SIRO Wind Turbine Controller 1500W/2800W/5000W 48-240V DC PWM Display LCD

The SIRO controller is a professional-grade charge controller designed specifically for off-grid wind turbine systems. It supports wind turbines with power ratings of 1500W, 2800W, and 5000W, making it a versatile solution for small to medium wind energy installations. The controller features an intelligent PWM charging algorithm, automatic and manual dynamic braking, and a comprehensive LCD display for real-time monitoring of voltage, current, power, and battery status. Built with a durable aluminum alloy housing and natural air cooling, it ensures reliable operation in demanding environments.

Advantages

Configurable for multiple turbine power levels (1500W, 2800W, 5000W) and battery voltages (48V, 96V, 120V, 240V DC). High efficiency >97% and low quiescent current <20mA. Multiple protection features including overcharge, over-discharge, reverse polarity, short circuit, over-current, lightning, and overspeed. Optional RS485 communication for PC monitoring.
