non combustable board

[Markc]

You can get flame retardant sprays and coatings that treat wood and offer the required protection. It's the same as what is used on meter boards.

Not sure if this is a way round the problem. Yet again it's up to us installers to solve the issue.

May be develop some thermolite board!

On our installs we've always fixed to brick/stone walls , I have to say I don't think its a good idea to fix to ply/wood etc mainly because of the weight of some of these inverters, and with the heat from the inverter I can't help thinking the ply/wood will deteriorate over time possibly even leading to the areas around the fixings becoming weak over time.
we mainly use SMA and after reading the pdf on mounting on wood decided we would follow that advice, and if necessary fix to unistrut, or concrete fibre board

This pdf does say you can mount to wood as long as there is an air gap and the inverter is spaced via washers at fixing points , however before anyone does this read the datasheet and decide for yourself
