Does it matter where the Inverter is to be sited?

Does it matter more for the Inverter to be sited nearer the solar panels having a shorter D.C. run? OR Is it better for the Inverter to be sited nearer the consumer unit having a shorter A.C. run?

I think most installers try to keep the DC run as short as possible, but there is nothing wrong in a long DC run if you have no choice. If the DC run is that long they should do the calculations and use the correct size DC cable.

To minimise the risk of faults, PV D.C. cable runs should be kept as short as practicable.”

is it ok in loft/roof space or is this likely to be too hot?

The loft space is actually the most popular place to install the inverted box. This has the benefit of a short DC cable run and minimum installation disruption within the living spaces of the property.
I’ve never heard of temperature being a factor for the inverter, but cooler panels do work more efficiently (contrary to popular belief).
