Old is the New New

Our old inverter is now our new inverter

So it’s early afternoon. We’re chillin’ in the RV . . . I’m computing, Jan’s reading one of The Expanse books.

Then we hear a very loud noise that sounds as if one of our air conditioners fell off the roof. (BTW, that’s not what happened.)

It was the sound of our generator starting up. This happens when the voltage in our batteries drops precipitously. And that’s just what happened.

Our inverter/charger failed — well, the battery charger half crapped out.

So for maybe an hour or so we were running off our batteries and drawing them down, down, down until our AGS (Automatic Generator Starter) kicked in and fired up the generator. Voila!

Thank god I kept our old inverter . . . a venerable and dependable Heart Freedom circa 2001.

Two hours later I had pulled out the Magnum MS2000 and installed the Freedom. For the nerds, I also had the swap out Magnum’s high-tech ME-ARC control panel with the Freedom’s basic remote control. Easy peasy as both remotes are the same size and connect to the inverter via a phone line.

A new Magnum is on order because it’s a Pure Sine Wave (PSW) inverter while the Freedom is a Modified Sine Wave (MSW). Basically, the difference between a PSW and MSW inverters is that a PSW is gentler on electronics.

New Magnum will be here in a few days. Oh joy.

This is the 3rd time I’ve done this inverter swap

  2. Sorry to hear of your failure. I also have a Magnum MS2000 invertor charger , it only powers our residental fridge since 2009. Problem free so far. Is this the second failure for you?

    • It’s the 2nd failure for the same MS2000. The first time it failed was during its warranty period. Magnum refurbished it. So a brand new MS2000 this time.
