Sunny Central CP inverters are also available with an industry-best 99% uptime guarantee and optional extended warranties up to 20 years.

PV inverter manufacturer SMA America has released a new line of solar inverters, the Sunny Central Compact Power (CP) line. This outdoor-rated line includes the Sunny Central 500CP, 630CP, 720CP, 760CP and 800CP, which won the Intersolar Award 2010 in the photovoltaics category. These inverters join the Sunny Central High Efficiency (HE) line in SMA’s North American utility-scale lineup.

“With industry-leading power output and efficiencies of 98.6 and 98.7 (630CP) percent, the Sunny Central CP inverters are the ideal building blocks for utility power plants of any size,” says Jurgen Krehnke, president and general manager of SMA America. ”They are available for delivery to our North American customers.”

The manufacturer says its Sunny Central CP features a compact design that not only makes it easy to load and transport, but also able to be installed almost anywhere, providing integrators with a variety of configuration options. The outdoor-rated CP series inverters can be placed on a simple concrete pad or under a basic shade structure. Two Sunny Central CP inverters can be combined with one medium voltage transformer to provide up to a 1.6-MW packaged skid solution, which simplifies large-scale deployment.

In addition to protecting against chemical-aggressive environments, the inverter’s weatherproof enclosure is partitioned to shield sensitive electronics from dust and debris. These two sections are cooled by direct ventilation and a heat exchanger via SMA’s  active temperature-management system, which allows the Sunny Central CP inverters to maintain full power in ambient temperatures up to 122 F. In temperatures below 77 F, their peak continuous power is 110% of rated output, resulting in increased yields and a lower levelized cost of energy.

Integrated grid management features such as remote control of active and reactive power; automatic over-frequency response; automatic power factor adjustment; power curtailment; and low voltage ride through provide system operators with essential grid stability tools, making Sunny Central CP inverters grid-friendly. SCADA options via modbus and the SMA OPC Server ensure optimum communication and control.

Another cost-reducing feature found in the CP line is SMA’s intuitive Optiprotect technology, which monitors up to 1,600 individual strings for potential failures while differentiating between extended and temporary disturbances. An auto-adaptive start-up, without configuration, and a short automated learning phase simplify and shorten installation.
