ISTABREEZE® Charge Controller 48V 4000 for Wind Turbine Generator - 2333

The Wind / Charge Controller from IstaBreeze® is an intelligent controller of the wind turbine and that controls you at the same time.

The high-end device can also be used as a monitoring system. It is used to safely and efficiently charge and control your battery with the Wind Generator.

With its discreet appearance, simple operation, with integrated protection functions, this device has high efficiency and low no-load losses.

This version of the controller will significantly increase the life and stability of the whole system, especially the batteries. In addition, the control electronics in the control cabinet monitors system voltage and brakes the wind turbine when reaching a max. Overvoltage.

The special features and product information are listed below:

  • Use of external and high quality (Triacs & Hyper Mosfet), solid state components. Increasing the life of the controller.
  • Microprocessor controlled charge with integrated voltage and current limiting.
  • Electromagnetic brake control.
  • Integrated 3-phase short-circuit switches (brake switch)
  • Protection against lightning strikes.
  • Protection against overcharging, deep discharge, short circuit, overload and against incorrect reverse polarity.
  • Integrated display.


The generator is automatically braked gently when the battery is full, modern braking system with external load resistance (Dump Load) to avoid immediate blockage of the turbine. Increasing the life of the stator.

Lcd Display is inside of controller.
