Kaco inverters achieve excellent results on Photon-tests


The transformerless KACO inverter 2500xi and the Powador 4000 Supreme have sustained their position successfully during the tests of the independent PV magazine Photon in edition 11/2009. The KACO Powador 4000 Supreme achieved the best result possible for mean and high irradiation in normal operation (18 kHz) and in the Power boost mode (9 kHz). The KACO 2500xi was awarded at 2 levels: "best" result for high irradiation and "good" result for mean irradiation.

The transformerless Powador 4000 Supreme scores with following highlights:

• Power Boost on / off: 9 kHz / 18 kHz (selectable clock frequency)
• Hiighest degree of efficiency due to purely transformerless technology
• Integrated DC disconnector
• Integrated AC/DC-sensitive residual current protection
• RS232 / RS485 interface mode adjustable via controls
• Integrated potential-free fault signal
• S0 interface for control of large displays
• Protection class IP54
• Silent and maintenance-free convection cooling
• Easy installation due to mounting plate and housing doors
• LCD as standard
• Robust, reliable KACO quality
• 7 year guarantee as standard

The Powador 2500xi provides the following details:

• Integrated DC disconnector
• Integrated AC/DC-sensitive residual current protection
• Integrated potential-free fault signal
• S0 interface for control of large displays
• Highest degree of efficiency due to purely transformerless technology
• Pure convection cooling
• Easy installation due to mounting plate and housing doors
• MPP controller
