JCSPV Surge Protection Devices: Safeguarding Solar PV Systems Against Electrical Surges

Even though clean renewable energy offers significant benefits, it’s important to note that Solar photovoltaic (PV) systems are quite vulnerable to being affected by indirect lightning strikes or other electrical disturbances. If surge protection isn’t in place, it can lead to expensive repairs and loss of potential energy production.

Surge protective devices (SPDs) are known to be one of the easiest ways to protect electrical solar installations from surges. The JCSPV Surge Protection Devices, in particular, are well-suited to ensure that PV systems remain equipped to perform securely even with extreme voltage spikes.

The Risks of Indirect Lightning Strikes

Indirect lightning strikes are an existing and extremely violent threat. In the context of solar arrays, these overvoltage spikes are sure to damage solar systems extensively. Allowing these voltage spikes and overvoltages into PV systems, especially those harnessing sensitive components, will lead to them being damaged, which decreases the system’s efficiency and reliability.

How Lightning Strikes Affect Solar PV Systems

Surge currents and voltages that travel through the system’s wiring are the primary cause of damage to PV systems when lightning strikes closely. These voltage spikes can lead to the degradation and destruction of solar panels, which in turn leads to losing potential energy that could be harnessed by these PV panels. These surges can also lead to insulation and dielectric failures in key components:

• Inverters: Unexpected power surges can reduce an inverter’s power output by affecting its efficiency.
• Control Units: Electrical interference can cause control unit failure, which may result in the monitoring and operation of the entire system ceasing to function.
• Communication Equipment: Telemetry and remote control become impossible when communication voltage is disrupted by a spike, resulting in communication signals being disrupted.

High Risk Areas In A PV System

A few specific components of a PV system are very sensitive to lightning-caused overvoltage. These include:

• Combiner Boxes: Surge protection is paramount at what is arguably one of the most important connection points for all PV modules.
• Inverters: Generally the most expensive component of a PV system and is significantly affected by voltage variation.
• MPPT Devices: Energy-optimizing Maximum Power Point Trackers (MPPT) increase energy efficiency but are vulnerable to electrical surges.

Protecting PV Systems With JCSPV Surge Protection Devices

To reduce the danger presented to PV systems, JCSPV surge protection devices offer the most reliable safeguard. They are designed as Type 2 SPDs, specifically preventing excessive high energy from destroying solar machinery. JCSPV covers isolated DC voltage systems for 600V, 800V, 1000V, 1200V, and 1500V DC. They also work effectively to combat lightning surges, protecting units with up to 1000Amps of short circuit airflow.

Highlights of JCSPV Surge Protection Device

JCSPV DC surge protection devices are incorporated on the DC side of PV systems. They use modern surge protection technology to protect terminal devices such as solar panels and inverters from damaging transient voltages. JCSPV surge protection devices further improve system efficiency and longevity by preventing overvoltages from influencing photovoltaic power supply networks.

Sophisticated Protection Features

Photovoltaic Surge Protection Devices feature the ability to handle PV voltages of up to 1500V DC. Other parameters include:

• Current nominal discharge: 20kA (8/20 µs) per path and 10kA (8/20 µs) for high voltage.
• Maximum discharge: 40kA (8/20 µs).
• Plugged-in module design for flexible maintenance and installation.
• Visual status indicator: Green = All is well, Red = Substitute.
• Enhanced remote indication contact for monitoring.
• High protection capabilities: ≤3.5 kV.
• Compliance with requirements of automatic secondary circuit test grids: IEC61643-31 & EN 50539-11.

Taking into account these features, JCSPV surge protection devices will ensure maximum protection for PV installations, making them an essential supplement to any solar energy system.
