SPD – SOLAROM

These specialized AC Surge Protective Devices (SPDs) deliver critical, industrial-grade defense against catastrophic voltage spikes, grid transients, and lightning surges occurring on the alternating current side of photovoltaic systems. Installed as a safety gate between the solar inverter's output and the main property distribution panel, these robust surge arrestors instantly clamp dangerous transient voltages. This nanosecond-fast redirection routes destructive electrical energy safely away into the earth channel, keeping your sensitive household appliances and expensive inverter circuits fully intact. Engineered with convenience and system uptime in mind, these AC SPDs feature a compact, 35mm DIN-rail mountable layout with user-friendly plug-in cartridges that permit rapid, tool-free replacement without disturbing primary system wiring. Complete with clear, color-coded mechanical fault flags for effortless health monitoring and integrated thermal disconnectors to eliminate fire risks, they provide an indispensable layer of code-compliant safety for any modern renewable energy electrical infrastructure.

The Suntree 40kA 2P DC Surge Protective Device (SPD) delivers industrial-grade defense against catastrophic voltage spikes, lightning surges, and transient overvoltages within photovoltaic power systems. Featuring a heavy-duty two-pole (2P) design, this Type 2 solar surge arrestor concurrently isolates and shields both the positive and negative DC lines running from your solar array. Armed with premium high-capacity metal oxide varistors, it clamps massive electrical surges within nanoseconds, safeguarding expensive string inverters, charge controllers, and downstream components from fatal circuit damage. Engineered with system longevity and ease of maintenance in mind, the Suntree DC SPD utilizes a modular plug-in design that permits rapid, tool-free replacement of depleted cartridges without disconnecting the main system wiring. The unit integrates seamlessly onto standard 35mm DIN rails inside combiner boxes or distribution panels and features a highly visible color-coded fault indicator window (green for healthy, red for replace). Equipped with an internal thermal disconnector to prevent arc-induced fire hazards, it provides essential, code-compliant peace of mind for any renewable energy infrastructure.
