4000W 48V lithium charge controller Ista-Breeze

charge controllers for wind turbines

This powerful charge controller is specifically designed for wind turbines and optimizes the charging of lithium batteries. It offers effective protection through reverse polarity and short circuit protection and has an integrated LCD display that shows amps, watts and battery voltage. The external aluminum cooling fin design ensures excellent heat dissipation, while the built-in turbine brake minimizes mechanical shock.

Note: After purchase, please be sure to send us the datasheet for your lithium batteries to ensure that the charging voltage is set correctly.

Perfectly tailored to the needs of lithium batteries in your wind turbine.



The LCD display is located in the controller.
