1. Important Safety Warning
Before Using the controller, please read all instructions and cautionary markings on the unit
and this manual. Store the manual where it can easily be accessed.
This manual includes all safety warnings, installation, and operation guidance of SWS series
wind&solar hybrid controllers.
Before installing and using this controller, read all instructions and cautionary markings on the
controller and all appropriate sections of this guide.
Do not use the machine in the place where has flammability and explosive gas/articles. Beware
of flames and sparks.
Please Contact our after-sales person if the machine doesn’t work.
Do not change the electrical components and parts yourself, or we will not be responsible for the
warranty items and related duties.
Please install the machine indoor to avoid the rain water enter the controller inside.
Please keep good ventilation and heat dissipation.
Please install a circuit breaker outside the controller if conditions are allowed.
Please use copper cable for line connection, and choose the right diameter of cable according to
the actual current.
To avoid a risk of fire and electric shock, make sure the existing wiring is in good condition and
that the wire is connected tightly.
Do not restart the controller immediately when it alarms. Please analyze the fault reasons and
repair them at first.

3. Product Installation
3.1 Installation Notes
1) The machine should be kept indoors and well ventilated;
2) Environment temperature: -20～+40℃; Humidity: <=95%，no condensing
3) Altitude should not be more than 40000m。（when the altitude is more than 1000m, the machine
should be used according to the GB/T3859.2 regulations）
4) Avoid using the machine in direct sunlight, sun exposure, rain, humidity, acid fog, and dust.
5) To guarantee the lifespan, it is suggested that the space around the device has no other items
within 30CM.
6) The machine can only charge for the battery in the rated voltage range.
7) The machine can only be connected to the wind turbine and PV with allowed power and
voltage.
3.2 Installation and Wiring
3.2.1 Installation Steps
Please refer to the specific installation situation. Generally speaking, if it is used in street light pole,
you can fix the controller to the rail inside the light pole.
If it is installed in the power box, the power box is drilled according to the hole size, and the
controller is fixed with M4 screw.

Please connect those parts according to the order of ①-④, and notice the following items.
1) Connect the load positive and negative terminal to the “DC OUTPUT” terminals
as“+”“-1”“-2”relatively. 2 output loads share the same “+” terminal.
2) Connect the battery bank to the controller by the terminal which marks “BATTERY”. (do not
reversed the connection of positive and negative terminals)
3) When wind turbine is still or running in a low speed, connects its output cable to the “WIND
INPUT” terminal on the controller.
4) Connected the terminals of solar panels to “SOLAR INPUT” terminals “+”“-”on the controller；
5) Check all the connection to make sure they are connected rightly and tightly.
4. Operation Interface Introduction
