Review: Magnum MS Series Inverter

For a comparison, see Inverter comparison: Magnum MS series vs Outback VFX series.

If there is one word that could summarize the Magnum MS series inverters, it would be "simplicity".  That can be a good thing as long as its not so simple and automatic that necessary customizations are impossible.  I think Magnum has done a good job of balancing this simplicity with their MS Series inverter.  Initial programming took all of about 5 or 10 minutes but yet I can adjust or customize the items I really need to.  While I personally don't mind dealing with a lot of options, this could be a real blessing to some.

Installation

Installation of the inverter was straightforward and fairly easy.  Any time you are dealing with heavy gauge wire in tight places it can be a challenge. However, the Magnum has easy access provided that made the job much easier than some! I had to be a bit careful during installation not to dent the aluminum case, but once the unit is bolted into place, this really is a non-issue.

Quiet is NICE!

The single most impressive feature for me was how quiet this inverter is!  After living with the noisy Outback and an even noisier Xantrex, this is a delight!  The level of sound is so low I literally have be less than 5 feet from the unit to hear whether it is operating or not.  And since our inverter is mounted in the pantry/power room, rather than in an outbuilding, this is a very nice feature indeed.

I was slightly disappointed with the RC-50 remote. It seemed to have a flimsy plastic feel. I do like the rotary knob because it does speed up and ease the use since it is plastic.  Magnum also sells the ARC-50 which has more options available and is recommended if you intend to use the automatic generator start (AGS) feature, so it is possible that it is built with higher quality materials.  But so far, I have encountered no problems with the RC-50.

USA Made

The other item that I really appreciated is that Magnum products are still made here in the USA. Something to be said for that!  And with this inverter selling at a competitive price ($1,800-1,900), I think it's a great choice for anyone looking for an easy to use, good quality sine wave inverter.

As I discover any additional pros or cons, I'll try to keep this updated. So be sure and subscribe to this post if you are interested in that.
