Strange that you Blame Hubble for trashing Pylontech.. I have read all the threads and there is not one post by Hubble saying anything about Pylontech... Leshen which is a member of the forum here compared the batteries interesting how you blame a Brand for opinions of individuals.. so much emotional responses with so few facts from a lot of people here that says a lot and don't actually know what they are talking about... besides the thread went completely off topic. Besides a battery manufacturer does not specify recommended cable sizes the Inverter Manual normally specifies and recommends the right battery cable size based on the potential current draw and charging current capabilities of the inverter or MPPT connected to the Battery... You can have 50KW of battery but if your inverter is rated at 1KW then the recommended cable size would be dictated by how much the inverter system can draw from the battery at any time.. 

Well said Boerseun.

Hi Community,

Seems the forum is decending into just degrading brands and negative commenting which is very unfortunate, as the powerforum is a great wealth of knowledge for power backup and solar enthusiasts. 
We're not dodging questions, we dont live on this forum, and we are not affiliated to powerforum. Seems if we dont answer questions immediately then there are negative views. We only check this forum once a week if that. If you have questions please contact us through our official channels or on our website contact form.

For support and technical questions please contact us direct through our official channels, we will be more than happy to assist our clients.

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?

Some of us were actually looking to BECOME clients imminently, so was hoping for more information to fill the gaps in the marketing material (Not just by Hubble, but by ALL battery manufacturers). It benefits the whole community when a business answers on an open forum - it gets rid of the he-said / disembodied-voice-of-capitalism-said debate. My questions would be the same whether you answered them here, or by email, or by carrier pigeon. I was hoping to save you the trouble of answering multiple other people too by posting here, since I saw you following the thread and I understand that businesses often don't have time to respond to every enquiry individually.

You've got a very odd position here now that I don't understand... You've taken the time to tell us you don't have time to tell us anything? No problem, we'll find our information from other sources - god help us all.

Have a look at the manual that Leshen posted a few comments back - that is clearly what they recommend for 100A (120A Peak). And a "125A or smaller" circuit breaker

Another Hubble/Sunsynk Installation. 

[Brani 32]

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.

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.

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.

[PaulinNorthcliff 69]

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.

Well spotted @P1000

It's copy and paste from Sunsynk manual (maybe the square symbol got lost).

[Zimnismoboy34 14]

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 !

 

[Zimnismoboy34 14]

And another !!!

[Zimnismoboy34 14]

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
