Note: The system lightning protection does not guarantee that the equipment will not be 100% damaged by lightning; the power system must be multi-level lightning protection;
The complete lightning protection system includes external lightning protection and internal lightning protection. External lightning protection refers to: lightning receptors, down conductors, and grounding bodies, which are mainly used to defend against direct lightning strikes. Internal lightning protection includes: shielding, reasonable wiring, safe distance, equipotential connection, overvoltage protection, etc., mainly used to prevent lightning induction, ground potential counterattack, lightning wave intrusion, etc.

Application

●AC/DC distribution
●Power supplies
●Industrial automation
●Telecommunications
●Motor controls systems
●PLC applications
●Power transfer equipment
●HVAC applications
● AC drives
●UPS systems
●Security systems
●IT/Data centers

Tip: Lightning protection is probabilistic protection, and we cannot provide 100% protection.

First, lightning discharge itself has a certain degree of randomness, and lightning parameters have certain statistical properties, which determines that all protective measures based on these statistical characteristics of lightning parameters cannot provide 100% protection. Such as: direct lightning protection-shielding characteristics; lightning current amplitude, waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all interference voltages/currents. The fundamental purpose of taking protective measures is to ensure that most of the energy caused by interference does not spread to the vulnerable parts of the device and the staff.
Finally, the cost of protection against high-level surges with a small probability of occurrence has risen sharply.

One easy solution

With this solution, many cells in power plant and residential application have been protected. If you don't protect your cells, in case of several big surges, your cells will be completely damaged and in case of many small surges without visual damages for you, your effciency will go down over the years. You should use a surge protection to have a better return on investment. Class C surge protection for photovoltaic

OBV5-C40-PV DC series are Class C Surge Protection Devices, they designed to protect against lightning surge voltages in photovoltaic power supply networks. These units must be installed in parallel on the DC networks to be protected and provide common and differential modes protection. The OBV5-C40-PV DC series are availa-ble for the main operating voltages in photovoltaic : 500, 600,800,900 and 1000 Vdc. The use of Class C Surge Protection Devices are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long. The electrical diagram of the OBV5-C40-PV DC series are based on high energy MOVs equipped with specific thermal disconnectors and related failure indicators. A remote signal feature is also available
The OBV5-C40-PV DC series are made with plug-in modules to allow a fast and easy maintenance in case of fa-ilure (disconnection from the DC network).

Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):

Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.
