500KW Low Frequency Off Grid Pure Sine Wave Inverter

Product Description

500KW Low Frequency Off Grid Pure Sine Wave Inverter Technical Features/Our Advantages With 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 Function RS485 remote monitoring Can add AC bypass input complementary function Can built in solar charge controller or AC-DC charger Product SpecificationsDC Input DC input: 480/540/600Vdc AC Bypass Input: OptionalAC Output Rated output power: 500kw Pure sine wave AC output voltage: 110/120/220/230/240/380/400/415/440/480VAC (optional) Output phase: Single phase or Split phase or Three phase Frequency: 50hz or 60hz Power Factor: >0.95 Inverter efficiency: >94% LCD Display Voltage 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) Protections Overload 150% for 5 seconds, 120% for 35 seconds Input reverse polarity Under voltage Over voltage Output over current Short circuit Over temperature Fan cooled, Always on Short circuit: no automatic recovery.
