The best is to contect the battery provider. That's how I managed to get my settings.

I'm also experiencing similar problems with my Mercer 5kw inverter. My inverter will during the day turn the PV panels power off even if the batteries are not fully charge. Regards Willie

Thanks for the reply. Lots of fun Let me know if I can assist

haha, thanks for the comment. Just love development. Must say I was very disipointed with the Axpert inverter (it's a device from the 80s!) Using a Raspberrypi 4 with 5inch touch screen (abount R 2300 with the box and all parts ), Grafana for graphs (it's so powerful !) and my own Python script that manage the Axpert Inverter. Next is the write an Android and ios app or maybe intergrate.

After my installation I started playing with my new "TOY" but quickly realize that it's not going to perform to the levels I wanted to. So like any software developer I started developing my own software. I wanted to achive the following goals: - Generated max power, use the power as long as posisble, switch over to grid when needed - Automaticlly change the power management for load-shedding - Protect my batteries against high power usage by switching over to grid when power usage exceed X for a few minutes and back when usage recovered - Only switch to Solar when Batteries is over X voltage and Solar is over X Watt (provide to levels) - Switch over to Grid in the afternoon when Solar is under X level or Time. - Identify Low average power generation (Clouds, Rain) - For Load-Shedding - Move from Solar Charge only to Solar/Grid when batteries are very low or for Load-shedding I also wanted the system to look "Cool" and I wanted to make it accesable from a browser. Bought a Raspberrypi and screen... Here is the results...so much fun... still learning

Use the USB port. You can also download sample Python scripts to read the port (USB-Serial)
