I'm unable to find any detailed information on the output power of the MultiPlus with regards to its cleanliness and sine wave stability. What kind of sine wave does it output, and is this unit suitable for electrical equipment such as speakers for instance. Any info would be appreciated.
It is s true sine wave inverter, tried it on an oscilloscope at work. Even under load it is stable.
My husband is a bit of a sound enthusiast, has built his own amplifiers with studio monitors from a recording studio. Best sound from he amps built is when we disconnect from grid power and let the Victron determine the power quality.
There is no hum or other whining sound heard (if there are no issues with the amps or cables themselves).
Thanks Alexandra, this is good info to hear. I had one of these units installed in my studio, and tech here at Victron also confirmed a <2% THD value for the output. I'd love to know more about how this sine wave is formed. Is it stepped, and then smoothed? Not a lot of info on the website though.
Sadly, I was under the impression that the current always passes through the inverter, however have now discovered it passes grid power through the inverter untouched between + & - limits, so I'll need to review the situation and install additional power conditioners.
It uses the PWM sinewave technique.
