A pv system’s steel, noncurrent-carrying additives need to be bonded collectively and then bonded to earth thru using an system-grounding conductor (egc). Article 250 establishes more than one methods in which this bond can be installed. For pv systems, the maximum not unusual method is to apply a conductor to bond the materials together, specially from the pv array.?.
For pv systems that use grounded contemporary-wearing conductors, i.E., Systems the use of transformer-based totally inverters, phase 690.Forty seven is the number one reference for the grounding electrode system. In grounded systems, a connection must be made between the dc circuit grounding point and earth, as required in 690.Forty one and 690.Forty two. This required connection consists of the grounding electrode (ge) and the grounding electrode conductors (gecs). It's miles well worth noting, irrespective of the inverter’s use of a transformer, that the egc necessities mentioned constantly practice. It is also very essential to read the set up commands covered with all inverters to ensure all of the grounding instructions particular to that inverter are being observed.
All three of 690.Forty seven(c)’s subsections require that the dc grounding machine be linked to the ac gadget’s grounding electrode. For grid-direct pv systems, this is normally the prevailing grounding electrode—a floor rod, water pipe, concrete-encased electrode, and many others. A new dc grounding gadget connection to earth may be completed by:.
Every of those provisions has its own particular set of guidelines to comply with. Grounding and bonding is constantly a complex case. Future articles will discover these 690.47 requirements in greater element to assist decipher the grounding electrode device necessities.
