Yeah, so the mud-slinging aside... The almost inevitable reverse justification for purchases always occurs... Land-Rover vs Landcruiser, Glock vs CZ, etc, etc, ad nauseum. We're all adults dealing with an adult topic. Maybe we all just need to learn how to deal with criticism without demanding a safe space. Robust debate is always good.

I'm genuinely quite interested in Hubble (despite their approach to this thread - which was to trash Pylon), for the same reason that Deye/Sunsynk leapfrogged all the other (more established) brands. That's the benefit of competition.

This thread has been illuminating for me, and not just because I learned that I need to upgrade my battery cables ;-{)}

Re cable size, I'm still confused! Is the std pylontech cable good for 4 pylontech batteries?

What does the LiBMS screen on the sunsynk show from the hubble batteries?

Hi Achmat. Once we commission the inverter, I’ll let you know.

Looks stunning.

@PaulinNorthcliff here is the part about battery cables from Sunsynk installer manual. 

3.3. Battery Connection
 Battery connection of the 3.6kW/5.5kW model
 Battery connection of the 8kW model
For safe operation and compliance, an individual DC overcurrent protector or disconnection device is required for the connection of the battery and the inverter. It is recommended to utilize a suitable fuse and DC isolator (see next page). In some applications, switching devices may not be required but overcurrent protectors are still required.
A minimum battery cable size of 35mm diameter and 50mm diameter is recommended for the 5.5 kW and 8.8kW inverter, respectively.

Thank you.

What I HAVE done is connect either each set of two Pylons to the Deye 8kW with their own 25mm^2 cable set, or connected the two banks of 4 Pylons (as per my house pictured supra) to the Mersen disconnect/fuse, and then run double 25mm^2 cable sets to the inverter.

If the smoke escapes I shall try something else.

I think you mean 35mm² and 50mm² - 50mm diameter would be challenging to crimp amongst other things.

This wire gauge thing can get mighty confusing.

So 50mm^2 is 10mm diameter copper in a 15mm diameter insulation casing,
35mm^2 is 8mm copper in a 13.5mm casing,
25mm^2 is 7mm copper in a 12mm casing.

some one asked about the pylontech warranty void scenario .
Yes its real .
Yes you must not clip the max current limit 
Doing so voids your warranty !!!
An extract from the phocos any grid installation manual to back up what the user went through !

 

And another !!!

in short if you dont use like 6 us2000 or 5 us3000 batteries you are going to risk overloading the batteries ! 
All it takes is one current peak over discharge and your warranty is = NULL.

Hi Achmat, BMS says 125A per battery so 250A for 2 x AM2s. Right now we are busy sorting out the comms between both batteries, they may need a firmware update.

From what I know, the warranty is 10yrs, not 7 or 5 years. You have 5 years standard warranty and that gets extended by another 5 years when you register your battery on their website. I will try and get my registration confirmation letter and attach here when I get a chance  

I received 7 years' warranty on my 3x US3000Bs, and a further 3 years after registering.

Sad that this is degenerated into a mud slinging & pissing match.. Unfortunately having the discussion about Victron/SunSynk etc is misplaced and has detracted from the point. 

This was a battery discussion. Maybe we should stick to that, and go have the measuring contest in a different topic.

Unfortunately while Hubble is clearing following this, its not what I would call constructive forum to answer given the rest of the fluff. (although it does seem Hubble answering selective questions, which is their right, not like Pylon-tech is going to come chat with us). @HubbleLithiumMaybe post the details in the actual product pages or in the post where you shared the installation photo's.

The useful bit I have gathered so far that is that wiring of these stacks( 4/5 bats) is something we should be a little more mindful of. Does anyone have a spec on max current for 25mm^2 vs 50 mm^2.

It is however interesting to note that there is some bias to Hubble for now all three staff picks are Hubble related.....

@Energy-Jason is there any direct links between the forum admin and Hubble? I know the power-forum-store is the official agent for at least the RIOT, any other links that we should know about in the interest of transparency? (I have no issue if so but is good to understand nevertheless).

While I will continue to follow all of these topics as I have invested in the Hubble equipment , once installed I will share my experience.

 

Now back to the actual topic of batteries

You raise an interesting point: Hubble Lithium have actually bothered to come on the forum and answered many of the questions. I don't see Pylontech / FreedomWon / BYD doing this.

They have also made it clear that they are willing to answer further questions via their official support channels. It's quite a reasonable compromise, because managing social media queries requires a big budget and specialist skills that aren't exactly the core competency of a small company that makes batteries.

Glock vs CZ? Pffft. Amateurs. Beretta is the *only* way to go.

3 months ago I was reviewing my own Pylontech decision and I felt like kicking myself for not accepting the BSL Batt that an expert originally recommended. Yet if I were to make a recommendation for a friend today, it would be the Hubble without hesitation, purely due to price performance. In another 3-6 months' time, it may be a Lithium Titanate battery, or yet another challenger.

I am very grateful for the fact that we have strong competitiveness in the storage sector, also grateful that we have such lively and active research and development in newer tech. Lastly, grateful that I will only be stuck with my Pylontechs for another 10-15 years, some of the Lithium Titanates do more than 20 000 cycles, not great for CUS 🤣

Wait for Graphene hybrid. THAT will change the world.

Very neat, well done!

Busy hooking up hubble x-100 to my infini 3k+
Does anybody know if I have to enable this:   Activate Li-Fe battery while commissioning

Or what does it do?

Thanks!

In a Slightly Longer answer the Battery Communicates in Native Axpert thus telling the inverter via the communications cable what capacity it is and also the correct voltage range charge rates and discharge rates of the battery and thus eliminating the need for the user to enter the values manually and allowing the BMS otherwise known as the Battery Management System to control the inflow and outflow of current both working in perfect harmony ensuring optimal performance of batteries interface with the inverter system attached.

Thanks, so if my infini does not connect to it via a communication cable I dont need to enable that setting? Someone told me it is to charge the capacitors on the inverter so that it does not surge or spark when you connect the battery or is that incorrect?
