Surge Protection

Surge Protection Devices

Defend your solar, battery, and electrical systems from voltage spikes with surge protection devices (SPDs) from PES Supply. Lightning, grid switching, and load changes can send damaging surges through your system. SPDs divert this excess voltage to ground, protecting inverters, batteries, and sensitive electronics. Shop brands including Midnite Solar, Schneider Electric, Eaton, OutBack Power, and more.

Surge Protection Options

• DC surge protectors for solar array and battery sides
• AC surge protectors for inverter output and panel mains
• Type 1 and Type 2 SPDs for different installation points
• Replaceable modules with visual fault indicators
• Combiner box integrated surge protection

Surge protection is a low-cost insurance policy for expensive equipment. A single lightning strike nearby can destroy an inverter costing thousands. Type 2 SPDs protect against indirect surges, while Type 1 devices handle direct strikes on service entrances. We recommend protection on both DC and AC sides of every system.
