Power for modems

[andypipe]

What would be the effects of installing a single socket fed from the AC isolator for the invertor, for a modem, where the invertor is mounted in the loft?

You may get pigeons roosting on it.

 

[moggy1968]

wouldn't be a problem I think as you could argue it is part of the system, but why not use a socket taken off the lighting circuit as is often used for aerial boosters, or even better off the ring if your really lucky and the wirings in the loft?

Section 2.3.1 of DTI guide says
'An inverter supplied from a PV array must preferably be installed in a dedicated circuit in which:
no current using equipment is connected....'

 

[moggy1968]

you can't argue it's part of the inverter installation then?

 

[Markc]

I would prefer to see it taken off the lighting circuit or socket circuit if possible. It could be argued that if you have this option then you should of used it. The DTI guide is good but vague "preferably" being the key word there.

You could argue 712.411.3.2.1.1 is also relevant as if there is any current using equipment on a solar circuit then the solar PV is not connected to the supply side of the mcb providing protection to current using equipment.

Fair point also.

I would have liked to have used a non-standard e.g. 2A socket for this (as recommended for table lamps), but since my wireless repeater came with a combined power-supply/plug there was no option but to fit a 13A socket.

So I think the spirit if not the letter of Part P was met by using a spur box off the lighting circuit fitted with a 3A fuse, and labelling both spur box and socket 'wireless repeater only, fused at 3A'.

It appears that most of the posters to this thread are answering questions that have not been asked?
To my mind, it would be better if the OP explained exactly what they are proposing before anyone wastes time answering hypothetical questions that may or may not be relevant.
For all we know, the inverter is being used to run a 3phase Radon fan supplied from the grid and there is no PV involved.

Well I guess if you can run a 3 phase radon fan from a modem then that is what he might be doing...
OR
maybe he wants to connect a modem close to the inverter so he can collect data for monitoring...

Got it in one

pedantry rules!
As we are on a PV forum then I think it fair to assume that this is a PV related issue.
Of course, assumptions can dangerous!

Notwithstanding spinlondon's facetious and unhelpful comments it would be good to know if the OP's original query has now been answered, and if not what further help is needed!

I never suggested that the OP wanted to run a modem off of a fan.
The OP wants to run it from an isolator for an inverter.
Does the inverter have two a.c. isolators, one from the grid side to power the inverter and another for the a.c. output?
What sort of effects does the OP envision occuring?
Perthaps if the OP actually asked a sensible question, they'd get a sensible answer.
