400KW Low Frequency Off Grid Pure Sine Wave Inverter

Product Description

400KW Low Frequency Off Grid Pure Sine Wave InverterTechnical Features/Our AdvantagesWith low frequency transformer, 100% full power output, can work 24hx7.High efficiency > 94%, low loss and long service life > 15 years.Mitsubishi IPM intelligent modular structure design, easy and low cost for futures maintenance, powerful protection for over load, short circuit, over temperature which is more safe and reliable.The DC input voltge range, output voltage, output frequency can be set.Two kinds of start mode: variable frequency start or step down voltage start, higher capacity to drive inductive load.AC bypass input(DC power priority or AC bypass power priority can be set) and RS485 monitoring optional.Wide voltage input range can be selected from 100-400VDC or 200-600VDC or 400-800VDC, off grid inverter can work without battery.Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.Approved by European CE (EMC, LVD, UL1741, CSA22.2) certificate.Optional FunctionRS485 remote monitoringCan add AC bypass input complementary functionCan built in solar charge controller or AC-DC chargerProduct SpecificationsDC InputDC input: 480/540/600VdcAC Bypass Input: OptionalAC OutputRated output power: 400kwPure sine waveAC output voltage: 110/120/220/230/240/380/400/415/440/480VAC (optional)Output phase: Single phase or Split phase or Three phaseFrequency: 50hz or 60hzPower Factor: >0.95Inverter efficiency: >94%LCD DisplayVoltage accuracy: Load balancing<1%, Unbalance <5%THD: linear load, 2%, nonlinear load >3%No load amps: 2% of inverter size depending on DC voltage (1000 watts / DC input voltage = amps)ProtectionsOverload 150% for 5 seconds, 120% for 35 secondsInput reverse polarityUnder voltageOver voltageOutput over currentShort circuitOver temperatureFan cooled, Always onShort circuit: no automatic recovery.
