I have a Royobi 2kva (1750w) inverter generator and a 5kva inverter with a 5.12kwh Dyness battery(trolley inverter) I have changed the current and start/end settings accordingly (soc) but when I plug the unit into the generator it sounds as if the generator is taking heavy strain, and it sounds as if the inverter is switching on and off continuesly. Do I perhaps need to change this setting as well? Or is the power generated by the generator not sufficient? Only the inverter is connected to the generator.

I think you should try dropping the Max generator input and dropping the generator charge battery.

Im pretty sure all inverter generators have AVR so its probably just trying to pull too much power from the genny.

If you drop them until it starts working then at least you are getting some charge into the batteries, in an extended outage that is very important.

Set genny stop voltage at 54V from 48V. Also set the genny charge Watts to 300W with no loads on the inverter. Then try and see if you can at least keep the inverter happy and the genny not taking strain. Then you can gradually increase the charge Watts. 

Good luck and if it does not work try running without inverter and run bare essentials while you have the long power outage. 

Guys let's try and help Anton while they are heading to 24hrs without power.

I figured out how to charge my battery, when using the generator input, the important figure is the Generator Charge Start Battery SOC(%), set this to 90%, otherwise the charge current is very small (+-50W). Make sure your Max. Generator Input power(W) is correct for your Gen (mine is 3800W). I set the Generator Charge Battery Current(A) to 12A on mine. This then runs the Load and charges the battery at 600W. The Grid is down in this scenario.
