Solar energy is one of the safest and most reliable ways to power homes and businesses, but not all solar systems are created equal. When it comes to safety, SolarEdge’s optimised systems stand out with advanced technology designed to prevent electrical hazards, reduce fire risks, and improve system performance. Here’s why SolarEdge is the safest choice for your solar installation.
One of the standout safety features of SolarEdge is SafeDC™. This technology automatically reduces DC voltage to a safe level (below 1V per panel) when the inverter is turned off or in the event of an emergency. Traditional string inverter systems can leave high-voltage DC running through the cables even when the system is not actively producing power, increasing the risk of electrical shocks or fire hazards.
SolarEdge inverters are equipped with built-in arc fault detection and interruption (AFCI) technology. This system continuously monitors the solar array for any electrical arcs, which can occur due to damaged wires or poor connections. If an arc fault is detected, the system shuts down automatically, reducing the risk of fire.
SolarEdge’s optimised systems allow for module-level monitoring, which means that each panel’s performance can be tracked individually. This not only improves energy output but also enhances safety by quickly identifying any malfunctioning panels. In case of an emergency, SolarEdge’s rapid shutdown capability ensures that first responders can safely access the site without high-voltage risks.
Traditional string inverter systems connect multiple solar panels in a series, meaning the voltage of the entire system is cumulative, often reaching up to 600-1000V DC. If a fault occurs, shutting down the inverter does not immediately reduce this high voltage, leaving cables and panels live and potentially dangerous.
SolarEdge’s DC-optimised technology eliminates this risk by controlling voltage at the module level. When an inverter is turned off, the voltage of each panel is automatically reduced to a safe level, minimising potential hazards for installers, homeowners, and emergency responders.
SolarEdge systems meet and exceed global safety regulations, including:
-
AS/NZS 5033: Australian standard for PV installation safety, ensuring rapid shutdown compliance.
- NEC 690.12: U.S. National Electrical Code requiring module-level rapid shutdown.
- IEC 62109: International safety standards for PV inverters.
By choosing a SolarEdge system, homeowners and businesses can be assured that their solar installation meets the highest safety standards worldwide.
When it comes to solar energy, safety should never be an afterthought. SolarEdge’s advanced safety features—including SafeDC™, arc fault detection, and module-level monitoring—make it the best choice for homes and businesses looking for reliable, risk-free solar power. Whether you're installing a new system or upgrading an existing one, SolarEdge ensures maximum protection, greater efficiency, and long-term peace of mind.
