What is the Difference Between a Modified Sine Wave And a Pure Sine Wave Output?

The primary job of an inverter is to convert the DC (Direct Current) power from the battery bank or solar panels to AC (Alternating Current) power needed for most appliances. It must take the constant DC voltage and change it to a sine wave curve above and below 0 volts.

When inverters first came out, the most common way to do this was to make the voltage go straight up and down, creating a blocky signal. This is called a modified sine wave, seen in orange in the image below. More advanced modified sine waves make multiple steps to come close to a pure sine wave.

Will a Modified Sine Wave Affect My Device's Performance or Damage My Device?

If the device you want to power uses a rectifier to change the AC into DC (A power brick), it's extremely unlikely that you'll have any issues. That means your laptop is going to be fine.

The full list of electronics that work just fine with a modified sine wave is far too long to get into here. Suffice it to say that if it doesn't use an AC motor and isn't a delicate piece of medical equipment, you will be in the clear.

When I Use My Multimeter to Test the AC Output, the Reading is Not 110V and Is Jumping Around. Why Would This Happen?

If you are trying to measure Modified Sine Wave output with a multimeter that is not rated "True RMS multimeter," this would happen. It does not mean that AC output is malfunctional. For more details, please refer to the following YouTube video.

Solar Panel FAQs

Solar Panel Ratings And Efficiency Explained

Rated Output / Power Output Capacity. This is the amount of power a solar panel can generate. Power is measured in watts (W) or kilowatts (kwh). A 100W solar panel can produce 100W per hour under ideal weather conditions, a 300W solar can produce 300 watts an hour and so on.

Efficiency. The efficiency rating measures the amount of energy the panel is converting into energy. Most solar panels have an efficiency rating between 17%-23%. A solar panel with a 21% efficiency rating means it converts 21% of the sun’s energy striking it into electricity.

Do not confuse the efficiency rating with the rated output. A 23% efficiency rating does not mean the panel will only produce 23% of its rated output in watts.

What Happens to a Solar Panel When the Battery is at Full Capacity?

When a solar panel battery is at full capacity, it simply becomes 100% charged. The built-in battery management system will ensure no fire concerns arise if it uses modern lithium batteries.

When the battery bank becomes full, it stops absorbing power from the solar system. The solar panels will continue to generate a voltage that will not be used or stored unless there is an energy demand or more battery space.

Can a Solar Panel be Left Disconnected?

Yes, a solar panel can be left disconnected since there is nowhere for the voltage to go when the sunlight strikes the surface. The panels' temperature may increase, but the panels are large enough that this heat will not affect the solar panels.

How Long Do Solar Panels Last?

Solar panels are made to last more than 25 years. However, solar panel life expectancy doesn't mean constant electricity production - energy production will decrease over the years, but their lifespan remains remarkable.
