Feature: new and high quality [PURE SINE WAVE] PURE SINE WAVE INVERTER- Converts 12V/24V/48V/60V DC to AC 220V household wall power with continuous 500Watts output ( 3000Watts surge capability) with 1 AC receptacles one LED Voltage display high current DC terminals and two LED work lights. (Please make sure that the total rated power of the connected devices is 500W). [Strong and Durable] Aluminum alloy housing and high speed Intelligent cooling fan helps reduce heat . Aluminum alloy housing provides advanced protection from drops and bumps. Integrated cooling fan helps reduce heat and prevents shortages. [LED Green&Red Work Lights] When inverter work normal the two green LED Lights work but when it is on protection status the Red Led Lights will light up. [LED Voltage Screen display] LED Display shows the battery Input real-time voltage and remind you to charge your battery according to the low voltage. [Widely Applications ] Great for Christmas giftcharging TV washing machine air conditioner refrigerant Microwave and big power appliance. These can only operate a few 220V loads without interference. It can also use with in the car or solar system. [Solar system with inverter] Pure sine wave Power inverter + battery + solar charge controller+solar panel= one solar system. You can get power from solar panel and the solar charge controller help to control the charging and discharging battery help to storage energy and power inverter help you to use the solar power to the AC appliance. Which is convenience and useful when there is no power or outdoor. [Multi Protection] Built-in fuses to protect your battery and devices safe charging design safe charging technology and cooling fan prevents the car power converter provides protection against overheating under/over voltage charging overload short circuiting over temperature shutdown and less voltage audible alarm new designed DC terminals offer high current DC input. [Car Becomes RV] With our car power inverter you can use most of home appliances in your car in the open air such a watching TV playing games give you the experience like being in an RV. [Silent Intelligent Cooling Fan] Equipped with silent cooling fan it will automatically runs at different speed according to power load (watt) load and temperature for dissipating heat and reducing working noise. There is a temperature sensor built in the inverter. When it is over 45 the fans will work automatically. When the temperature is over 75 -80 the inverter will be in protection mode till it cool down. 12V is generally for cars 24V for trucks 48V and 60V is generally for electric vehicles.
