At 7000 watts and up to 14000 watts for 9 seconds the Industrial Grade Modified Sine Wave Power Inverter promises to be a complete solution for most any power need you present. From recreation to industrial applications and backup emergency power needs this 7000 watt modified sine wave inverter delivers enough durable power for high end equipment that requires substantial electricity. This digitally outputted and phase corrected inverter is the recommended power solution for clean reliable output without noise or distortion. Delivering an incredible 7000 watts of continuous power this utility-grade inverter was designed to create a stable AC power source. This inverter supplies ample power to run large pumps compressors power tools multiple appliances job sites and even a small house! It has PWM programming which corrects any fluctuation in voltage or frequency caused by battery fluctuation or sudden surges in power usage. It also has a longer than average surge time (9 seconds when over 7000 watts). Features: 7000W max continuous power Modified sine wave Power switch LED is also a self test light - Green Overload fail LED - Red Over Temperature LED indicator Over Load LED indicator 1 AC receptacles 240 volt Direct connect terminal block for full load applications On/off switch Over Temperature protection Over Load protection Thermally controlled fan DC volt Meter - Input meter Percent load usage LED bar 5 Externally located re-settable circuit breakers (60amp) ac output short circuit protection Aluminum case for optimal cooling Pre-wired for remote on/off switch Pre-slotted mounting plate Instruction manual Free 1 year tech support 1 Year Warranty Parts and Labor Specifications: Continuous output power: 7000 Watts Surge power capability (peak power): 14000 Watts The surge duration is electronically controlled and permits up to 9 seconds while the output is between 7000 and 14000 watts. During this time the buzzer will sound until the inverter electronically shuts down. dc input / operating voltage: 20-30 Volts Output voltage: 247 Volts ac +/- 10% Output wave form: modified sine wave with phase correction Output frequency: 60 Hz +/- 1 Hz Battery low voltage alarm: 20 +/- 0.5 Volts Battery low voltage shutdown: 19.5 +/- 0.5 volts High input voltage protection 34 +/-0.5 volts No load current: 200mA Start up AC amps: 58 Continuous AC amps: 29 Full load efficiency: 90% Auto Cooling Fan Start at 107 degrees F Full load maximum operating temperature: 163 degree F AC Output Socket Type: single 240 volt plug Internal fuse protection Product size (D x W x H): 21.26" X 8.43" X 5.35" Weight: 26.5 lbs.
