Summary

In recent years inverter technology has become more prevalent as the demand for backup systems has been on the rise. The two prevailing technologies are modified sine wave and pure sine wave inverters.

What is a pure sine wave inverter?

As the name suggests a pure sine wave inverter outputs voltage in a sine wave. If the inverter is to be grid tied it needs to be a pure sine wave inverter because utilities provide an AC signal output supply. These signals need to match up in frequency if the Inverter is ties to the grid.

What is a modified sine wave inverter?

A modified sine wave inverter produces an AC output by rapidly switching polarities from positive to negative, producing a square waveform akin to a stair pattern.

Comparison between inverters

Modified sine wave inverters generally remain the cheaper option of the two mentioned above. There are, however, several disadvantages when using a modifies sine wave inverter. Modified sine wave inverters are less efficient on average than pure sine wave inverters. This is due to the rapid switching between positive and negative. Another problem caused by this rapid switching is that sensitive electronics and motors cannot run on a modified sine wave signal. Modified sine wave inverters can also not be tied to the grid. As a pure backup system, a modified sine wave inverter can be used if the load is taken into consideration. Pure sine wave inverters make up for a lot of these disadvantages; pure sine wave inverters can be tied to the grid, they can run motors and sensitive electronic equipment and they run more efficiently on average than the modified sine wave counterparts. All this is at the expense of cost.

In conclusion

While modified sine wave inverters are currently cheaper than pure sine wave inverters, pure sine wave inverters are becoming steadily cheaper as demand for them increase and as the technology improves. Whatever inverter you choose to purchase REVOV Batteries can offer a solution for your needs as REVOV batteries can be used with either a modified sine wave inverter or a pure sine wave inverter.
