Off-Grid Inverters

Off-Grid Inverters

Looking to go off grid and power your house with a solar energy system? If you plan on using appliances and lights that use AC (alternating current) electricity you will need an inverter. Solar panels convert sunlight directly into DC electricity which is then stored in deep cycle batteries. In an off-grid solar system it’s the job of an inverter to convert the DC electricity to AC electricity.

Video: How to select an Off Grid Inverter

We offer a wide variety of off-grid inverters from modified sine wave inverters that are best for simple systems to pure sine wave inverters that necessary for electronics and inductive loads. And we have huge selection of sizes from 100 Watts all the way up to 7000 Watt off-grid inverters.

What's the difference between a modified and pure sine wave off-grid inverter? Read more below or check out the inverter section of our series on going off-grid.

Off-Grid Modified Sine Wave Inverters

  • Best for simplest systems
  • Typically inexpensive
  • Fine for older TVs, incandescent lights, motors with brushes
  • Generally not good with: electronics, audio, induction motors, rechargeable batteries or digital clocks

Modified sine wave off-grid inverters are a perfect choice if you are putting together a DIY emergency solar kit or for a cabin with modest electrical needs. Any more modern electronic loads like a HD television or something with a high electrical surge likely aren’t good choices for modified sine wave inverters.

Off-Grid Pure Sine Wave Inverters

  • Preferred for off-grid homes or larger solar systems
  • Generally more expensive (but prices continue to fall)
  • Necessary for electronics, florescent lights and dimmers, inductive loads to operate at their best
  • Mandatory for grid-tied systems

Pure sine wave inverters work in nearly all types of off-grid solar systems, depending on the requirements of the system of course. Generally pure sine wave inverters are used in larger off-grid solar systems, but they are also for appropriate for smaller systems—like mobile applications. One important requirement to determine when trying to identify an inverter is the types of loads it will be powering.

If you are going to be powering sophisticated electronics, like a fancy new television or gaming console, a pure sine wave inverter is the way to go. Pure sine wave inverters come in all sizes (from 100W on up to over 7000W) and can be stacked to accommodate larger loads in more complex off-grid solar systems—no matter if you have a 12V, 24V or 48V system. The technology behind pure sine wave inverters is innovating continually and they are becoming more versatile, lightweight and coming with increasing programmable options.

Xantrex PROwatt Pure Sine Wave Off-grid Inverter

Check out a pure sine wave off-grid inverter in action as we outline the specs and features of the Xantrex PROwatt pure sine wave 12V inverter that’s perfect for a smaller mobile application. The Xantrex PROwatt works great in mobile applications like a boat or mobile home—and is available in versions for North America (120V/60Hz) and International (230/50Hz). Watch to learn more!
