Product Briefing Outline: KACO new energy has launched new inverter models within its XP series. The new Powador XP200-HV and Powador XP250-HV TL central inverters complement the 100 and 350-kilowatt inverters currently on the market. These two new models have output power ratings of 200 and 250 kilowatts. Two XP250 units can be integrated into a lightweight steel enclosure for the new 500-kilowatt station.
Problem: Large-scale solar inverters need to be highly efficient and reliable to meet high performance requirements of customers. The ability to offer a range of systems that better scale with a given project allows greater flexibility for project developers meeting plant expectations.
Solution: Like all of the products in this series, the new XP inverters feature full-digital controls. The intelligent control of the power electronics increases the efficiency of the power transistors. A variety of pulse width modulation techniques can be used depending on the input power. The inverters are capable of delivering reactive power. New standards can be implemented at any time. The two new inverters are also flexible when it comes to system sizing. Powador XP200-HV comes with a transformer and Powador XP250-HV TL without. This makes the XP200 ideal for a direct feed into a low voltage grid. One or more XP250 inverters can be used in combination with a suitable transformer for input into a medium voltage grid.
Applications: Commercial and large-scale solar plants.
Platform: The Powador Series has a maximum input current is 467 or 611 amps with a maximum input voltage of 1,000 volts. The max rated efficiency of the XP200 is 97.4 percent. For the XP250, this figure is 98.2 percent. The MPP range is from 450 to 830 volts. Pre-configured, country-specific grid parameters make it easier to set up initial operation on-site.
Availability: April 2010 onwards.
