Afternoon all In November 2022 I purchased 2X Hubble AM-2 120AH Batteries, these have been working perfectly since. In June i purchased another 2 AM-2 120AH batteries which were installed yesterday, exact same model. Now with the new firmware they have all been downgraded to 100ah, but the unit clearly stipulates that its 120AH. Has anyone else experienced this?

Huge thank you @BritishRacingGreen for helping me out with the repair. It’s now been in for two weeks and working better than ever. You sir are a gentleman and a scholar!

And I was just bragging how this guy had worked perfectly for 6 years.

Correct

My inverter started the same thing today after shutting down the system. Anyone in jhb that can repair?

I gave Hubble a call and they confirmed that the hld serial is the new version. Will return the other unit and wait for a replacement.

I Just received my new batteries and they are not identical, will they work together or should i return one?

Looking to sell 3X Nerada 2.4KW 48V batteries as im upgrading to 5.5. R9500 each Neg. Available in Sandton Or Westland area

HI All I have 3X Narada 50AH batteries and was looking to add more, however they dont seem to be available. 2 batteries are 2 1/2 years old and the other just over a year so dont want to chuck them out, it was also a big investment for me at the time. what are the options? i was told i cant add a 100AH version to this setup. if i were to replace them, where do i sell these?

I’m based in the west rand. Jhb

im looking to sell my 2X nerada 2.4kw 48v batteries as i need to add additional batteries and dont want to mix. These have about 90 cycles on them (will check when i get back from leave). New they are in the region of 14-16k each. was thinking around R24 for both. will only sell as a pair as they were new together

i am using the ICC software and Cable, which indicates the cycles, want to confirm if this is correct. Yes they were new and run together. is there alternative software to check? I plan either add another two batteries or sell these as a set and purchase 4 new batteries

I have 2 2.4kw Narada lithium batteries. How can I check the number of cycles done on them ?

I was looking at 2X US2000 for 4.8kWh. 1x US3000 is not enough and 2 is out my budget

its the RCT AxpertMKS 5K/4000w with 60A/ 3000w solar mppt

thanks i updated the OP with extra info

im in Ruimsig on the westrand, JHB. i have the axpert 5kw inverter , also looking at solar panels

Where is the best place to get the 2X Pylontech US2000B for my Axpert 5k 48 inverter? i would prefer for them to be installed so there is no issue with warranties on the bank Im based in the west of JHB. Id also like a recommendation on Solar panels. My average usage is around 300-400 watt(my house power loads have been separated) and would like use solar during the day to power the house and charge batteries.

my plan is to add solar panels, thats been delayed now as i need to use those funds for the new batteries

No this one https://batterydistributors.co.za/product/narada-48npfc100-23/

So i have decided to replace the batteries. i had them tested and 4 failed. the 4 im currenly using are not giving me enough to last thru load shedding. im looking at 2 options- 1. nerada LFeLI-4 8100C 2. 2X pylontech US2000b. does anyone have any experience with these units?

i have already got the quote from them, just waiting for payday

NO, the positive and negative from inverter run to the first string and then a loop to the second.

That battery is definitely dead as it wont charge over 11.5 volt. id like to test the other 3 in the string ,How would i load test them @ 300 amps?

all interconnects in strings are same length using 35mm cable. is that cable ok?
