Fivestar UPSB 3000w 12v Modified Sine Wave Inverter With ChargerSPECIFICATIONDescription 1:To convert 12/24V DC power in battery to AC 230V power when there is power grid failure 2: When power grid is normal,the grid power supply output through the internal bypass directly, and its charging part charges the battery at the same time.If the load current is over the inverter rated current,the current protection will work to disconnect the mains and load,then after reduce the load, press the recoverable fuse,it will work normally again. 3: Detailed LCD display, graphical interface with digital display, let users know the inverter work state intuitively Safety Caution The shell will dissipate part of heat, so please note the temperature when touch the shell This inverter is cooled by fan please use in the indoor environment with good ventilation and heat dissipation, not allowed to use in the environment with humidity,high temperature,flammable and explosive gas Connect the battery with input terminal,the polarity can not be reversed This inverter shall be connected to the battery to power the internal control circuit Although inverter can bear the peak power of 2 times of the rated power, but if with multiple appliances at the same time, like rice cooker, water heaterair conditioner and motor with very big startup peak current, may cause overload protection to cut off the current.At this time,should turned off the appliances, turn on the inverter, then turn on the appliances one by one,firstly turn on the one with highest peak current. The interval time between 2 boots should be no less than 5 seconds (cut off the input power) Not allowed to over the rated power of this inverterWhat’s in the box1 x Power-Inverter1 x Power supply cable2 x Alligator clips Product labelPower inverter with Ac Charger 12v/3000w/20aFeatures:Inverter, UPS, AVR, and -ALL IN ONE UNITDC and AC voltage digital display-USB port 5vEfficiency up to 90%CPU control technology SCM control100% aluminum alloy case for perfect coolingIntelligent large low-noise fan and bottom radiator, cooling efficiency in-creases 80%Ups (uninterrupted power supply) and smart charger function. When commercial power is available the inverter will be transferred to use battery power converted to 220vac, the transfer time is less than 10ms which is virtually unnoticeable.InputInput Voltage: DC 12V Working Voltage: DC 40-60v Input Current: 250A/125A/62.5A Charging Current: 20A/10A/5A conversion Efficiency: >90%Output Continuous Power: 3000w Peak Power: 6000w Output Voltage: AC 220V Output Current: 13.6A/27.3A Output Efficiency: 50Hz/60Hz Ups Switching Time: 6ms Wave Form: Modified Sine WaveOthersGross weight: 6kgNet Weight: 5kgInverter Size: 440 x 230 x 95mmPacking Size: 494 x 268 x 168mmCarton Size: 556 x 509 x 366mm
