IstaBreeze IST-REG-48V-2000W Hybrid Controller (48 V, 2000 W)

The IstaBreeze IST-REG-48V-2000W hybrid charge controller is designed for coupling three-phase wind turbines with solar modules in 48 V battery systems. The device features a solid-state design with no electromechanical relays, increasing system reliability and ensuring smooth turbine braking.

The IstaBreeze IST-REG-48V-2000W hybrid controller allows for the direct connection of a wind generator with a maximum output of 2000 W and photovoltaic panels up to 600 W. The device monitors the 48 V battery voltage and disconnects the energy sources when fully charged, preventing overcharging. The entire circuit is housed in a metal casing that efficiently dissipates heat from the electronic components. The controller is equipped with reverse polarity protection, reverse current protection, and an integrated manual brake switch.

Key Features

• Solid-state design without electromechanical relays for extended system lifespan.
• Automatic and manual braking of the wind turbine in case of overspeed.
• Built-in reverse polarity protection for the battery and solar panel.
• Two LED operating status indicators.
• Reverse current protection for solar panels at night.
