Re: [RE-wrenches] Tech Support Issues with Sensata

[Ray Walters via RE-wrenches]

Those voltage and frequency variations are way out.  No need for THD 
readings.  You can't reliably run a household with that much variation, 
it will start letting the magic smoke out of many of the appliances.  
I'm not sure about a bad relay, I don't see how that would cause that 
variation.  That sounds more like a cooked control board.  I had 
lightning damage cause an inverter to put out 140 vac, while its onboard 
electronics read 120 vac.


If it helps, I have a used MS 4024 PAE (very low hours) that I could 
send to you.   Contact me off list if you want.

I agree, a THD would be a good next step.

What were the issues?  I've not seen a Magnum have power
quality troubles, but they are not the "grid" either.  My
experience is that they are similar or a bit better than
Outback, but certainly have measurable THD in the 4 to 5%
range.  Its almost always finicky loads, and the inverter has
always been within its tolerances, so I doubt you have an
actual warranty issue.  However, I have seen inverter output
get strange after lightning damage, which is not covered under
warranty either.

You need a decent meter that can measure THD, and can capture
the peak voltage of the waveform.  A good oscilloscope is even
better, so you can see the waveform.

Stuff like clocks not keeping time, or certain digital
controls on certain appliances not functioning, is not a
warranty claim. Lights dimming, or LEDs flickering is not a
warranty claim.  These are normal living off grid, and the
only thing better than a Magnum for power quality is Exeltech
in my experience.

[RE-wrenches] Tech Support Issues with Sensata

[Chris Sparadeo via RE-wrenches]

Hi all,

I have a client with a Magnum MS 4024- PAE inverter. There are some serious
issues with power output quality and according to the client, another
installer had started the RMA process while the inverter was still under
warranty, however Sensata has not been responsive and has lost track of the
case. They are asking for a new case to be initiated, but the inverter is
now out of warranty. Has anyone out there had similar lack luster support
issues with Sensata?

Best,

Chris
