I'm looking at a basic setup with a SunSync 5K inverter and want to add a 5k battery. I've looked at the Hubble 5.xkw AM2 or AM5 and the Greenrich 4.95kw

I have 2 main questions...

1. Hubble has a 1C rating while Greenrich has a 2C rating. From what I understand the Greenrich would charge faster (twice as fast) and accommodate load spikes better?

2. The DoD, discharge, the Hubble says a lifecycle of 6,000 cycles at 50% while Greenrich is 6,000 cycles at 80%. Am I right in saying I can use more of the Greenrich battery (up to 80%) and have the same lifespan of 6,000 cycles from Hubble?

Based on the above would Greenrich be a better option to Hubble? Is there something Hubble offers I'm missing? They are a few grand more expensive than Greenrich from what I've found.

 

Thanks

Personally I think Hubble has been marketed better as compared to green rich I prefer the later

 

 

It's all about marketing, isn't it? There is no 6000cycle or 10 year data by any user for these batteries.
You either believe the marketing or you don't and in the absence of that, you have to go with the fan boys, feel happy and promote that which you paid for. 🤑
Or not?

I doubt it's a steady 2C. Maybe for a minute each hour or something like that. 

Freedom Won say their CELLS are actually 3C, but their BMS won't let you draw that sort of power for even a short time. 

Thinking about it, if you ran two "2C" batteries in parallel, you'd need some big ass cables, no?

I have personal experience of two brands of battery. That's not 10 years worth in either case, but I would definitely recommend one of those brands against the other, and I can tell you why. 

I'd have to qualify it a bit because one brand is significantly more expensive than the other. So there'd be an element of what the other person can afford or what their criteria are.

Nothing beats own personal experience. There is no substitute for a direct comparison when all other factors remain equal. 👍
 

No personal experience of either battery, just stating the obvious that 1C vs 2C is irrelevant if you're using it with a 5kW Sunsynk that can only handle around 100A charge and discharge rates, effectively the normal limit of what a 1C battery can delivery. The inverter remains the bottleneck, not the battery.

At least on paper the Greenrich with 6000 cycles down to 80% capacity promises superior capacity/performance compared to the Hubble.

That's very helpful, the inverter being the main bottleneck regardless of C rating. Thanks.

Thanks everyone for the feedback, no clear winner between the two.

Are there other brands I have overlooked? The Freedom Won seem like they're for a different tax bracket, not sure who else would be reliable/trustworthy brand wise.

I am having a look at batteries too and would really appreciate if you could share which two brands and which one you would rather choose and why?

This is all available on this forum if one digs around.

Revov & Freedom Won (specifically their LiTE range). 

The Revovs were the original. I was unhappy with them from early on, but also it occurred to me that hey! maybe this is just the way that solar life is. Maybe you need to tolerate the semi-regular glitch and have to do some resetting of the equipment. I didn't know. These were the only batteries I'd had in this application. You can read more detail here.

NB! This was an early Revov model, not anything shown on their website now. But I suspect only the packaging has changed. Certainly that BMS is what I had, and the specs have not changed.

One consequence was that for nearly 3 years I was in regular contact with the installer, who must have found this frustrating but, to their credit, never brushed me off.

Eventually a decision was made with the installer to completely change the batteries. He didn't give me a lot of choices, in fact he really only gave me one. He said it would have to be BSL or Freedom Won, but BSL didn't have great comms with my inverter and because he wanted to put an end to all of this it was really only Freedom Won.

NB! This is the Freedom Won LiTE 10/8. Please don't ask me about the e-Tower, I have no experience with that.

So the day dawns, the technician arrives. My first impression is that the Freedom Won is much more self contained, more compact, doesn't need racking (you can mount it on a wall if you want, but it is really a free standing unit), doesn't need extra kits of leads. So it's a much easier install than the Revovs had been.

Then the tech phones his boss to check the settings on the inverter. I hear him repeat back "default lithium". He sets the inverter into this mode, plugs in the CAN cable and the FW takes over and sets the inverter just the way it likes it. This takes seconds. The BMS has now told the inverter exactly how to behave and what it wants.

And that was 9 or 10 months ago. Since then the system has been rock solid reliable and stable. We sailed through Stage 6 load shedding. No more funny things happening with the batteries, no need to restart anything. It just works - all the time.

So you can google the prices. The FW costs more, and not by the odd R50, but my experience of living with the two is as different as the prices.

PS. And the installer doesn't hear from me anymore, save for a message to say how much better things are working with the Freedom Won.

Thank you so much, this is very valuable, much appreciated.
