I do exactly the same. It would be really nice to have a way to query what your outstanding fees are and also just settle that amount every month. I dont need the 62.5 units per month, its accumulating now as I'm over 300 units and growing... lol

Is there a way to determine your outstanding service fee?

Certainly not. My Pylons US2000B, US2000C & US3000C's are hooked up on my old Axpert 5KVA inverters without any comms cables.

Here you are... the latest I managed to find for both old and new chip. From the bin file for the new chip(v2.2), it just seems they refactored some code, so no major changes from v2.1. I noticed there is also support for UP5000 as well on these versions. US_C_stV2.9_NTV2.2Crc.zip

There are 3 commands that you can try: socclr clear bq34z100 data flash and reload default value - socclr statc Clear statistic - statc datac Clear data - datac [event/history] The easiest would be to re-flash the firmware even if its the same version but ensure that the "Clear EEPROM" box is checked before clicking "Program"

Hi all, Just purchased a new US3000C to add to my bank and it has the newer chipset with v2.2 firmware on it. Does anyone have this firmware file as I see the effekta link below only has v2.1 https://www.effekta.com/download/firmwareupdate-for-us2000c-3000c/

i would recommend the FTDI chipset for those cables. Don't use a cheap cable, they are not reliable.

I'm interested to know the difference as well. Any update here?

Item: Axpert 4kw/5kva x 4(Various brands but all compatible, they are not the clones/knock offs) Age: from 2018 onwards, I did not purchase them all at the same time. Price: R22k for all 4 Payment Method Accepted: EFT Condition: Good, all in working order Location: Jhb Reason: Upgrade Shipping: At the buyers cost and risk. Collection: Yes I have 4 x Axpert 4kw/5kva inverters. I currently only use 2 of them in parallel and 2 are backups. All are fully functional with the latest firmware from the Australian forum. They all have parallel cards in them and i have all the relevant cables required too. The 2 in use are paired up with my Pylontech battery bank. Looking to upgrade to a Sunsynk inverter. Any takers? Willing to accept R22000 for all 4. Please PM me.

Thanks! Looks like v2.1 is for the 2000C/3000C using the newer chipset. Would be nice if Pylontech issued release notes...

Identify the cells which are unbalanced with BatteryView then manually charge those cells(2 pouches make a cell) using a 3.7v charger with 1.5A max then add it back in. Assemble the battery again and test.

Thank you @Tinbum, your guidance has worked.

Batteries 8, 9 & 10 are the US2000B models and are at end of the pack...but after reading the manual again... you may be onto something. The below is from a US3000C manual: @Tinbum, you reckon if I shift the US2000B's into position 6, 7, & 8 then i should be good to go? Basically invert the order of batteries in the left cabinet and make the US3000C battery 9 and the US2000C battery 10... This actually makes sense now as the US2000B's only ever accommodated 8 in a single group... Lemme try this. PS: Note to self, don't commission new batteries into a pack at midnight!

This looks like the correct thread to add my issue to. I too also have mixed Pylontech's in a single group but having issues when I recently added 2 more batteries to my existing pack of 8. I may have stumbled across a new issue. I had eight(batteries 3 - 10) in the pack but recently I have added two more batteries to my bank, totaling 10 modules now. Battery 1 and 2 are the latest additions. Below is a pic of them. Numbered from newest to oldest. Batteries 1 - 5 are the US3000C running the newer chipset and all have v1.8 firmware loaded. Battery 6 is a US3000C running the older chipset with v2.8 firmware. Battery 7 is a US2000C running v2.8 firmware. Batteries 8-10 are the US2000B's running v3.4 firmware. The manual always says that your newest battery should be the master which is how I have configured it but when you start the master(1) battery up(SW), it starts up each battery but when battery 9 is reached, it seems the BMS is not capable of dealing with more than 8 batteries in a single group even though the manual says that the C model battery can handle 16 batteries in a single group. All LED's on Battery 1 - 9 flashes and it attempts to restart each battery again. Battery 10 does not even start up. Unfortunately the battery pack does not start up and I can't even connect using BatteryView. I attempted to use Battery 6 as the master as it's using the older chipset, slaves starting then from 1 - 5 and continuing with 7 - 10. The same issue when reaching battery 9 as my previous point. I also then tried using Battery 6 again as the master but the order of the slaves are starting from 7 - 10 and continuing with 1 - 5. This seemed to have worked but can't connect to BatteryView for some reason still. Also this goes against having the newest battery higher up in the pack. At the moment I have disconnected Battery 1 and 2 like I had before so that I can continue to use my pack. This seems to be a firmware issue as I have double checked cabling and all is in order there. I even tried running Batteries 1 - 8 and there were no issues starting them up. This makes me believe that the firmware on the newer chipsets of the US3000C does not accommodate more than 8 batteries in a single group. I have emailed Pylontech and awaiting their response. Has anyone else experienced a similar issue?
