Inverters play a vital role in your solar power system as they convert the direct current (DC) produced by your solar panels, into usable alternating current (AC) power, which is important because most appliances and devices run on AC power. Deciding on the type of inverter to get can be tricky, so we’ve outlined some of the differences between the two common types below along with our suggestion on which one you should choose.

Modified Sine Wave Inverters. This is an extremely common type of inverter that many use for running common resistive loads such as lights and appliances due to its reliability and cost-effectiveness. Another benefit is that modified sine wave inverters are less prone to fluctuation in their power delivery. However, they do tend to have some drawbacks as well. For starters, modified sine wave inverters produce up to 30% less power output compared to a pure sine wave inverter, resulting in a reduced lifespan due to excessive heat build-up.

Pure Sine Wave Inverter. A pure sine wave inverter operates in the same manner as a modified sine wave inverter, by converting DC to AC. The key difference is that it conducts the power transformation at a quieter, faster, and more consistent rate, resulting in interference-free power. Added benefits include an increased efficiency rating, consistent power delivery, and minimal risk to your appliances/devices. Although the initial cost of a pure sine wave inverter might be on the higher end, it will end up becoming a return on your investment in the long run.

So, which option should you choose?

While modified sine wave inverters have their place in solar setups, we recommend choosing a Pure Sine Wave Inverter. They are ideal for running any load within their wattage range while still being quiet, efficient, and effective at converting DC power to usable AC power.

If you’d like to get one of your very own Pure Sine Wave Inverters, we carry both 1200W and 2000W options. You can even buy them in a kit, where you’ll receive all the brackets, hardware, wiring, as well as a remote control, all in one.
