Spd solar panels

[Lt1990]

Hi got a 8 panel solar system on bungalow, changing the board to 18th edition spd board
Solar feed is chased into wall so will this need a type B rcbo or can you get away with the type A rcbo.
Also reading multiple different things about spds do I need one installing at the solar inverter aswell as the the main one in consumer unit

Are you an electrician? This seems like a very odd question to ask.

I am an electrician with no solar experience, just been on a solar course on how to complete the testing side of solar for work which only lightly touched on spds and rcds for solar

Then you would be familiar with the difference between Type A and B RCD protection and how, if at all, selection would be impacted by burial of cables in a wall.

Yea I do
It was more the spd at solar end I was more enquiring about than rcbo just wanted to confirm it for my own sake as I was questioning myself over it as the understanding I have is type B is just needed for solar anyways
