Technical FAQs 4
What is effective grounding in photovoltaic (PV) systems?
Effective grounding in photovoltaic (PV) systems is the creation of a low-impedance reference to ground at the AC side of the inverter—or group of inverters—that is designed to be compatible with the distribution network’s requirements and existing grounding scheme.
How to ground a PV inverter?
In general, effective grounding can be achieved with a grounding transformer as shown in Figure 1 (a). If the PV inverter has an internal transformer with the grounded wye to delta configuration, a grounding reactor can be used instead by accessing the neutral point of the inverter transformer.
What is grounding a solar inverter?
Grounding a solar inverter is referred to as connecting the metal casing of the inverter to the earth, creating a path for extra electrical current to be safely discharged. This concept is an important safety measure that can help you prevent electrical shock and reduce the risk of fire in the event of a fault or surge in the system.
What is the effective grounding design tool for Solectria inverters?
Solectria provides a spreadsheet ‘Effective Grounding Design Tool for Solectria Inverters’, which conveniently calculates parameters involved in effective grounding projects using Solectria inverters. A sample case study using this spreadsheet is included as a reference which is similar to the example provided in IEEEE P1547.8.
