Surge Protection PV
PV Surge Protection – dependable DC-side safeguarding
This fuse type indicates surge protective devices (SPDs) designed for photovoltaic systems. They clamp transient overvoltages caused by lightning-induced surges or switching events and safely divert energy to earth, protecting modules, inverters and communication lines.
Typical installation points
- String and combiner boxes (DC side)
- Array/sub-field level in large plants
- Close to the inverter or DC busbars
Key features
- PV SPD classes Type 1, Type 2 or Type 1+2
- High DC ratings (e.g. 600–1500 V DC)
- Pole configurations to match system design (1 to 3 poles)
- Pluggable modules, visual/electrical status indication
- Compliant with relevant PV SPD standards
Benefits
- Reduces downtime and repair costs
- Improves system availability and yield
- Supports compliance with design and installation rules
Note: Choose SPD class (Type 1/2/1+2), DC voltage rating and location according to lightning protection concept, string voltage and cabling.
