- Do I need a Modified Sine Wave Inverter or a Pure Sine Wave Inverter?
Advantages of Pure Sine Wave inverters over modified sine wave inverters:
a) Output voltage waveform is a pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity.
b) Inductive loads like microwave ovens and motors run faster, quieter, and cooler.
c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines.
d) Prevents crashes in computers, weird print out, and glitches and noise in monitors.
e) Reliably powers the following devices that will normally not work with modified sine wave inverters
- What size inverter should I buy?
Short Answer: The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool).
You should know that load is divided into resistive load and inductive load .If you need the inverter to run the resistive load (like laptop, TV, electric cooker,LED light), please choose the inverter with continuous power higher than the appliance's rated power. And it is best to use 80% of the rated power. If you use microwaves,water pumps, air conditioners and other appliances with motors or compressors ,please choose the inverter whose continuous power is 3-7 times higher than your appliances.If you want to power up a refrigerator, we suggest you use 10 times higher power inverter.
Do not power electric applianceswhich exceed 1200 watts .
