The Citel DS220DC series is designed to protect 12V, 24V, 48V and 150V DC power lines for an off-grid PV system. The surge protectors protect the charge controller and other system electronics. DS220DC automatically reset after each lightning surge or electrical transient. These surge arrestors clamp at much lower voltage than Delta surge arrestors at left so they offer much better protection for charge controllers and inverters in low-voltage DC systems.

Citel PV surge protectors are DIN mount and are ideal for placement inside combiner boxes.

DC Power Surge Protection Overview

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.


NOTE: This product should be installed in a separate enclosure. For installation in the main panel, use the EG3010. eGauge is an affordable, flexible, secure, web-based electric energy and power meter that can measure up to 12 circuits on up to 3-phases (120V-480V, 50-60Hz). Use it to measure and record total building electrical consumption, solar, wind, consumption of individual circuits, such as appliances or geothermal system pumps, and motors. eGauge is best suited to provide: Real time energy information Renewable Energy monitoring Measurement and Verification of essential equipment (M&V) Operations and Maintenance of asset portfolio (O&M) Data export via push or pull with an open data API Lower energy cost Lower emission associated with fossil fuel energy Establish building energy benchmark and LEED points Peak Demand analysis Energy Efficiency projects and commissioning
