Safe

Improving safety in solar systems depends on eliminating the risks associated with high-voltage DC wiring.

Central inverter-based solar systems have a wide distribution of high-voltage DC wiring. If damaged, DC wires can generate sustained electrical arcs, reaching temperatures of more than 6000 degrees F. This increases the risk of fire and electrocution for systems owners, installers and fire fighters.

In contrast, Enphase Microinverters eliminate all high-voltage DC wiring from the solar array and are connected together using standard AC wiring. This dramatically reduce the risks of fire and injury.

“As both a solar installer and firefighter, fire safety around PV systems is of particular interest to me. The changes to the National Electric Code to address DC arc faults are an important step for those of us who deal with fires regularly.”
