Pure sine wave inverters are very efficient and have a very accurate waveform to the true sine wave. True sine wave inverters are a little more pricey than modified sine wave inverters because of the reduced noise and their strong compatibility with certain devices, such as electric motors. This is the better option if you value silence, or want optimal performance from electric motors, such as those found in an electric water pump. A Pure Sine Wave Inverter will give you the same high quality output as your Hydro company!
Inverters can represent a significant portion of your renewable energy investment. Choosing the right inverter for your installation may well be one of the most important decisions you need to make. The bigger the inverter the more expensive initially. So you don't want to buy bigger than you need. On the other hand, an inverter that's to small will frustrate you because you'll need to limit usage.
Here are some Advantages of a Pure Sine Wave Inverter
- Output voltage wave form is pure sine wave with very low harmonic ditortion and clean power like utility-supplied electricity.
- Inductive loads like microwave ovens and motors run faster, quieter and cooler.
- Reduces audible and electric noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax and answering machines.
- Prevents crashes in computers, weird print out, and glitches and noise in monitors.
Here is a list of some devices that will normally not work with Modified Sine Wave Inverters:
- Laser Printers, Photocopiers, magneto-optical hard drives
- Certain Laptop Computers
- Some Fluorescent lights with electronic ballast
- Power tools employing "solid state" power or variable speed control
- Somer battery chargers for cordless tools
- Some new furnaces and pellet stoves with microprocessor control
- Digital clocks with radios
