1、Stable Output: Power frequency low loss loop transformer, pure sine wave output, sine wave waveform is as good as that generated by the power grid or generator. 2、Reliable Work: The inverter supports the input and charging of mains power and gasoline generator, and can work normally in harsh power environment. 3、Practical Use: The factory default of the inverter is the battery parameters. The user can set the charging and discharging parameters of other types of batteries through the operation panel. 4、Working Modes: Mains power first, inverter first, and energy saving mode. Automatic switching of working mode, switching time ≤ 4ms, the computer will not shut down within 4ms. 5、Simple Usages: When the inverter fails, the fault coding will be displayed on the display screen, which is convenient for users to self check and self repair. 1 x Solar Inverter2 x Connecting Cable6 x Screw1 x Bracket1 x User Manual Item Type: Solar InverterRated Power: 1500WMachine Size: Approx. 500 x 300 x 140mm / 19.69 x 11.81 x 5.51inInstallation Mode: Wall MountedInput:DC Input Voltage Range: 10.5-15V DC, single battery voltage.Mains Input Voltage Range: 170V AC-275V AC.Mains Input Frequency Range: 45Hz-65Hz.Maximum Mains Charging Current: 0-30A, depending on the model.Mains Charging Mode: 3 stage of constant current, constant voltage, and floating charge.Output:Inverter Output Efficiency: ≥ 85%.Inverter Output Voltage: 220V AC ± 2%.Inverter Output Frequency: 50/60Hz ± 1%.
