Inverter KACO Powador 7900 INT
The Powador 7900 units are equipped with digital controllers so that they can be used internationally. The appropriate country settings can easily be selected on-site; the country-specific settings are stored in the software, so the inverters can be quickly and easily installed anywhere in the world. The menu language can be selected independently from the country-specific settings. The units are also equipped to comply with the pending Low Voltage Directive.
The units include transformerless topology without a step-up converter. DC disconnects and string fuses are already integrated. This provides maximum safety and reliability for the system operator and makes the installer's job easier. These inverters are designed as a trio, with each unit feeding into one of the three phases. This allows each unit to optimally utilise the voltage range of a photovoltaic system that has been divided into three sub-generators. The integrated Sym-Bus ensures that any potential asymmetry does not exceed the maximum permitted limit of 4.6 kW, even when there is a fault in a unit. They represent an alternative to central inverters (depending on the system design). Since all of the transformerless string inverters can also be combined with one another as required, they allow you almost unlimited freedom in planning, from 2 kW up to the mega-watt class.
