Description:Built-in solar controller, can charge for battery and convert DC12v to AC 220V. Multifunction control system, including automatic PV-charging, high voltage cut-off, low voltage cut-off, short circuit protection, intelligent cooling function, ect. Cooler of fan and working status are intellectually controlled by MCU, which mostly prolongs its service life and helps to save the power consumption.Features:1. -20C - +70C1. Set the converter switch to the (OFF) position, then connect the converter to the battery to ensure good contact.2. Connect the appropriate solar panel to the solar input of the converter to ensure good contact.3. Confirm that the power of the appliance used is below the nominal power. Plug the 220V plug of the appliance directly into the 220V socket on one end of the converter and ensure that the sum of the powers of the appliances connected to the two outlets is within the nominal power.4. Turn on the transfer switch, the green indicator light is on, indicating that the work is normal.5. The red indicator light is on, indicating that the converter is turned off due to over-voltage / under-voltage / overload / over-temperature.6. In many cases, because the input of the cigarette lighter is limited, the normal converter will alarm or turn off. At this time, it is normal to start the vehicle or reduce the power consumption.Specification:Condition: 100% Brand NewItem Type: Power Inverter ControllerMaterial: Aluminum AlloyColor: Blue + BlackSize: Approx. 19.5*13.5*7cm / 7.7*5.3*2.8inchWeight: Approx. 1.416kg / 49.9ozParameter:Built-in Controller: A is 12V20A, B is 24V20ARecommended Solar Panel Specifications: 100-200W 18V, 200-300W 30VExternal Battery: 12V 100AH-150AH: 24V100AH-150AHUSB Output Current: 1000MAUSB Output Voltage: 5.0+0.3VInverter Input Voltage: AC2205%Maximum Continuous Power: 600WPeak Power: 1000WNo Load Current: <0.5A, <0.3ADC input voltage: DC9.7V~15.5V; DC20V~32VOutput Frequency: 503HZConversion Efficiency: >90%High Voltage Cutoff: 15V 0.5VLow Pressure Alarm: 11.2V 0.3VLow Voltage Cutoff: 10V 0.3VOverload / Short Circuit Protection: YesOutput Waveform: Correct Sine WavePackage list:1 x Inverter1 x Manual2 x Connecting CableNotes:1.
