Simplest way to switch inverter on vi 4g/cellular network? off grid cabin

Hey all, I have the victron inverter (MultiPlus-II 24/3000/70-50 2x120V (UL)). I want to switch it on via 4g so I can switch on the inverter from home.. I live 2 hours away and it is completely off grid.

I believe I need to get the Cerbo GX and that Victron 4g modem? that will run me about $400 so I am hooping there is maybe another way that won’t be as steep? I really only care about switching it on

Victron also has the globalink 520 but it is not compatible with the multiplus II.

The multiplus has a connection terminal where you can switch the inverter off and on/charge only. You can use this with any third party solution.
