  1. Hi Andrew It is unfortunate that you had such a bad experience with us. The standard procedure is to return the BMS, we inspect it and replace if needed. We test every BMS that goes out and make sure the connector on the PCB is not loose. From my understanding the connector was loose, how this could have happened, I don't know... This is then clearly physical damage. We did ask you multiple times to send in the BMS but you never did. It would have most likely ended up in front of me for validation and I would have just soldered the connector back. Please do in the future handle the products a little more carefully and if there is an issue send it in and we can asses it. I believe we are reasonable otherwise we would have had allot of customer complaints all over the forums and allot of bad reviews. Kind regards, Bain Viljoen
  2. The BMS can only control power in and out of it the cells, would be impossible for it to trip the input breaker of the inverter, Batteries give power, if the inverter is not handling that power correctly then its the inverters that is the problem.
  3. O and set low voltage cutoff to 46v. Back to AC voltage to 48v maybe. 48v is 3v per cell, almost completely drained.
  4. Maybe I am not educated enough with the inverters, how is a BMS disconnect tripping the AC input breaker?
  5. I cant remember what those setting are lol, assuming it is bulk and float and low voltage cutoff. Bulk + float to 56.4 as I have seen the inverters stop Charing before the battery is satisfied and reads a full charge. I'm assuming the BMS cuts the Charge off as there is to much power as both inverters are trying to charge full power.
  6. This is perfect if you want to leave some reserve for incase there is load shedding. Otherwise take it down to 10% or even 5%, hell go down to 0 if you want hahaha, not advised though as you want to avoid a disconnect between the battery and inverter.
  7. Don't worry about the cycles, as soon the battery hits 80% it counts a cycle, charge a little bit and drop again to 80%, another cycle. That's why we don't base our warranty on cycles but years. The cells rating is 7000 cycles full discharge and charge at 0.5c so don't stress to much, utilize the battery or else your not saving on your power bill. Also another thing that will make the cycles stupid is working of voltage as it keep discharging that bit and charging a bit. The 56v is a conservative value, only 3.5v per cell. If you use 4kwh per day from the battery over the life of the battery you will be saving well over 100k on power if calculated at 3.5 bucks per Kwh and the battery won't even be at end of life. So USE the battery and save on your bill, that's why you got the system in the first place I believe? So set your bulk and float to 56 if not running with CAN coms My suggestion, do coms, set back to AC at 15%, low SOC cutoff to 5% and back to battery at 30%.
  8. Hi @Antonio de Sa, Mine is also set to SBU and OSO, retarded inverters don't give a damn.... Also, 30a breakers is only 6.9kw of AC, so easy to overload with 2 inverters and a battery charging. If you have sufficient power you will be able to charge the battery to 100% (will only briefly stay there as a few mA will take it down to 99%) Try using the coms cable, will give you a better experience and setting cutoffs with % is better than working of voltage. Use Program 52 under lithium protocol.
  9. @Antonio de Sa also to note that you have 2 inverters connected to 1 battery, Max power draw from the inverters is > 10kw and 1 battery cant handle that. Another point to raise is that The inverters are "Dumb" The battery says it needs a certain charge current, the inverters each try to charge at that current effectively over currenting the battery. Now according to your panel power available this is fine, but as soon as you try to charge of the AC and the growatt will as your 1 battery will most likely not last thought the evening. My 2 inverters trip all breakers leading to them in a random order if it goes into bypass and also starts charging the batteries. The 20 seconds that you mentioned supports this analogy as this is about the ramp up time of the AC charger.
  10. Hi @JoeyhZA and @Antonio de Sa Unfortunately I cannot help, I imported a few SACOLAR inverter (basically the growatt ES) The aftersales service I received was atrocious to say the least, been begging them for months for inverter boards and eventually I had to pay for new inverter board even though they are warranty claims. Even after I paid I had to keep begging them, telling them that my customers are pissed at me and inadvertently my service. They just keep saying they don't have stock, basically it is more important to them to sell more units instead of aftersales support. Eventually it just came to a point where I offered all the customers a refund if their inverters popped. I would never in my life recommend a growatt/sacolar inverter to anyone ever again. Unfortunately the fact that the AC breaker input trips is not a battery problem, HOWEVER, try turning the AC output breaker off. this is what happens with my system at home. The growatts ignore the commands not to charge the batteries from AC, they start charging from AC at max power and power your house in bypass mode and the result is an overcurrent on the AC input breaker. At my house the AC input breakers are always turned off, if my batteries get flat i switch over to Eskom manually and then the next day when the batteries have charged and I get home from work I flip back to the inverters. Hope this resolves your issue. If you have the bucks for it, get a LuxPower inverter/Same price range as the Growatt, recently tested one, man o man, what an improving of an inverter over Growatt. I actually listens to you if you tell it it can only charge of AC at 1a for example, also has allot better monitoring and the settings of the inverter over the web are actually allot better. With the newest firmware update of my battery you can get the AH of all batteries connected in parallel also displayed on the inverter.
  11. Hi @Vaal, That was actually a response to another user that was extremely rude, so rude that the moderators deleted his comment, that should say plenty about the quality of the other users comment? I was simply asking why the battery was being sold and then I get a sarcastic and rude comment from a user that has nothing constructive to add.
  12. Great, thanks for the positive feedback!
  13. Yeah, if your inverter has CANbus then even batter, it will ensure all 3 get charged fully.
  14. Thanks for the positive feedback. These are new cells yes, I state on the 2nd life units that they are 2nd life. Transparency with clients are important, this way the customer knows what he is getting!
  15. My business is that I manufacture these batteries so I take any problems with my batteries very seriously, I do my best to keep my customers satisfied with my products. If they are unhappy I would like to know why so that it can be addressed and in the end have a happy customer. Satisfied?
  16. If that is the case why was something else bought in addition to LBSA instead of more LBSA?
  17. So you just buy things blindly? I thought all people on this forum were intelligent and constructive, guess there's an exception..
  18. As @GreenMan suggests, LBSA batteries do communicate with Victron Beautifully.
  19. Hi As @GreenMan suggests our DALYs with Custom firmware has CABbus communication with Sunsynk inverters.
  20. Thanks for the info, unfortunately it did not work
  21. Hi, I would like to know if anyone can help with what the default password is for the sinephone app to change my inverter settings with the app. Please see attached images.
  22. @Lindsay At the moment the smart battery has coms to Victron inverter and possible SMA. Growatt, Goodwe and Sunsync support are coming in about a month or 2. They can Parallel upto 16 units together. I have sent the guys at @ICC information with my protocol for integration and await their response. Voltronics/Axpert are not willing to play ball and answer any of my emails. So unfortunately no integration with them any time soon.
  23. Thanks for all the good words guys @Krokkedil and @Gerlach @Lindsay The 6kwh unit 24V is also available.
