DC 1000V Surge Protector for Photovoltaic Systems
The LAD1-C40 surge protector safeguards photovoltaic systems against voltage spikes caused by lightning, electrostatic discharges, and grid fluctuations. Mounted on a DIN rail directly in the solar installation's electrical panel, this device ensures continuous operation of the inverter, modules, and storage systems, preventing costly damages. With a maximum operating voltage of 1000V DC, it is compatible with most residential and commercial photovoltaic installations.
What you get with this product
- Immediate protection of the inverter and solar panels against overvoltages from lightning — you avoid costly equipment replacements
- Integrated thermal safety that automatically disconnects the device when the overvoltage exceeds the permissible limit — no manual intervention in case of an incident
- Quick mounting on standard DIN rail — installs directly into the existing electrical panel, without additional modifications
- Reliable operation in extreme weather conditions thanks to the robust housing and construction compliant with IEC 61643-11
- Visible status indicator — you can check at a glance if the device is operational or needs replacement
- Compatible with photovoltaic systems up to 1000V DC, covering series panel configurations specific to residential and prosumer installations
How it works and how to install it
The LAD1-C40 protector works by diverting dangerous voltage spikes to the ground before they reach the sensitive components of the photovoltaic installation. The device is mounted on a 35mm DIN rail in the DC panel of the solar system, connecting in parallel on the direct current line between the panels and the inverter. Installation is straightforward and does not require special tools — a certified electrician can complete the mounting in minutes.
Frequently Asked Questions
Is this surge protector compatible with any solar inverter?
Yes, the device is compatible with any inverter that operates on direct current up to 1000V DC, including common brands of string inverters used in residential and commercial installations.
How often should the surge protector be replaced?
The lifespan depends on the number and intensity of absorbed overvoltages. The visible status indicator clearly signals when the device has exhausted its protection capacity and needs to be replaced.
Is it mandatory to install a surge protector in a photovoltaic system?
Current technical regulations recommend installing surge protection in all grid-connected or storage-equipped photovoltaic installations, especially in areas with high atmospheric electrical activity.
