The Suntree Surge Protector (OVR) – 2 Poles is a compact, high-performance device designed to protect DC electrical circuits in solar photovoltaic (PV) systems from overvoltage events caused by lightning, switching surges, or grid faults. It safely diverts excess voltage to ground, shielding inverters, charge controllers, and other sensitive equipment from damage.
Designed for 2-pole DC applications, this surge protective device (SPD) is ideal for solar string configurations and DC combiner boxes. Its modular design allows for quick replacement without rewiring, while its compact profile ensures it fits easily into control panels or distribution boxes.

Residential, commercial, and industrial solar systems
Mount the SPD onto a 35mm DIN rail inside the enclosure.
Connect the positive and negative DC input lines to the SPD terminals.
Ensure a secure ground connection from the SPD to the system’s grounding network.
Power on the system and verify the green window indicator is visible.
Inspect periodically and replace if the indicator turns red.
