Questions about this product
- Can I use this surge protector on my home solar panel system?
- Yes, this DC surge protector is specifically designed for solar arrays, inverters, and charge controllers. Match your system's voltage to the correct model rating between 500V and 1000V DC. Do not use this device on standard AC electrical circuits.
- How do I mount this surge protector and does it require extra parts?
- This unit snaps directly onto a standard 35mm DIN rail for quick installation. You will need to install an external backup fuse to keep the system safe. It connects in common mode, running from line to earth or ground.
- How do I choose between the different voltage and discharge current options?
- Select a voltage rating that matches or slightly exceeds your DC system's maximum continuous operating voltage. Choose the 40kA maximum discharge option if you live in an area with frequent lightning. The 20kA model works well for lighter industrial or residential setups.
