The DC to AC Power Inverter Converts 24V DC power from external battery to 110VAC 120VAC Power for AC appliances, Full power of 3000W Rated Power,6000W Surge Power. Solid true sine wave inverter, safeguard your electronics and suitable for sensitive equipments like medicine machine,testing machine ect.. With a harmonic distortion below 3% and a peak efficiency 0f 90%,this inverter produces a clean electrical wave without an eccessive amount of heat .Equavalent design of heat radiation sink and intelligent cooling fans. The 3000W power inverter is enough for normal use in a home power supply such as TV, Lights, Washing machine, kettle, kitchen machines, such as coffee maker, kettle, cooker, Oven, microwave, ice machine, fridge ect and also A/C air conditoner, Heater ect. Good use for office use of computer, printer projector ect. Suitable for sensitive testing machine, emergency medicine equipments and any other off grid power application. Low no load current draw of under 1A,the power inverter will drain you battery much slower than many other kinds of inverter.Wide DC and AC voltage ranges.Friendly with most kinds of batteries. All big branded mosfets with strong driving capacity. High quality true copper inductance filters the wave form, ensures the true pure sine wave AC output, safeguards your equipment. WZRELB owns the exclusive technology of the pure sine wave dc to ac power conversion. With the most advanced software and hardware design, reliable inverter can ensure the reliable performance. The PCB thickness is 2.00mm, which allows the stronger current floating on the circuit, increase the load capacity. High frequency transformer to transfer DC to AC, ensure the stable and full AC output. During use, due to the influence of the load, the output voltage may be too high or too low.Pls kindly known that the output voltage can be reset in a certain range at your end
