wind/solar hybrid power controller and inverter

Description

***** and control AC output from wind turbine invert to DC, then with solar panels charging power to storage battery, if the power is superfluous, PWM mode will discharge the superfluous power and keep the storage battery’s voltage at floating charging voltage to make full use of the electrical power and prolong the service life of the battery. 2. DC to AC invert output After turning on the “IVT SWITCH” on front panel, inverter invert the storage battery DC to pure sine wave AC, output from “AC OUTPUT” 3. Over voltage protection When storage battery voltage over “OVER VOLTAGE”, equipment will cut off inverting output, “ OVER VOLTAGE” shows on the LCD, alarm will buzz for ten seconds. When the voltage reaching to “ OVER VOLTAGE RECOVERY”, inverter will recover to work. 4. Under voltage protection When storage battery voltage under “ UNDER VOLTAGE”, equipment will cut off inverting output in order not to damage the battery, “UNDER VOLTAGE” shows on the LCD, alarm will buzz for ten seconds. When the voltage reaching to “ UNDER VOLTAGE RECOVERY”, inverter will recover to work. If there is switching device, it will switch to city electric when over-discharge. 5. Over load protection If AC output power over rated power, equipment will cut off inverting output automatically, “ OVER LOAD” shows on LCD, alarm will buzz for ten seconds. Turn off the “IVT SWITCH”, ”OVER LOAD” disappear, before you turn on “IVT SWITCH” pls check if the load is normal. 6. Short circuit protection If AC output short circuit, equipment will cut off inverting output automatically, “ OVER LOAD” shows on LCD, alarm will buzz for ten seconds. Turn off the “IVT SWITCH”, ”OVER LOAD” disappear, before you turn on “IVT SWITCH” pls check if circuit is normal. 7. Over thermal protection If the temperature is too hot in equipment, equipment will cut off inverting output automatically, “ OVER TEMPERATURE” shows on LCD, alarm will buzz for ten seconds.
