It's also not a hybrid only an inverter with mppt. You really can not compare that to a Sunsynk.

I am not comparing it to a Sunsynk? I reckon that the Sunsynk is a great inverter.

Look at the statement that was made then you may comment again.

Is this inverter available in South Africa?

I think you need to check your facts again, this isn't a Hybrid inverter, its an off grid inverter.

Jip that's what I meant it's not a hybrid, I did notice the 450VDC.

I think you are the one to check your facts before posting.

Maybe understand the definition of a Hybrid inverter and understand my post before you defend Victron with false statements.

My Victron acts as Hybrid. Or am I missing a point?

Victron is a grid-tried inverter. It can only power essential loads.

Ok let me understand. What can Sunsynk do and Victron can’t?

Having said that, I think Sunsynk is a great inverter for money spent. 

Sunsynk inverters are hybrid they can supply power to both essential and non essentials loads. Cost wise Sunsynk is a fraction of the price.

@HubbleLithium

Some interesting facts in this already, but I hope you can share some more info since there seems to be quite a debate raging on here. It might be a good chance to hear from you, a manufacturer, so we can make an informed decision. You know, before we all rush out and just buy the colour battery that matches our eyes  

- I was under the impression that lithium cells can deliver a lot more than 1C, so if they're 120AH cells then wouldn't that make a 150A BMS... underspec'd?

- It doesn't sound like you make the BMS board yourselves, is this a 3rd party unit that you've integrated?

- You've had some issues with the LCDs (They look like just 12864 boards similar to those you find on 3D printers?). Do you have plans to upgrade this in near future? Or is the best recommendation for reliability to rather get the unit without an LCD?

- How many units have you supplied, so that the "no failures to date" claim can have some context? And how long have they been in service?

- I'm confused about the conditioning you mention, every 6-8 months. How does one do this? I thought the main selling point of lithium batteries was that they didn't have such a "charge memory"? Can this not be built into the BMS, if it's important for retaining charge cycles?

 

Hope it doesn't sound like I'm against Hubble batteries - I'm just trying to find out a bit more about them, because I might need a couple of new batteries in the near future, and I'm weighing up options  

 

Hi P1000,

 

Alot of questions. Im going to make it short.

1. I only know of 1 company in SA that makes their own BMS, we looked at this but it's just too expensive compared to industry leading imported and international certified BMS units.
2. No charge memory but if they drain flat they damaged.
3. Our BYD and CATL cells are rated 2.5C. You can discharge and charge them at 2.5C but their life goes down a bit and there is no need to have 250Amp drawn out of a 48V system usually. We can install a 2.5C BMS, but it will increase the cost of the battery way too high and will be out of market related prices. If we do this then there is no market to sell to.

Further to this we are testing and developing a 192V, 3C, 192V lithium pack. But this is still a year or so off. This is more for UPS enviroments for short high power demands.

Having said that, I think Sunsynk is a great inverter for money spent. 

The best definition for me as to what a Hybrid inverter is, is that it can work with or without batteries. While the Victron cannot work without batteries a Sunsynk can.

Yes they cannot in a "HYBRID" inverter... The best we South Africans know is a 250v MPPT. I love how the Victron fan club defend nonsense, read the fine print regarding the MPPT - MPPT operating range is also constrained by battery voltage - PV VOC should not exceed 8x battery float voltage, e.g. a 50V battery voltage maximum should have 400V maximum PV array. – see product manual for further information. That RS Smart Solar that you quoted, is that a Hybrid inverter?

There's a bit more to it but there's lots of information about the Sunsynk on the forum.

So is this a Hybrid? Yes No? Is it available in SA Yes No? What does it Cost ? Axpert also makes a 500v Mppt so nothing new but the discussion is really about Batteries 😀 not an Axpert Clone..the Axpert can Do 7.2KW tbh the Axpert has better specs and its cheaper..

Hi Jaco. Does this inverter have a grid input?

Quoted from the Vicron website...

Off-Grid solar inverter

The Inverter RS Smart Solar 48/6000 is a 48V 6kVA Inverter with 450VDC 4kWp PV input. It is used in off-grid solar applications where AC power is required.

I think we've already concluded that this is not a HYBRID and also currently not available in SA. Also not on the COCT approval list.

Exactly that, seems like another Victron fan that debates without the facts.

What exactly do you mean by "Hybrid"?

A Hybrid inverter is one that primarily can blend Grid AC input and PV and/or battery input and supply that to the load. For example, take a Goodwe, Solis, Sunsynk, Fronius Gen24, Infinisolar, those are single units that have the ability to do all of that, each with a high voltage MPPT and battery input. For a Victron to achieve that, you need to have a battery inverter ie the Multiplus or Quattro, MPPTs and Controller, to achieve all that a true Hybrid can. This would cost 3 times as much. Now the Victron guys will argue this and say that an Easysolar is a hybrid however an Easysolar is just separate components packed together in a steel box to make it easier to install.

Jaco, once again you misquote Victron manuals only to misinform the public. Yes it has a 450w MPPT, but it’s far from being a Hybrid.
How about you show me which Victron 8kw  Hybrid inverter can compete with a Sunsynk 8kw? Or does it not exist?

I am showing you the error in what you said about the MPPT, I am not saying anything about any Hybrids, but to be honest, I did not expect you to understand.

Yet it can be achieved. Not sure about 3 times as much, but definitely much more expensive. Modular approach always costs more but gives more flexibility. 
 

 

How is that different to any other hybrid? They are also in one box and have the same components inside.

Just claiming a brand can’t do something because you dislike it, doesn’t do other brand justice. Both brands of inverters have a place in the market. 
 

We are still waiting for Hubble questions to be answered 

Well these are just prices that I searched on Google. 
1. Sunsynk 8kw Hybrid Inverter R33000, 10400w MPPT. 

2. Victron 8kw Quattro R57000

3. Victron 250/85 4900w MPPT R15499 x 2 

4 Venus GX R5100

Victron totals to R93100. 

I didn’t even quote the thicker solar cable required due to the low voltage MPPT and all the comms cables. I think R33000 vs R93100 is significant. Almost 3 times as much. 
 

Easysolar is different in that it was an afterthought. Take a company like Fronius, who never had a Hybrid inverter and due to new technology, they have developed the Gen24. They certainly didn’t do what Victron did. Do you really think it would be ok if Sunsynk took 2 x 8kw Inverters and stuffed it into a metal box and called it a 16kw single phase inverter?
 

Goodwe is a great brand, which I owned but it cannot be paralleled. That’s just fact. Doesn’t make me dislike it. Go read my post carefully before you misquote me. I never said I disliked Victron. I said I understand the limitations of each brand including the Sunsynk I own. I certainly won’t get defensive if someone said that a Sunsynk’s fans are too loud or that the SOLARMAN app isn’t that great.
