I. OFF GRID CHARGING CONTROLLER is wind turbine/solar panel auto-controller is special matched equipment with wind turbine or solar power. It commutates the AC that generated by wind turbine to DC and then charges to storage battery groups.

II. OFF GRID CHARGING CONTROLLER which is auto-controller has a beautiful appearance, simplify indication, and it is easy to operate. It has a protection of the converse connection of the batteries. The wind turbine will unload automatically when the batteries voltage reach to 125% of the normal voltage; and the wind turbine will resume working when the batteries low down to the 108% of the normal voltage. The user can adjust the potentiometer to change the unload voltage. The key component adopts the high-efficient chip control, the complete machines is intelligent. This system is running safely, steadily, and reliably, working efficiently and have a long work life, which is proved by a large number of experiments.

III. Manual brake switch

1. After connected the storage battery correctly, press the button to "ON" position in the back panel, the turbine is under the condition of automatic working. (Small power controller with this equipment, larger power charger controller user will self-provided to install)

2. Press the wind turbine button to "OFF" position when without using this machine.

3. When the controller which rated power is above 3kw, it is forbidden to operate the manual breaking switch when the wind turbine is working.

I. Grid Connection/On Inverterthe function is rectifying the 3-phases AC which getting from the wind turbine to DC power for the inverter and control utility grid using.

II. Grid Connection/On Inverter is easy to use，With over-voltage automatic unloading when too big wind；when grid on inverter failure or dropped, automatic unloading into the PWM mode, and automatic voltage regulator; after 100% unloading if the DC voltage still be higher than the value of requirement voltage, the controller will brake the wind turbine automatically, after 12-20 minute delay the brake cessation, the wind turbine started to run。It also has, the elimination of brake delay function, manual brake function, wind energy instruction, unloading instructions, delayed shutdown instructions, low-voltage instructions, grid electricity instructions. After more testing it have proved this system have security, stability, high efficiency, long service life the feature.

III. Manual brake switch

2. Press the wind turbine button to "OFF" position when without using this machine.

3. When the controller which rated power is above 3kw, it is forbidden to operate the manual breaking switch when the wind turbine is working.
