Surge Protection Devices

Advanced surge protection systems that prevent costly inverter damage from grid surges, lightning strikes, and electrical faults. Essential protection for your FIT investment.

Key Features

  • Type 2 SPD protection for comprehensive coverage

  • Lightning surge immunity up to 40kA

  • Automatic fault disconnection circuitry

  • Visual status indicators for easy monitoring

  • Thermal overload protection

  • Modular design for easy replacement

Technical Specifications

Protection Type:

Type 2 SPD

Maximum Discharge:

40kA (8/20μs)

Voltage Rating:

230/400V AC

Response Time:

< 25ns

Standards:

IEC 61643-11

The Cost of No Protection

Without proper surge protection, a single lightning strike or grid surge can:

  • Destroy your inverter (£1,000-£3,000+ replacement)

  • Cause weeks of FIT income loss during repairs

  • Void equipment warranties

  • Damage sensitive monitoring equipment

SPD protection typically costs 10% of inverter replacement

—it's essential insurance.
