Some help for the new kid

Sustainable are saying the Growatt and Axpert MKS is a Hybrid and they definitely are not. I have an Axpert and it's 100% an Off-Grid inverter.
 
As much as you want it to be a Hybrid, it's not. If you buy one thinking it's one then that's up to you of course.

Once again, the point is there is no clear definition of hybrid. You're thinking of hybrid in terms of being able to blend power sources, but there is no clear guideline that this is the correct definition.
 
I would take Segen Solar's word over Sustainable's, but like I said up to you who you think knows more about Solar Power products.
 
I asked Segensolar if the King and the VM iii, blend or switch over between pv and grid and the answer from Kyle and Glenn ( two of their technical guys ) was they blend.
I did not use the word “ hybrid “

This isn't a case of who is right and who is wrong, it is that there are multiple accepted uses of the term.
 
Blends PV and Battery. Just not PV, Battery and Grid.

Voltronic are the manufacturers of the unit, here is the original spec http://voltronicpower.com/en-US/Product/Detail/Axpert-VM-III-1.5KVA-3KVA-5KVA

Sustainable are for sure using "Hybrid" for units that are Off-Grid, the Growatt is an Off-Grid inverter https://www.sustainable.co.za/growatt-spf-5000tl-hvm-p-5kva-5kw-48v-hybrid-inverter-with-wifi.html

Even Growatt would say it's not a Hybrid because they have a Hybrid range. https://growatt.co.za/product/hybrid-inverter-sph-series/

You are getting too stuck on labels and terminology even though it has been proven that they are being used loosely. We discussed The King and the VM Iii and I thought it was settled, the King as well as the VMIII has what is called the SUB priority option, when it is selected the inverter can power from solar, if Solar is not enough it Wil power the loads from solar and utility, the other standard Axperts has only the SBU priority option, it can power loads through solar and battery.

The King/VMIII has both options SBU and SUB.
 
My Axpert has those options too. That just sets the priority.

It’s actually an easy test to make, run a load that requires AC supply and if it completely switches over to the Grid it’s an Off-Grid.

If the DC still produces with the AC then it’s a “Hybrid”.

Only by your preferred definition

The standard Axpert can run a load that requires AC directly from Solar, I am not sure what you are saying here, As long as Solar is enough it will never switch to utility.

I am not attacking you or saying I am right, I just want to talk about this and get all facts on the table.

Let me start. I have no experience with the King but the standard Axpert has the SBU(Solar+battery or utility) priority, I have seen it in action. When this is enabled Solar can work with the battery to supply power to the loads, so it's DC and DC, no option of DC and AC.

Now what the VMIII and the King has is the SUB option, does yours have this? because in theory this is supposed to blend DC and AC, are you saying it doesn't?
 
I do have the SUB priority setting, it typically used when you prefer to reserve the battery as a last resort, this is ideal if you want to save your battery for Load Shedding but in context of solar this option is for the grid-tied setups with a small backup because they might be using all their consumption during peak sun.
Perfect for a manufacturing company that wants a backup only as an emergency. I’m sure there are many other cases.

I’ve been in the situation where I depleted my UFO 4.8kwh battery because I was running my irrigation pump and pool pump in the evening, I was woken up by the sound of my alarm at 4am because my battery ran dry and it switched to grid but because it was load shedding I lost all power. I now make sure I have enough battery by physically switching to grid in the evening so the battery can charge up, I only do this if I’ve got 20% left in the bank.

The problem is that you have to set it to SUB (Solar Utility Backup) you’re kind of stuck with it, I set as SBU and manually switch over. The King will 100% do this BUT it won’t blend the AC and DC, the beauty with the Goodwe is that you can have a very fine tuned setting where you can decide that you want to reserve 60% of your battery then switch to grid until it’s back to 100% the use the 40%.

Off grid isn't connected to the grid at all.

By all accounts the King does blend solar with grid

I hear you, but what does the inverter do when it is on SUB, it is by its own definition supposed to blend AC and solar plus battery on SUB, does it not do what it claims to be capable of? It says right here that on SUB " solar energy provides power to the loads as first priority, if solar is not sufficient to power all connected loads, utility power will supply loads at the same time.

But will the Goodwe blend? I don’t want to fine tune settings albeit that’s good to know but if my load is more than what’s available from Solar or batteries I want to use Grid Power.

I’ll be honest. This discussion has confused me even more.
