PVA Series
Introducing:
Solar installations represent significant investments that need protection from electrical surges. While AC surge protection has been standard for decades, DC power systems face unique challenges that require specialized solutions.
The PVA Series addresses the growing need for reliable DC surge protection in solar installations, PLCs, SCADA systems, and industrial control applications.

Install with Confidence
DIN-rail mounting and comprehensive support ensure successful installation and long-term system reliability.
Built for Real-World Solar Environments
The PVA Series combines maximum surge current ratings up to 50 kA with DIN-rail mounting for residential and commercial installations. These devices feature window fault indicators that show operational status at a glance and individual module replacement that reduces maintenance costs. Available in multiple voltage ranges from 48V to 1500V DC, they adapt to various solar system configurations while meeting UL 1449 standards for DC surge protection devices.
Weather-Resistant Design
Engineered enclosures withstand random weather systems, extreme weather, and daily exposure. Protection that works when solar systems actually operate.
Visual Status Monitoring
Window fault indicators provide clear visual confirmation - red indicates service needed, green confirms operational status.
Scalable Protection
Same protection technology scales from single residential strings to multi-megawatt installations. Consistent performance at any project size.
Reduced Maintenance Costs
Replace individual protection elements instead of entire systems, significantly reducing long-term maintenance expenses.
Peak Season Reliability
When solar generation peaks, downtime hurts the most. Nanosecond response and 50kA capacity prevent interruptions when systems are most valuable.
Minimized Downtime
System maintains partial protection during individual module service, reducing vulnerability periods.
Why Solar Needs Different Protection
Solar panels and DC power systems can't rely on traditional AC surge protectors. Lightning strikes and utility switching create different surge patterns in DC systems, and the continuous DC voltage means surges don't naturally extinguish like they do in AC systems. Without proper DC surge protection, expensive equipment, monitoring systems, and even solar panels themselves become vulnerable to damage that standard homeowner's insurance often won't cover.
Whether protecting a residential rooftop installation or a multi-megawatt solar farm, DC surge protection scales with the application. Small residential systems need protection for their inverters and monitoring equipment, while commercial installations require protection for multiple string configurations and complex power management systems. Utility-scale projects demand robust protection that can handle the high voltages and currents found in large solar arrays while maintaining system uptime.
From Rooftops to Solar Farms
Industrial Controls Demand DC Protection
PLCs, SCADA systems, and variable frequency drives rely on DC power circuits that face the same surge vulnerabilities as solar installations. Control panels often house 24V logic circuits alongside higher-voltage DC power systems, creating multiple protection points within a single enclosure. Manufacturing downtime from surge-damaged controllers can cost thousands per hour, while water treatment facilities and automated systems require continuous operation. DIN-rail mounting enables integrated protection for DC power, AC circuits, and communication lines in the same panel space where industrial equipment operates.

DC Power
Battery back-ups store extra power obtained during the day for use at night or when there is insufficient sunlight. While the batteries themselves don't require surge protection, the DC wiring connections may benefit from surge protection devices.

AC Power*
Generators provide final backup power if there's no sun for several days or insufficient stored energy for evenings. In modern off-grid systems, generators connect to the inverter (not main panel) for automatic start/stop operation, ensuring off-grid homes never lose power.
