Without proper grounding, these risks can lead to system damage, fire hazards, and operational downtime. Bluesun Solar emphasizes professional grounding designs to protect systems and ensure long-term reliability.
What is electrical & PV grounding?
Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.
What is a grounded PV system?
A PV system is defined as a grounded system when one of the DC conductors (either positive or negative) is connected to the grounding system, which in turn is connected to the earth. The conductor that is grounded usually depends on the PV module technology.
Do I need a grounding electrode for a PV array?
While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.
