I am just getting quotes for a domestic, grid connected, solar installation.
Being on the side of a hill, my house has a slightly unusual layout, with a patio on the top level. I would like to position the inverter there where it will be protected from the weather. The meter box is on the lowest level.
The company that I have just had a quote from would put the inverter next to the meter box where it would be exposed to sun and rain. They claim that the system would not run at peak efficiency due to losses if the inverter is more thatn 15m from the meter box (on the patio it would probably be about a 25m run). They held to this story even when I suggested that they run heavier cable (which I would be prepared to pay for).
The bottom line is that they will only install the inverter on the patio if I sign a waiver acknowledging that this is against their recommendation.
Can anyone suggest why there would be any problem with this?
