DC 12/24/48V,AC 100-120V 60HZ / 220-240V 50HZ auto distinguish.User can define the Cut-Off and Recovery Voltages.Recovery voltage must be higher than Cut-off voltage. Battery type: Suitable for Sealed,Gel,Lead-acid,Lithium battery and so on. as long as the voltage of your battery are within the voltage ranges in the followings.9-17V at 12V system;18-30V at 24V system; 30-60V at 48V system. 5.5kw(110V) or 11KW(220v),Fast Transfer time:Inverter transfer to public power ≤10ms,public power transfer to inverter ≤16ms. Battery real-time voltage;working status of public power,inverter and battery.⭐Note: The controller needs to connect the battery, powered by the battery and get battery power data. Automatic Dual Power Controller Transfer Switch for Off Grid Solar Wind System ! Product Instroduction This dual power transfer controller ATS-11KW is used between an off-grid system and public power.The controller is separately connected with public power,inverter,battery and load.On the top of the controller,there is an on/off switch,please turn on the controller after ensuring all cables are well connected. The ATS power transfer controller provides reliable operation of an inverter and AC utility power in one compact device. The ATS switches automatically between the AC utility power and the inverter, while protecting the inverter against external Voltages. Adjustable Cut-Off and Recovery Voltages 1.LV-SW:setting the switching voltage function. 2.BAT-V:normal displaying battery voltage. 3.HV-SW:setting the recovery voltage 4.12V,24V,or 48V:displaying after the system indentification. 5.LCD digital:a.battery voltage,b.low voltage setting switching voltage,c.low voltage recovery to set switching voltage. 6.Right arrow:shows low voltage switch to mains status. 7.Left arrow:shows the low pressure is restored to the inverter state. 8.LCD red no function control display,fixed display after power on. the battery icon is low battery status Parameter Rated Power:5.5kw(110V) or 11KW(220v), Input Voltage:Auto distinguish:AC 100-120V or AC 220-240 Output Voltage:Auto distinguish:AC 100-120V or AC 220-240 Transfer time:Inverter transfer to public power ≤ 10ms,Public power transfer to inverter ≤ 16ms LCD display:Working status of Public power,inverter and battery System voltage:Auto distinguish:12V or 24V or 48V BAT.Low Cut-down:Default 11V/22V/44V,adjustable BAT.Low Recovery:Default 13.5V/27V/54V,adjustable Battery type:Suitable for Sealed,Gel,Lead-acid Lithium battery and so on. as long as the voltage of your battery are within the voltage ranges in the followings.9-17V at 12V system;18-30V at 24V system;30-60V at 48V system.
