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



 
 

Hallo @Nellis.Theron
It might be that the voltage detected from the inverter is lower than 47.5V while the kettle is turned on.
Are you making use of the inverter settings (29=47.5V) as your Back to grid?
Are you making use of the inverter to detect when to switch from solar to grid or are you using ICC battery monitoring software?
If you only use the inverter to detect the voltages to switch you may have to drop the "Back to Grid voltage" lower.
Have a look at the Voltage trend to see if it is the case.

See FAQ question 2. You need setting 49 at 46.0 V or less. Or use the LFP flavour of the patched firmware. If you can use the latter, it will have the advantage of load compensation, which further reduces nuisance switching to line mode. Also, if it does, it will be for 2 minutes instead of 10 minutes. See Can I update my firmware, and if so to what?

@Nellis.Theron  I run 1 Axpert 5kw with 3*3000 Pylontech batteries . Making use of ICC with the Pylontech cable they make . Centurion solar did the programming of the Pi . Setting no 13 was set at 50 by them . I run offgrid and had no problems so far . I can be wrong but 51 volt for a 15 cell Lithuim battery is bit high to change back to grid . a 2000 watt load will pul the voltage below 51 volt if there is no or low Solar input and the inverter will switched back to the grid . Even setting 29 at 47.5 is high . The battery low warning will start at 49.5 . which is problematic . The battery voltage will have to rise to 51.5 v before the alarm resets . 29 was also set lower by ICC installers .
