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.




Works like an opposite direction UPS

  • The ATS controller will switch to grid power when batteries are lower than the user define.
  • Auto distinguish:DC 12/24/48V,AC 100-120V 60HZ / 220-240V 50HZ auto distinguish.
  • User can define the Cut-Off and Recovery Voltages.

Beneficial to solar and wind system

  • When cloudy or windless days and your battery get low,automatic switching to grid power,Take over your battery.
  • BIG POWER:5.5kw(110V) or 11KW(220v),
  • Fast Transfer time:Inverter transfer to public power ≤ 10ms,public power transfer to inverter ≤ 16ms
  • Please tie the ground wire together.

Application Area

  • In applications where there is a stand-alone solar or wind system with an available AC mains supply(utility power),one can choose to use the energy stored in the battery(IES) first and when the inverter disconnects due to a low voltage battery,the controller automatically transfers the loads to the mains(utility power).


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
