inverter>network cable>router>internet>router>pc - HOW?

[ggs]

the short is above, slightly longer it goes like this:
i have a king axpert inverter with a RS-232 communication port with a network cable from there to a router which i can access,
on another location i have a router connected to a pc [the one i'm typing on ]
on this pc i have the viewpower software used to interrogate the inverter.
there is also a pc connected directly to the 1st router which i can access through anydesk; this pc also has the viewpower software installed.
HOW do i access the inverter via its software on the far pc, the one i'm at?
thanks in advance
gabriel

I'd go for a VPN between the two networks.

tx @Messugga - indeed, we have two networks, the inverter-router-pc one at locale a and the router-pc at locale b, that is here where i am. how would i set up a vpn between those?
i can connect with the a network via anydesk/teamviewer...

@Steamy Tom - that most probably is so but if i can get that running i'm sure i can move on to something else... one of the reasons i am at a loss is the chinglese 'instructions'
