Transformerless Three-phase Inverters Powador 10.0

Imagine perfect grid current – the kind you get from large-scale power plants – but from decentralised renewable sources. The Powador 10.0 TL3 to 14.0 TL3 units combine KACO‘s many years of experience in developing transformerless units with the demand for perfect grid feeding. Since they are true three-phase units, they provide high-quality, sinusoidal alternating current with a 120-degree phase shift – a dream come true for all grid operators.These units give you a lot of flexibility in designing your PV system. They operate with two separate MPP trackers to allow for optimum adjustment. Two strings can be connected for each DC/DC actuator, which means that the units can process the solar power from four strings. The input voltage window is extremely wide: 350 to 800 V. The peak efficiency is more than 98%. Cooling is provided by demand-driven fans that are aimed directly at the temperature-sensitive components. It is easy to achieve perfect communication with the three units. In addition to the normal RS485 interface, which enables you to query yield data with the Powador-proLOG, they offer innovations that provide a lot of convenience: an integrated web server for uninterrupted monitoring via Ethernet, a USB connection for installing software updates and downloading all log data, as well as a graphic display to view operating data. The new housing makes the units compact and simplifies installation. A number of country-specific default settings are programmed into the inverters. These are easy to select during on-site installation. Your choice of operating language is independent of these settings. Available for delivery as of January 2011.
