Are you still in a predicament ? If so - I am prepared to assist - DM me if you need help still

I do not believe in Magic - So I would stay clear of this - The prices advertised could only be possible if the goods are stolen, goods do not exist and you will pay money and get nothing, or you get something that is not what you expect.

Hi there - Its a really nice product - really nice in a backup power scenario IMHO and where your power demands do not exceed the inverter which is only 6KVA - Does have PV Input so you can add panels on. Makes a very neat single unit install.

FYI - Kodak OG-7.2kW and 5100S battery - did you get the communication working - as far as I know you will have to use it in voltage mode on any voltronic inverter

I hadn't seen this post - but yes you can use a straight through cable - you would just need to set the dip switches for either RS485/CAN and which pins the battery BMS should output on - SW4 and SW5 are for CANL/CANH or RS485B/RS485A respectively and SW1 (1 and 2 up sets it for CAN output 3 and 4 down) or 3 & 4 up RS485 with 1 and 2 down - you gonna need CFE support to do a firmware update for voltronic - This is for comms to inverter not Pi

Make sure the CFE batteries are on default dip switch settings only the master slave dip switch set. 53.8 is bulk charge/cv voltage, 53.6 is float and cut off voltage at 48V

45.07 and panel firmware 12.13 - also see my DM reply

Nope - after3 attempts by CFE updating the firmware on the 5100s - BMS communication to inverter is erratic and causes problems - so still on manual settings

If you want to use the user defined option - the Dip switches need to be setup to default ie. SW 1 (1 & 2 up) SW 4 (CANL) 5 up SW 5 (CANH) 4 up Bulk Charge 53.8V Float Charge 53.6V Equalization 53.8V Cut off Voltage: 48V PS: ONLY change dip switches when batteries are off. This is what CFE gave to me - cos the BMS communication is erratic on Voltronic Inverters.

@Ferdie K - Are you using these batteries with a Voltronic Inverter ? If so, did you manage to get them communicating with the inverter without issues (ie. communicating works but then Warning 60 at random times, this then prompts a low bus voltage error) - running the batteries without the communication cable connected with user defined parameters and no issues

Hi So I have 2 setups 1: Synapse 7.2M+ (Axpert Max) with 2 x CFE 5100s batteries 2. Kodak 10KW (Axpert Max II) with 2 x CFE 5100s batteries So has anyone managed to get the BMS communication with these inverters ? I had CFE Tech update the firmware on (1.) - after which the inverter does connect to the battery BMS - but seems to lose connection at some point (Warning 60) and other erratic errors - when setting manual parameters and removing the bms cable - no errors or warnings - and everything works I have not had them update the second pair's firmware as I see no point at this stage so running manual settings atm. Anybody has any advice ?

Hey @Trick720 - Did you manage to get this sorted out ? - I have a similar scenario - I have 2 x 5kwh Lithiums connected to a 7.2KW Axpert Max, permanently wired to AC input - when power either fails or is restored - I end up with Error 52 - it is random - not every time. Powering off everything and on again and it all works fine again until the next time which could be 1 day or 2 days later.

Does anybody have a wiring diagram for the communication cable from a CFE 5110s to Axpert Max inverter

I agree - I almost bought these - That Model Number doesn't exist in the Narada range 45NFPC200
