Overview

300W wind turbine controller has intelligent protection function, sealed and waterproof design, with battery overcharge, overload, fan current limiting and automatic brake protection.

Specification:

Model ATO-WTCMPPT-300
Rated Voltage 12V/24V (Automatic recognition voltage)
Wind Generator Rated Power 300W
Protection Overcharge, overdischarge, reverse connnection of batteries,overloading, lighting, current control, automatic braking
Function MPPT Charging
Unloading Way PWM electrodeless and noiseless unloading
Working Temperature -20~+60°C 35~85%RH
Dimension 80*80*15mm
Net Weight 0.4kg

Note: The controller needs to be selected according to the power of the wind turbine and the battery voltage.Max voltage setup: 12.4V for 12V batteries, 29V for 24V batteries, and 58 for 48V batteries.

Features:

1. High quality technical components ensure the stability and reliability of the wind turbine controller.
2. Waterproof and dustproof, the controller can be used in various outdoor environments.
3. Voltage/current control charging ensures that the battery is always charged.
4. The MPPT charging effect is to collect electrical energy from the generator and charge the battery.
5. Use PWM to unload excess electron energy to protect the battery and ensure the safety of the wind generator.

300W controller runs quietly with no obvious noise.
This 300w wind turbine controller does the job. The MPPT charging function helps get the most out of my setup, and I like that it auto-recognizes 12V/24V. So far, it’s effortlessly handling different weather conditions.

The PWM unloading can be a bit finicky at times
The 300w wind turbine mppt charge controller works great for my small setup. I love the mppt charging feature, which boosts the efficiency. However, I wish the manual was more user-friendly. Overall, it's reliable and efficient but could use a bit more polish in its design.

MPPT controller display is quite clear
Nice MPPT charger, after a two-week power cut this solar controller is performing well on my 12v 300w setup. Plan to expand with more panels and another unit soon and possibly use 24V and run more panels.

Awesome MPPT controller
It worked perfectly with one solar panel 70watt and 250watt wind mill. To charge my gate opener that runs on a 12v car battery. It keeps at about 15V.
