Perfect for your wind, solar, or hybrid systems, this controller combines intelligence, reliability, and energy efficiency.

This hybrid charge controller allows simultaneous management of a 3-wire wind turbine with a maximum nominal power of 800W and a photovoltaic installation up to 300W, to charge a 12V battery bank.

It monitors the battery voltage, controls the charge from both energy sources, and automatically commands the electric braking of the wind turbine when safety thresholds are reached. Its display, operating indicators, and manual braking switch facilitate installation control.

This 12V hybrid controller centralizes the management of an autonomous installation combining wind and solar energy.

The wind turbine connects directly to the three terminals provided on the controller. The three conductors correspond to the three phases of the wind generator and do not have positive or negative polarity before being processed by the controller. Their connection order does not affect the operation.

The 12V mention corresponds to the nominal voltage of the battery bank. It does not mean that the generator provides a fixed voltage of 12V on its three wires. The voltage produced by the wind turbine varies according to its rotation speed and must remain within the permissible limits of the regulator.

The regulator also has a positive and negative input for photovoltaic panels as well as terminals dedicated to the 12V battery bank.

During operation, the device monitors the battery bank voltage and interrupts charging when the maximum threshold is reached. It can also control the braking of the wind turbine in case of a charged battery, excessive turbine speed, or controller safety activation. The braking is gradual to limit mechanical stress on the wind turbine.

The display allows you to check the measured voltage. The displayed percentage is associated with the operation of the wind brake and should not be considered as an accurate measure of the battery's state of charge.

The braking parameters are factory-set and the display is locked to prevent any unintentional changes.

To ensure proper convection cooling, the regulator must be installed vertically, with the connections facing downward.

Display and indicators

The display notably indicates the current voltage of the battery park as well as a percentage related to the activation of the wind brake.

This percentage does not constitute an accurate indicator of remaining capacity or battery charge status. The use of a separate battery monitor or wattmeter is still necessary to accurately measure production and charged energy.

The yellow indicator shows that the battery is connected and the system is powered.

The red light comes on when the wind turbine braking is activated.

When the display flashes during a braking phase, pressing the central button stops the visual alarm from flashing.

Recommended use

This regulator is intended for standalone or hybrid installations operating with a 12V battery bank, for example:

• cabin or off-grid dwelling;
• wind turbine installation with storage;
• hybrid wind and photovoltaic system;
• power supply for small equipment from a battery bank;
• installation requiring automatic braking of the wind turbine.

The 800W power refers to the maximum nominal power allowable for the wind turbine.

It does not correspond to a permanent production of 800W.

The actual available power varies notably according to:

• the actual wind speed;
• the height of the wind turbine;
• the presence of obstacles;
• the turbulences;
• the generator model;
• the length and cross-section of the cables;
• the condition and capacity of the battery;
• the electrical losses;
• the general installation conditions.

Any production estimate should therefore be considered indicative and not as a guarantee.

Wind turbine connection

The compatible wind turbine uses three output conductors.

These three wires correspond to the three phases of the wind turbine generator. They do not have a positive or negative terminal before being connected to the regulator.

The order of the three wires does not affect the operation.

Installation and safety recommendations

The connection must be made with the power off, following the provided instructions and respecting the appropriate electrical protections.

The battery bank must be connected to the regulator before the wind turbine and solar panels.

The connection between the regulator and the battery should be as short as possible, with a recommended copper section of 6mm² and a maximum recommended distance of 3 meters.

The three wires of the wind turbine generator can produce a high voltage when the rotor is turning, even if they are not connected to any device.

They must never remain accessible or be handled when the wind turbine is in rotation.

Before any intervention, the wind turbine must be mechanically immobilized or secured according to the manufacturer's procedure.

Electrical braking can significantly slow down the turbine without necessarily completely immobilizing the rotor.

This product is not intended for direct injection into the 230V grid.

It must not be connected directly:

• to a solar MPPT;
• to a portable power station;
• to a battery without regulation;
• to a converter;
• to an inverter not designed for wind power.

Important information

A three-wire wind turbine generator generally provides a variable three-phase alternating current before rectification.

The three conductors do not have positive or negative polarity before being processed by the regulator.

A diode bridge does not replace a charge regulator.

A solar MPPT regulator does not replace a wind regulator.

For batteries, the entire chain must maintain a common voltage of 12V, with appropriate protections and wiring.
