    Hey Mornek, Good luck trying to get a answer from BLSB. They took four and a half hours to answer, "Can I install the two BLSB upright", yes or no, Just now they say the warrentee is not valid you installed horizontal. All I got was please call back later when I called and they did not answer. Did not respond to any further sms, whats app, phone calls. Email. Just ignored me. All I want was , yes , no. Utter poor response.  That said, Let me help you as you dont want to go through the total regret I have that a company can give such poor service on such a costly items. I have two 6.4. The dip switch on the 1st one is up namely one, and the 2nd the 1st is now down but the 2nd is up, namely two. You also need the  RJ45 cable between the two at the last connection to the right. RS485

    Hi Ryan, sorry to hear about your bad service today. Was the company you purchased you purchased these batteries from not able to assist you? I see you have answered the question above quite well. If you need any more information let me know - [email protected]

    Hi. I have contacted my installer. He has seen this before on an installation with 5 BSL batteries. At some stage those batteries have discharged to 0% and shutdown. After they have been stated up and charged again the problem was gone.

    After checking all possible settings we decided to discharge this battery also until it shuts down. We did that, reset the battery and started it up again. 

    The battery is much better now but not up to spec yet. Before the BMS would limit the max discharge current form 105A to 30A anytime it discharge at a rate in excess of 50A.

    Now the BMS will limit the discharge to 30A as soon as it discharge at a rate  in excess of about 75A (3800Watt). If it is according to spec it should be able to discharge at least up to 100A (with a max of 105A)

    Hi Daniemj

    Thanks for these and I can suggest a few changes on the settings. If a reset on the battery didn't solve the problem completely, a second reset might work. Otherwise we can get the battery back in for a firmware reset.

    Would you please get your installer to contact me via email at [email protected] and I will discuss some aspects with him for your installation and any further installations he does in future.

     

    regards

    Hi.

    We have installed a 8.8KW Sunsynk Hybrid inverter with a 5.1 Kwh BSL lithium battery. The system was running perfectly but it has developed an interesting problem. For the second time now during load shedding at night (battery only source of power), the BMS of the battery changes the Discharge current limit from 105A to 30A. Then, as soon as the load goes over 30A the inverter drops the load in order to "protect" the battery.

    Once the whole system is shut down and the battery is reset, it displays the correct value of 105A. Thereafter the system operates normally again (for a day or two until next night time load shedding) 

    Any suggestions as to what could cause the battery to change the Discharge current limit (during load shedding)?

    Hi Daniemj

    This is interesting and not something I have seen before while working on the BSL's. Have you contacted your supplier regarding this problem?

    What are your settings on the battery? Please could you provide me all the screens on the battery setup menus? I work mostly with BSL and Sunsynk, I would just like to check a few settings out first. Next step if there aren't any issues there, is to contact your supplier for support and see what they are able to do for you regarding checking the BMS on the battery.

    I can do the backup support on the battery if your supplier is unable to help you, please just let me know.

     

    Regards

    Frankly, in 5 yrs time all the batteries we have now will be "old fashioned", in the same way as Lead Acid is so yesterday,  today.

    If we assume that the battery technology is pretty much the same across brands and that a BMS is not a unique item on a battery then it comes down to after sales service and the batteries ability to "talk" to the inverter.

    The other issue with most battery buyers is we buy what we can afford today and then hope to buy more batteries later on.

    With the pylontechs, I have just bought another battery, not because I needed it, but because they are upgrading so quickly that in the future the newer battery may no longer be backward compatible with the 3 I had previously...Its a case of buy now or the batteries in the future will not be compatible with the current setup..

     

    This is a very important point and something that needs to be addressed by more manufacturers.

    With the BSL, no matter what has been physically done to the battery and how the internal setup has changed, there has been a drive to make sure that all the batteries within their range are comms capable and able to be paralleled with each other. So the older 5,1kW battery is able to integrate with the 6.4kW battery, this is because the current BMS and firmware are setup to do so. This is of course over a one year period. Further down the line and as advancements in technology come, there might be issues here but that is unfortunately something that happens with technology. You can't compare or swop parts on a car model from ten years ago to its current model now.

    So we all need to be aware that the market will forever be shifting, new chemistries and technologies will always drive advancements and we need to keep up with this. Making sure the brands who stay ahead of the curve are the ones to support and watch in the market becomes a future grow point for all our businesses in ten years and we grow the industry in a world leading way with the best for the market in mind. If you are going to keep supporting the people who are on the same loop all the time, you can't complain later on when everyone else is miles down the road and you are stuck in the same loop.

  5. A very interesting topic here and happy to put my two cents in. I have my own opinions of Pylontech batteries, this is not the platform to air them though. I prefer to make sure that people can get a better understanding of the products they purchase.

     

    We supply and I do the support for the BSL battery, what you have all come to know as the Bull Battery, and I am involved heavily behind the scenes with the battery and manufacture of it. A few of you I recognise as people I have actually dealt with and personally helped in setting up systems with the BSL's. We can guarantee the battery in our efforts to always improve and maintain a very high standard when it comes to the product. BSL has made sure that not only is the product of a high standard, but also that the after market service is always available, giving you peace of mind that there is always support when needed.

     

    The BSL's BMS is robust, heavily tested and our efforts to make sure of comms capabilities gives us a little edge over some of the others in the market. No battery is ever perfect and they all have their pros and cons, but those manufacturers who put in the effort to better their product continuously will always be a better option than companies who give you something they say works and don't offer anything further than that. Over the past six months that I have been involved with the BSL, I have seen the engineering and updating of the batteries first hand, watching them evolve and advance with the more we learn. Learning is a key aspect of the process and giving the best is always the goal. 

    We always maintain the ability to replace any part of our batteries if the need so arises, so that aspect is taken care of.

     

    As for cycle life on batteries, please don't use this as a given on any battery. No manufacturer can tell you exactly what their battery will do over ten, fifteen or even twenty years, not in a market that is so new in comparison to other markets who have been around for far longer. The biggest problem is that people expect electrical engineers to tell you what chemical engineers actually know.... So there is still much learning and the future will be even more interesting. The BSL is rated to 5000 cycles at 80% DOD and comes with a ten year warranty as standard, but the design life is actually 20 years and the cells will obviously last accordingly to your usage and exertion on the battery, as with any battery.

     

    I will be doing some testing on other locally available batteries, I am very keen to see what the market has to offer and how they all compare, this is one of the goals we have for this year. As for Pylontech, they have their place in the market and they aren't going anywhere soon, just bare in mind that companies such as Hubble and BSL are always making advancements and they offer the local support which you won't get from some other big brand names. 

     

    Hope you all walk away with something from this thread today

    Will this work with an existing battery? Can it be used for expansion of existing storage?

    Hi Dname. You should never mix different batteries, especially not Lithiums. So in short the answer is no, if you are going to try upgrade an existing system, then please add the same batteries as you have installed or replace the batteries all together with new ones of the same make. Our 5.1kW and 6.4kW batteries can be mixed and matched between each other but that is because they have been designed specifically to do so.

    Will these batteries work with my older Axpert and the Centurion solar setup I have, like the Pylontech batteries do?

    Hi Shaun. They will work, but only on voltage settings and will not be comms enabled. We do have them out in installations with these types of inverters and can supply you with the correct settings for the inverter on request.

    Slightly lighter but marginal and yes no fan attached. The 3,6kw must be kept in cool garage or room well ventilated. The 3,6kw won't come with fan as it is not high performance in the sense that the 5,5kw can handle more loads meaning the 3,6kw is used for entry level small applications. Sunsynk concludes these low level requirements don't constitute the need for a fan but in my opinion it should still have one.
