Suntree 2P DC Surge Protector 500VDC 40KA — Ultimate Protection for Solar PV Systems
Safeguard your photovoltaic installation from damaging voltage spikes with the Suntree 2P Surge Protective Device (SPD), engineered for high-performance DC surge protection in solar energy systems. Rated at 500V DC with an impressive 40KA nominal discharge current, this 2-pole surge arrester delivers industrial-grade defense against lightning strikes, switching surges, and transient overvoltages.
Key Features
- Voltage Rating: 500V DC — ideal for residential and commercial solar PV arrays
- Maximum Discharge Current (Imax): 40KA for robust protection against high-energy surges
- 2-Pole (2P) Design: Simultaneous protection of both positive and negative DC lines
- Type 2 SPD Compliance: Meets IEC 61643-11 standards for secondary surge protection
- DIN Rail Mounting: Quick, tool-friendly installation on standard 35mm DIN rails
- Thermal Disconnect: Built-in protection prevents overheating and fire risk
- LED Status Indicator: Instant visual confirmation of operational or fault status
- Compact Form Factor: Space-saving design for use in solar combiner boxes and DC distribution boards
Why Choose the Suntree 2P 500VDC 40KA SPD?
Solar panels and inverters represent a significant investment — and they’re highly vulnerable to transient surges caused by lightning, grid switching, and inductive load changes. The Suntree 2P DC Surge Protector acts as the first line of defense between the elements and your system’s critical components.
With a maximum continuous operating voltage (Uc) of 500VDC, this SPD is precisely matched for standard 48V battery banks, on-grid solar strings, and off-grid PV configurations. The 40KA discharge capacity ensures even major surge events are safely diverted to ground before they can reach your inverter, charge controller, or monitoring equipment.
Applications
- Rooftop and ground-mounted solar PV systems
- Off-grid and hybrid solar installations
- DC combiner boxes and junction boxes
