1. How does a power inverter work?
A power inverter converts DC power into conventional AC power, when an AC outlet is not available. Simply connect an inverter to a battery source, plug your appliance into the inverter. 2.What is the difference between PWM inverter and MPPT inverter?
PWM is Pulse width modulation, it is a old solar power controller technology, its efficiency is about 70%. MPPT is Maximum PowerPoint Tracking, it is the latest technology. it contains Low Voltage and High Voltage, 2 types. High voltage inverter efficiency up to 95%.
3.How to distinguish Low voltage and high voltage inverter ?
Low voltage, Max PV voltage Voc 150V. High voltage, Max PV voltage Voc 450V
4. What is the difference between a modified sine inverter and pure sine wave inverter?
Modified sine wave power inverter is more portable than pure sine wave power inverter, lighter, and lower in cost. If the device handles voltage fluctuations, a modified sine wave inverter should be considered.Most devices that people typically wish to power will work fine with a modified sine wave inverter.
Pure sine wave power inverter allows motors to run cooler, last longer and provide very clean power that is same quality with State Grid. Devices such as air conditioner, freezer and most medical equipment require a pure sine wave inverter to run.
5. What type of batteries do you recommend?
Most of people choose to use deep cycle marine batteries with their inverters. Also can use Acid battery, Lithium battery.
6. Do you accept OEM and ODM service?
Yes, we accept OEM and ODM service.
7. How long of the delivery time, sample order and wholesale order?
For Sample order, within 7 days; For 100pcs wholesale order, 7-15 working days.
8. How do I know which inverter to buy?
Different devices require specific wattage to run. Please check the following formula to determine the correct watt model.
