Afternoon  On The Solar system I got 5.12kw  lithium battery during load shedding  the  battery is  80% charged  but when we use the microwave it trip at the time only fridge, freezer and and a could lights is there a setting that I can do ?

What is the size of your inverter?

I would guess that the current limit on your inverter is being exceeded.

EG my inverter has a 4.6kw limit, and allows a 50% overdraw (6.9kw) for 10 seconds. So if we turn on the right (wrong!) combination of devices then that limit gets exceeded and the inverter trips.

And this is a hard limit, not anything that you can configure. 

Check to see what your microwave draws and if it is really the only thing running. Almost certainly there is something else running, maybe not big loads, but they add up.

What battery are you using? Is it 1C or 0.5C?

sounds like 0.5c battery - ideally try not to use microwave / kettle or other high draw items during LS with only 1 battery. If you get a 2nd battery you'd be safer

I think he is exceeding the load limit on the inverter.

Very easy to exceed a 0.5C(2560W) limit of the battery as well if fridge and a freezer is already running on 48V system. Make sure what the 230V input to Microwave is and not the normal microwave output.
