Performance Description
Ø PWM Charging Mode: When the battery power is full, adopting the PWM control mode to control the charging, which can not only charge the battery effectively, but also prevent the battery from overcharging and prolonging the service life of the battery.
Ø Friendly human-machine interface: Display wind solar hybrid system state and parameter with intuitive figures and graphics, including: battery voltage, wind turbine voltage, PV voltage , wind turbine power, PV power, wind turbine current, PV current, state of charge of battery. You can check the display content by the LCD four button.
Ø Perfect protection function：Battery overcharge, over discharge, anti-reverse protection; wind turbine current limiting, brake automatically and brake manually protection; PV anti-charge, anti-reverse protection; lightning protection and so on.
