I have a wooden shed at the end of the garden not connected to the house in any way. I have a 330w panel on a wooden stand, two batteries, a 100/30 smart controller, a Victron 375w inverter, two low wattage led lights. The controller and inverter are grounded using an 8' copper stake. The batteries aren't grounded. It is a 12v system. Everything is fused correctly. Should I ground my panel as well to it's own dedicated rod or not ground it at all. The controller manual says something about it (the controller) is not to be used with arrays that are grounded. It wasn't clear. I am in the UK.
