A negative grounded PV system is a solar electric system where the negative terminal of the PV solar power array is connected to the ground. This connection is made through conductive materials like a fuse, circuit breaker, resistance device, non-isolated grounded AC circuit, or an electronic means within an inverter or charge controller.
Negative grounding in solar inverters improves the overall performance of the solar power system by reducing electrical noise and interference, ensuring the smooth functioning of the inverter and the solar system. Grounded Vs. Ungrounded PV Systems: Which to Choose and When?
DC circuit grounding: Depending on the system design and local codes, one conductor of the DC circuit (usually negative) may need to be grounded. Frame grounding: All metal frames of the solar panels are interconnected and bonded to the main earthing system.
Solar PV systems are still permitted to be grounded, per 690.41 (A) (1) and (5), and, for those PV systems that are, the dc grounded conductor is directly coupled (or coupled through electronic circuitry) to the ac grounded conductor, which is then brought to ground potential by being terminated to the neutral bus bar at the main service panel.
While both grounded and ungrounded PV systems can offer equal safety levels, grounded systems provide better ground-fault protection and are less susceptible to nuisance trips. Also Read: 3 Leading Types Of Solar PV System Grounded Vs. Ungrounded PV Systems Price
However, grounded systems, common in North America, offer better fault protection but may have more complex operations. On the other hand. ungrounded systems, prevalent in Europe and Asia, rely on capacitance and might be less expensive due to no grounded conductor requirement.
