Before you connect a solar inverter, you need different electrical protections. These are overcurrent protection, surge protection, ground fault and arc fault protection, proper grounding, isolation, and following safety rules. Solar systems can make enough voltage to shock or electrocute someone. . Anti‑islanding protection detects that condition and stops exporting power quickly. Grid codes exist to keep people safe and the system stable as solar and wind grow. ABB's products include string boxes, miniature circuit breakers, switch-disconnectors, residual current-operated circuit breakers, interface relays, energy meters, fuse disconnecting switches and fuses, surge arresters, consumer. . All DC conductors of renewable energy systems, both grounded and ungrounded, installed inside a building or structure will still require metallic raceways cables and enclosures, based on Rule 64-062.
