Modified wave power inverter 24V to 220V 500W

Power converter with the following characteristics: Input voltage: 24 V DC. Output Voltage: 100, 115, 220, 230 or 240 V AC. Continuous Power: 500 W. Peak power: 1200 W. Output frequency: 50 or 60Hz No load consumption: 0.6 A. Efficiency: 90%. Fuse: 2 x 30 A. Bipolar has a plug connector that supports round (220) and planes (110V), in the same connector and one plug bipolar + ground (typical Schukor female). Dimensions (WxDxH): 200x130x60mm. Weight 1.10 Kg Includes cables to connect directly to the car battery. Works with most appliances that do not exceed the inverter power (microwaves, motors, lamps, computers, etc..). The rectified waveform does not support some electrical appliances that require high consumption peaks (refrigerator, microwave, etc..). Are investors meconomic ore but can not connect high drain devices or requiring a pure wave.
