Technical FAQs 4

Should you use a pure sine wave inverter?

With a pure sine wave inverter, you can safely run and charge: Pure sine wave inverters produce stable power with low harmonic distortion you can safely use with medical equipment. Such clean power output buys you peace of mind knowing that your expensive devices are safe from power disruptions.

How do I choose a sine wave inverter?

When selecting a sine wave inverter, it’s crucial to consider the power requirements of your appliances and the energy source. A power output rating that matches your total power requirement, coupled with the right input voltage for your DC source, will ensure a reliable and efficient system.

Is a modified sine wave inverter enough?

A modified sine-wave inverter might be enough if you need basic backup power for lights and tools and want to keep costs down. As solar technology becomes more affordable, pure sine wave inverters are becoming the go-to choice for most off-grid users. They’re quieter, more efficient, and safer for your devices.

How much power does a sine wave inverter use?

A 15 cu. ft. fridge uses 105 watts an hour with a pure sine wave inverter, making the total daily consumption 840 watts. With a modified sine wave inverter, the power consumption is 120 watts, resulting in a daily consumption of 960 watts. Some modified sine wave inverters have even lower efficiency ratings than that.
