Thanks everybody for your kind and useful responses.
The project involves two solar installations which are close to each
other and as generators they are separate. However it appears that for
monitoring purposes, (equipment manufactures advice) it would be better
to have the two systems integrated hence the last minute call for a
wireless link. It could have been incorporated into the system whilst it
was being built but that didn't happen. I have passed on the excellent
suggestion of a fibre link.
In the distant past I did install a couple of wireless bridges across
farmyards using normal domestic equipment costing in the order of £50
plus antennae and they seemed to be OK. However for this job, I thought
that I would try and find something industrial standard . It seems that
the sort of equipment found on Amazon although cheap appears to be
adequate although I think a well made, rugged system is required here.
A few years a go was lucky enough to be involved in a project in Africa
and we were advised to use "Teltonika" equipment for comms and it looked
the part, aluminium case, rail mounted. What I meant by robust. It has
been working for 3 years without failing.
My friend has ordered something Chinese from Amazon just to get going
but chances are he will come back to it later.
Thanks for your help.

This has to be very robust.
Hi,
When you say "This has to be very robust.", what do you mean?
Also, how future proof do you need it? Bandwidth?
What is it linking? Two buildings the person owns? Is the field owned
by them, or someone else.
Why not get broadband to each building, and then VPN across the
internet between them?
I would be tempted to dig a trench and put some single mode fibre down
it. It is a bit of effort, but 180M is not far to dig.
It will also be future proof as you can put any bandwidth you please
down the fibre cable.
If you need robust, do you need dual links? In case one fails?
Kind Regards
James
