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
