Please note that the UTP cable that came with the inverter is a standard ethernet cable for many of us Axpert King owners me included. The custom cable had to be crimped using the pin-outs in the attachment. I've shared this in multiple threads, seems people struggle to find the information when searching Many people are struggling with this. Do these forums support sticky posts?

Answered in other threads already. Search for "Pylontech US3000 to Axpert King 5K - How To???"

Have you tested the Pylontech BMS integration via the new Axpert King and VM III inverters to determine how ICC would compare? Apart from extended monitoring capabilities, would there be any further optimisation by using ICC, such as extended battery backup time without reducing battery lifetime?

Has anyone managed to get a wifi module working with an Axpert King? Would this be recommended instead of the Centurion Solar ICC module for monitoring?

Does the ICC solution work well for monitoring real-time usage from one's mobile phone? I have an Axpert King connected to Pylontech batteries with the custom cable, so that is working as it should, but can only monitor when physically standing in front of the system. Or is anyone aware of a wifi module for the Axpert King?

Hi Everyone. I'm considering adding 1x US3000 to my 2x US2000 batteries. Per the document shared by @Nicholas, I would use the 3000 as the master. Management will be done by the Pylontech BMS via the right cable to my Axpert King inverter. Noticing the experimentation above, has mixing the 2K and 3K ranges been working for you all in the long run? Anything I should look out for?

Only a pleasure @Jay-Dee, glad it helped you out. With setting 5 = PYL, are you able to change setting 29? Mine seems to be fixed to 47 volts after setting battery type to Pylontech. I was hoping to lower setting 29 a bit to 46 volts, as I understand that would extend the battery run time, perhaps at cost of longevity. Not exactly sure what the effects would be though, are you perhaps familiar with this? As a workaround one could switch setting 5 back to USE and customise, but I feel more at ease with the PYL BMS settings.

An update to anyone else who may be struggling with this, apply the settings above as provided by @Coulomb, in that order. In my case the order did matter. Initially I enabled ECO mode and bypass was disabled. After enabling bypass mode, when entering ECO mode the power would cut out, as if bypass was still disabled. Here are the steps I took go get it working: 1. Disable ECO mode (10 = AUT) and disable bypass mode (23 = BYF) in any order, then exit the settings menu 2. Enter the settings menu and enable bypass mode first (23 = BYE) 3. Now enable ECO mode (10 = ECO) As a result, my Axpert King inverter is running cool and quiet while there is utility power available and switches to line mode to provide backup power when there is no utility power.

Thank you @Coulomb. Having now tried that, the power cuts out when bypass is supposed to be activated. On the inverter setting 23 = BYE but when using the Watch Power app to examine the settings, bypass = disabled and it's not letting me enable it. I would trust the direct feedback on the inverter LCD panel over the Watch Power software for sure. The behaviour of the power failing when bypass is required, is however synonymous with bypass being disabled. As a next step I will try setting 5 = USE (instead of PYL) and then apply the settings you suggest above and test again.

@Jay-Dee, I'm a new inverter user and have been struggling with the same thing since having my kit installed yesterday. Managed to get it working today with program 5 set to PYL on my Axpert King and the battery icon flashing on the LCD panel to indicate successful communication - no error codes. You are right in saying that the black cable supplied is a standard ethernet cable, I also got one of those. Don't bother moving your kit to test it. Basically I made a cable per the attachment, using only 2 pins per side. Then it still didn't work until I lifted battery dip switch 1 to set the baud rate to 9600 - not mentioned in the attachment - found somewhere in these forums - grateful for that Now I have comms between my Axpert King and my Pylontech US2000 batteries. Hope this helps for your 3000 batteries as well. Pylontec Axpert VMIII-KING Configuration (used for cable, set battery dip switches to 1000).pdf

Well spotted re the lead acid batteries in the use manual. Could it be an entry inherited from an older version of this or another manual, that was never updated? As of yesterday I am using an Axpert King 5K inverter with 2x Pylontech US2000 li-ion batteries. This seems to be a common pairing and given the attachment I've included here, one that Pylontech supports. I made a communication cable to run between my inverter and batteries using the instructions in the attachment. The only thing it omits, without which the cable doesn't help, is that one has to lift the first dip switch on the battery to set the baud rate to 9600. I found that piece of information on this forum somewhere, which is how I signed up Pylontec Axpert VMIII-KING Configuration (used for cable, set battery dip switches to 1000).pdf

Hi Everyone. I'm new user and trying to find my way with configuring my first kit, comprising of 1x Axpert King 5K inverter and 2x Pylontech US2000 batteries. Are there any Axpert King owners around here that could potentially advise me on how to configure my inverter to run in bypass mode when there is utility power and only enter line mode when the utility power is not available? I basically only want the inverter to only be active during load shedding times. At the moment it runs all the time except when the load is too high, then it goes into bypass mode (as intended). The moment the load reduces, the inverter is active again. Using a clamp meter, I can see that there is current moving between the inverter and batteries even when the utility power is on. I don't want the inverter and batteries to work all the time. It seems more feasible for longevity to use the kit only when there is no utility power. No solar just yet. That's next, as funds allow. Thanks

Hi Guys. Given the two different RS485 pin-outs that seem to work per this thread, has someone perhaps compared functionality for potential differences, perhaps in commands or feature sets supported or does it not matter which pin-out is used between these two?
