422 ... 528 V AC
AC nominal frequency
Operating range 60 Hz
59.3 ... 60.5 Hz
Max. AC current 601.4 A AC (at 480 V AC)
Inverter technology True sine wave, current source, high frequency
PWM with galvanic insulation
Max. operating altitude 13,000 ft. (4,000 m) above sea level
Power Reduction:
The Sunny Central can function without power
reduction up to 3,300 feet (1,000 m) above sea
level. At higher altitudes the power is reduced by
5 % per 3,300 ft (1,000 m).
Ambient temperatures -13 °F ...113 °F (-25 °C ... 45 °C) (without
power reduction)
-13 °F ... 122 °F (-25 °C ... 50 °C) (with power
reduction)
Output power at 122 °F (50 °C) = approx.
347 kW
Cooling Temperature-controlled fans for cooling. Easily
removable filters, easily accessible.
