The MSI Range from Marshall are high quality inverters with a warranty starting from 1 year. Whether you are living off grid full time or just trying to make a cup of tea, our inverters are with you all the way!
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. To do that, it must take the constant DC voltage and change it to a sine wave curve that goes 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 modified sine wave. More advanced modified sine waves (MSI) make multiple steps, trying to come close to a pure sine wave inverter (PSI)
A modified sine wave inverter can be used for simple systems that don’t have any delicate electronics or audio equipment that may pick up the choppy wave and produce a hum. Old tube TVs and motors with brushes are usually ok with modified sine wave. Some equipment may seem to be working fine, but may run hotter than with a pure sine wave and reduce the life of it.
