50kw Hybrid off Grid Solar Inverter 450-850VDC PV and Generator Input Without Battery

Product Description

50kw Hybrid off Grid Solar Inverter 450-850VDC PV and Generator Input Without BatterySystem Introduction Off grid without battery system consist of solar panel array or wind turbine or hydro turbine generator set or others different kinds of DC power input and wide voltage off grid inverter. The solar panel or wind turbine convert solar or wind power to electrical energy, then wide voltage off grid inverter convert DC power into AC power to take the AC load, Inverter also can add AC bypass input switch, when solar or wind power is insufficient, inverter will automatically switch to AC bypass input power(AC grid or diesel generator) as backup to take load.System Features Save cost, no need battery and solar controller, make the whole system more economical.Voltage stabilizing, when utility grid power is unstable, through off grid inverter can output stable voltage and high quality pure sine wave, has functions as high precision voltage stabilizing and filtering, voltage transient response is less than 40ms.0 second seamlessly switch between DC input and AC bypass input, when solar power is insufficient, inverter will automatically 0 second switch to AC bypass input as backup.Unique anti oscillation function, when there is no AC bypass power input, inverter still can independently and stably running, wont happen turn on and off repeatedly these oscillation problems.High efficiency, with maximum power point tracking(MPPT) function, priority to use solar power, high efficiency > 94%.Durable and Long service life > 15 years.Off Grid Inverter Technical 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: 450-850VdcAC Bypass Input: OptionalAC OutputRated output power: 50kwPure 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.
