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

I'm not a King owner, but I think what you need is setting 23 to ByE (Bypass enable), and setting 10 (operation logic) to ECO.

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.

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.

Hi All

I have a similar issue, but with a 3 phase installation.

I have tried the steps suggested above, but not having any luck.

Can anyone give some helpful advice?

Thanks

Just a note... It looks like you don't have any PV input in which case the above config is great and the most efficient (unless you have very sensitive loads). If you do connect PV you are going to want to run it in line mode to make the best of power coming in from your PV, otherwise once the batteries are charged PV power is wasted.

Same problem here. Done that but fans still on. Must I restart device, wait some time?
