Re: [RE-wrenches] TR Inverter Problems

[Allan Sindelar]

Ray, As I prefer sine waveform, I haven't built a system with a DR in ten years and have never used a TR. However, we just installed a modern system for the new owner of a home that had previously run a TR1512 for years. The old system - which was seriously non-Code funky - showed none of those symptoms. Sure, it had fried the customer's MacBook, but at least the voltage was stable. Could it be a combination of a defective unit and a clueless tech support newbie? "Switch to incandescents?" That's a new one, good for the record books. My BS detector just went off the scale... Can you ask "to speak to your supervisor" and get a warranty replacement to try?

We fixed numerous wiring issues, including neutral bonded to ground in 7 different places! The issue we're having now though, is that the TR inverter output voltage fluctuates when running CF lighting, and the refrigerator. You can literally see the lights cycling brighter and dimmer, and hear the compressor on the fridge running up and down in frequency. Xantrex/ Schneider Tech support said that: A) The TR doesn't do well with CF lighting, and that we should switch to all incandescent........ hmmmm. B)  We should set the search watts to zero (which I already did) C) We need to increase the loads on the TR, as it doesn't regulate output voltage and frequency very well at lower loads........ 2nd big hmmmmm. I knew there was a reason I quit installing Xantrex inverters about 5 years ago, but I couldn't recall the details.  Now its all coming back to my feeble, aging brain.  So aside from switching out the inverter , (which I just installed on a beautiful Midnite E-Panel) does anybody have any cures for our ills?  How would LED lighting behave?  Should I throw a capacitor across the output?  or perhaps I should just retire early and sail around the Caribbean? (I can afford a canoe/ no sail......) As always, thanks in advance for this wonderful technical (and emotional) support group,
