There has always been much discussion on grounding small systems. For homes on the prairie and in areas with frequent lightning
its good to have a lightning arrester, but they are expensive and not everyone has them. Especially with small 1-2 panel systems.And there is no guarantee of an arrester saving all your gear.
In a home with good wiring /quality appliances etc there is little chance of the ground system actually being in use. But there might be more chance of lightning
hitting a few hundred ft away( monthly) and going up the ground wire towards the controller etc.In a situation like that someone might decide that its better to not connect the ground system.What do you think of that??
