The Radius 20k/25k guarantees operation at the full power rating up to ambient temperatures of 50°C and a voltage range of up to 1000 Vdc.
This latest generation inverter complies with the most stringent EMC requirements (Class B).
The Radius 20k/25k is available in the cabinet version with integrated isolation transformer, anti-islanding protection and overload switch.
This means the AC panel could not be installed downstream of the inverter.
With a maximum operating voltage of 1000 Vdc this solution achieves considerable savings in terms of wiring and allows several modules to be connected to each string, thus reducing the number of strings.
This also results in less power loss, further enhancing the efficiency of these high-performance RADIUS inverters.
