Enable Island mode on Growatt MIN TL XH without backup box

Hi there!
There is a way to enable island mode (or "pure off-grid mode") on a MIN TL-XH without Backup Box? Maybe using Enable+/Enable- pins of SYS COM port as is possibile to do on Huawei SUN2000 (as shown here)??

thanks

nobody??

There's a modbus register, 230 in the holding register, "islandDisable" that can be written. Not sure what it does, apparently 1 is disable, and the default value is 0 which I'd interpret as island-mode default enabled...which isn't the case.
Might be unrelated/useless though, but it's the closest I can get.

Hi, in advanced setting, enable backup-box and enable manual off grid, disconnect from the grid and wait a minute.
