DEHNguard MP YPV
Defend PV systems from damaging voltage surges
The DEHNguard MP YPV type 2 DC surge arrester defends against unpredictable electrical surges that threaten photovoltaic systems, shielding PV assets from damaging voltage spikes that could lead to downtime and costly repairs.
With the DEHNguard MP YPV, your solar infrastructure stays protected and productive for continuous, reliable energy output.
The hidden risk to PV systems—and how to stop it
Photovoltaic systems aren’t just a means of reducing utility bills—they’re a long-term investment in cleaner energy, energy independence, and increased property value. However, these systems are at risk of severe damage from overvoltage caused by lightning strikes, grid surges, and other transient voltage events, such as electrical anomalies from switching operations or insulation faults.
When a transient surge occurs, it can travel through cables and connections, causing serious and expensive damage to the sensitive components throughout the solar generator circuit. Without a surge protective device to protect PV systems, a single transient voltage spike can disrupt operation, bringing power generation to a standstill.
The DEHNguard MP YPV surge protection solution protects against these threats by absorbing and diverting transient surges. With the DEHNguard MP YPV, your PV system operates at peak efficiency—without the looming risk of unexpected surges cutting into equipment productivity.
DEHNguard MP YPV: Powerful surge protection for PV systems
The DEHNguard MP YPV is a quick-connection surge protection unit for photovoltaic systems in residential buildings, commercial buildings, and solar farms. This type 2 DC surge arrester absorbs and redirects transient surges that would otherwise reach vital system components. By neutralizing dangerous voltage spikes, it prevents critical parts, like inverters, DC battery storage systems, and power cables, from damage and outages.
Features of the DEHNguard MP YPV include:
- Practical push-in double terminal design: Quick connection technology saves installation time without the need to assemble plug-in protection modules.
- Visible clamping: This enables easy visual inspection to confirm secure connections and prevent installation errors.
- Compact, modular build: Feed-through wiring eliminates the need for additional push-in connection terminal units.
- Integrated remote signaling contact: Push-in terminal protection for easy remote monitoring.
- PE connection: Up to 10 mm² (flexible, rigid, fine-stranded).
- Compliance: For use with PV systems per IEC 60364-7-712.
With robust protection features, the DEHNguard MP YPV is ready to defend your PV system from damaging surges and keep your solar power systems safe. Available in two variants to meet diverse installation needs, DEHNguard MP YPV 1200 FM and DEHNguard MP YPV 1500 FM, the DEHNguard MP YPV provides versatile, reliable protection for any PV setup.
