How to select solar inverter for your RV off grid system
10 Mar 2022

Inverters are the final, crucial component to consider when piecing together your solar installation. Inverters turn DC power produced from your solar panels and stored in your battery into AC power. An inverter is necessary to power the common appliances found in your home or RV, from TV’s to microwaves. When shopping around for inverters, you’ll quickly learn there is not a one-size-fits-all approach.

There are two main inverter types: pure sine wave and modified sine wave inverters.

Pure sine wave inverters are capable of producing smooth, quiet, and reliable electricity to operate appliances and electronics without any interference. Like its name suggests, pure sine wave inverters produce current in a pure sine wave shape. EverExceed sells a range of pure sine wave inverters of varying capacities to fit your solar installation and your energy needs. EverExceed inverters also provide overload protection for both DC input and AC output to prevent damage to the components and the unit.

When looking at the waveform from a modified sine wave inverter, it has a stair-step, square pattern, where the polarity is flipped back and forth. Because of the choppiness of the wave pattern, modified sine wave inverters can negatively affect more delicate, sensitive equipment. If you have medical equipment you need to power, such as a CPAP machine, we recommend using a pure sine wave inverter. In many cases, you’ll hear a hum with devices attached to a modified sine wave inverter.

What can I run with a modified sine wave inverter?

Modified sine wave inverters can be used in simple systems without sensitive electronics. If you’re running an appliance that does not have an AC motor and isn’t a delicate piece of medical equipment, you may be fine with a modified sine wave inverter. Old tube TVs, water pumps, and phone chargers usually operate ok with a modified sine wave inverter.

Appliances like refrigerators, microwaves, and compressors that use AC motors won’t run as efficiently on a modified sine wave inverter. Some fluorescent lights will also not operate quite as bright, and some may buzz or make humming noises.
