As I have started of with 2 x 5 kW inverters, my solar panels provide power through these two panels and the 3 rd inverter gets power from the grid and battery.
My problem now is that in the case I draw about 9 kW from the system and the battery voltage came down to 47 V the whole system trips out (goes dead) and have to reboot.
At night time with less of a load on the system and the battery comes down to 47 V, the system elegantly switches over to the grid until the battery reaches "back to battery" voltage.
My question is why the system elegantly switches to the grid when the load is low and trips out (without switching to the grid) when the system is under load?
I have added the third inverter to overcome this challenge, but sadly it made no difference.

I have a solar system consisting of:
1. 18 x 330 W solar panels
2. 3 x 5 kW Axpert inverters
3. ! x 10 kW Dyness Li-on battery
As I have started of with 2 x 5 kW inverters, my solar panels provide power through these two panels and the 3 rd inverter gets power from the grid and battery.
My problem now is that in the case I draw about 9 kW from the system and the battery voltage came down to 47 V the whole system trips out (goes dead) and have to reboot.
