## Summary description

Eti-Polam ETITEC M T12 PV 1100/12.5 is a surge arrester designed for photovoltaic (PV) systems, combining Type 1 and Type 2 protection with class B/C rating. It provides overvoltage protection for PV arrays and inverter inputs, with parameters indicated by model designation 1100/12.5. Used to protect DC circuits and equipment from transient overvoltages in solar installations.

## Long description

Eti-Polam ETITEC M T12 PV 1100/12.5 is a surge arrester developed for photovoltaic (PV) systems to protect DC circuits and connected equipment from transient overvoltages. Combining Type 1 and Type 2 protection with a class B/C rating, this device is intended for installation at PV array outputs and inverter inputs to reduce the risk of damage from lightning-induced surges and switching transients. The model designation 1100/12.5 indicates the product's nominal voltage and discharge characteristics relevant to solar installations.
Advantages
The surge arrester integrates Type 1 and Type 2 protection in a single unit, providing both direct lightning impulse handling and protection against lower-energy transient overvoltages. Its class B/C rating aligns with common PV system protection levels, enabling coordinated protection with upstream and downstream protective devices. The compact design allows installation close to string combiners or inverter DC inputs, and the device is built to operate on DC photovoltaic circuits, maintaining stable protection performance under typical PV voltages and conditions.
Suitable for
Protection of PV array strings and string combiners from transient overvoltages
Protection of inverter DC inputs and junction boxes in solar power systems
Use in rooftop and ground-mounted photovoltaic installations
Integration into PV system protection schemes where Type 1+2 protection is required
Key specifications
Protection type: combined Type 1 and Type 2 (class B/C)
Application: photovoltaic DC circuits
Nominal characteristics indicated by model: 1100/12.5 relevant to system voltage and discharge capability
Designed for installation at PV array outputs and inverter inputs
Compact form factor suitable for mounting in combiner boxes or near inverters
How to use
Install the surge arrester close to the protected point, for example at the output of string combiners or at the DC input terminals of the inverter, following local electrical codes and the manufacturer's installation instructions. Ensure correct polarity and proper DC connection to the positive and negative PV lines, and provide a low-impedance equipotential bonding to the system grounding. Verify that the arrester's nominal voltage characteristics match the PV system voltage before energizing. Regular visual inspections and periodic checks of connection integrity are recommended to confirm continued operation.
Usage recommendations
Use this device as part of a coordinated surge protection scheme: combine it with upstream and downstream protective devices rated for the same protection class, maintain good grounding practice, and follow installer and system manufacturer guidance to ensure effective protection of PV components.
