DS50VGPVS is a DC Surge Protection Device (SPD) for medium risk DC power applications up to 1200Vdc. The DS50VGPVS provides protection against the direct and indirect effects of lightning and has a unique no leakage current design. CITEL's patented hybrid Metal Oxide Varistor (MOV)/Gas-filled Spark Gap (GSG) protection circuit will dramatically increase the life expectancy of the surge protector and leave no footprint within the DC power system.

DC Power Surge Protection Overview Background and Protection Considerations

Utility-Interactive or Grid-Tie Solar Photovoltaic (PV) Systems are very demanding and cost intensive projects. They often require the Solar PV System to be operational for several decades before it can yield the desired return on investment.

Many manufacturers will guarantee a system life of greater than 20 years while the inverter is generally guaranteed for only 5-10 years. All costs and return on investments are calculated based on these time periods. However, many PV systems are not reaching maturity due to the exposed nature of these applications and its interconnection back to the AC utility grid. The solar PV arrays, with its metallic frame and mounted in the open or on roof tops, act as a very good lightning rod. For this reason, it is prudent to invest in surge protection to eliminate these potential threats and thus maximize the systems life expectancy. The cost for a comprehensive surge protection system is less than 1% of the total system expenditure.

To analyze the full threat level of the installation, we must make a risk assessment.

Operational Downtime Risk

Areas with severe lightning and unstable utility power are more vulnerable.

Power Interconnection Risk

The greater the surface area of the solar PV array, the more exposure to direct and/or induced lightning surges.

Application Surface Area Risk

The AC utility grid is a likely source of switching transients and/or induced lightning surges.

Geographic Risk

Consequences of system downtime are not only limited to equipment replacement. Additional losses can result from lost orders, idle workers, overtime, customer/management dissatisfaction, expedited freight charges and expedited shipping costs.

Recommend Practices

Earthing System
Surge Protectors shunt transients to the earth grounding system. A low impedance ground path, at the same potential, is critical for the surge protectors to function properly. All power systems, communication lines, grounded and ungrounded metallic objects need to be equipotentially bonded for the protection scheme to work efficiently.

Underground Connection from External PV Array to Electrical Control Equipment

If possible, the connection between the external Solar PV Array and the internal power control equipment should be underground or electrically shielded to limit the risk of direct lightning strikes and/or coupling.

Coordinated Protection Scheme
All available power and communication networks should be addressed with surge protection to eliminate PV system vulnerabilities. This would include the primary AC utility power supply, Inverter AC output, Inverter DC input, PV string combiner and other related data/signal lines such as RS-485, 4-20mA current loop, PT-100, RTD, and telephone modems.
