding conditions.
Note that Voltronics, do not claim the Axpert to be a Hybrid Inverter. It's Hybrid inverters are the Infini series. They blend the power from the PV and grid.
If you don't get the difference in the Victron and Axpert functionality offered, its sad. There are so much that the Victron offers the user if you understand it. And yes, King will catch up but by that time Victron has gone much further ahead.
