40000W continuous 8000W peak true pure sine wave solar power inverter, as good as grid power, power backup for home power supply.Transfer 48VDC to 110V 120VAC, 60Hz frequency, dual US outlets. Intelligent temperature control cooling fan. Earth connection for both PCB board and output. Digital LED display..Bipolar High-frequency Inverter: With two large high-frequency inductors, this inverter has function of energy storage, boosting, filtering, and EMI elimination, which can significantly improve the performance and longevity of the inverter..Stable Output: Imported high quality mosfets with strong driving capacity.Pure copper inductance, filter the wave form, ensure the true pure sine wave AC output. 2.00mm PCB allows the stronger current floating on the circuit, increase the load capacity. There is also an independent auxiliary power supply..Powerful Cooling System: The heat sink with large surface area and the 60*60mm powerful large fan are more conducive to the circulation of air and achieve the effect of rapid cooling.
