Solar PV Grid Connect earthing requirements are now mandatory for transformerless systems and will soon be required on all tranformer based systems as well.  The minimum standard is a 4mm earth taken from the main earth bar to the solar array.

Earth bonding must be mechanically and electrically sound for the life of the system.  Screws and bits of wire are NOT acceptable and will NOT ensure a solid earth bond.  In fact they will quite often cause a reaction of metals resulting in damage to the aluminium mounting system.

Ecoelectric use a stainless steel lug connection that is proprietry to our rail kit.  The stainless steel ensures minimal reactions and an electrically tight connection for years to come.  Our panels are bonded with stainless steel earthing washers enabling 4 points of contact in 2 locations on every panel.  These connections are guarenteed to stay electrically continous in even the harshest conditions.
