300 Watt Power Inverter

300 Watt Power Inverter

Product name: DC to AC modified sine wave 300w inverter
Model No.: NM300-12V/24V
Working principle:Inverter is the DC power (battery, accumulator jar battery) into alternating current (usually 220v 50Hz 60Hz sine wave or modified sine wave).
In general, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of inverter bridge, control logic and filter circuit.


Modified sine wave 300Watt power inverter information

This 300W modified sine wave dc ac power inverter was latest German technology developed high quality 90% high efficiency modified wave solar inverter CE ISO RoHS E8 approved. It was made of a heat-dissipating aluminum alloy.

We devoted ourselves to manufacturing inverter many years, covering most of Europe, Southeast Asia and the South Americas market. We want to be the top one supplier of service and quality.

So in Europe we have own after-sales service technology center, for you to solve technical matter. We are expecting become your long-term partner in China.

Q1: Is the 300w modified sine wave inverter fuse external?

Yes,external fuses are actually for better replacement, only low-power inverter has. For example: 300w 400w 500w 600w modified sine wave inverter 

Q2: How to choose the right model?

Selection of power inverter can be based on your life and work to use. Such as: 150W power inverter can use a 29-inch color TV and a VCD machine.

300W power inverter can use the general power tools.

Q3:Does the 300w modified sine wave power inverter use the input power source only from the vehicle's static or operating state? 

A:The use of input power can be derived from the car running state, it can be static.

Q4: If the car in the quiescent state, can use the 300w modified sine wave power inverter to work? Where is the input power supply  available? 

A:In the quiescent state, you can use the power inverter to work, driven by electrical appliances below 150W can be directly from the cigarette lighter socket to obtain the output power, higher than 150W when using a special clip line to connect the car battery to obtain power. 

Q5: Do you have any MOQ of 300w modified sine wave inverter ?

A: We don’t have MOQ. No matter how much the order we welcome.

Q6: How is your 300w modified sine wave solar inverter after-sale service?

A: We provide 1.5 years warranty and free maintenance /replacement during warranty period.

Q7: How long will the 300w modified sine wave inverter delivery?

A: Standard products could be delivered within 15 days; customized products could be developed within 30-45days.

Q8: How does your factory do regarding quality control?

A: Every kind of our products must first pass the German technical staff of the test, in the production process we will have the initial test and comprehensive testing process.

Q9: Why you should choose us?

A: Rich experience in production and Professional technical team Both oversea and domestic market Qualified product plus compositable prices Delivery in time Sincerely services
