12V 24V 48V MPPT Wind Turbine Solar Panel System Controller 2800W 2200W 2000W 1400W 1200W Hybrid Wind Solar PV Charge Controller

Protection

Explanation

Reversed charging Protection of solar

Such as at night, the voltage of the battery may be higher than solar panel. The controller protect the battery from charging the solar panel.

Reversepolarity Protection of battery

When the battery polarity is reversed, the controller does not work and there is no display. The fuse protects the internal circuit.If the battery does not work properly after it is connected correctly, just need to replace the fuse .

Battery open circuit Protection

After long-term use, the battery may be Open-Circuit or poor connect. The controller can protect itself from damage.Check the connection regularly.

Over voltage
Over current
Over load voltage Protection

When it’s strong wind or over voltage, the controller will automatically start braking function to protect the wind generator and battery. The controller will automatically cuts off the circuit when the output is over voltage.

Lightning Protection

Lightning protection refers to the last level of protection necessary for equipment. For lightning-prone areas, special lightning protection devices and other components of the multilevel lightning protection system are needed. It need additional payment If the user need this function.
