You might want to try one of those lights up where the inverter is and see if it flickers up there when a load at the other end is turned on...Use walkie-talkies maybe ? Are you sure it's not just surge regulation voltage response time of the inverter itself ? boB On 2/2/2014 4:01 PM

You should rent or borrow a power quality analyzer to look at the phase angles and harmonic distortion throughout the day. A scope will also help to allow you to look at the waveform of the inverter produced electricity. You need to properly identify the cause of the problem before you invest in an

Troy, You're correct in your statement about dimmers operating on a phase shift within their own circuitry. However, that isn't likely the culprit here. 1000 feet of 350 MCM would have approximately 0.65 millihenry inductance per conductor. If the conductors are widely separated in a manner t

We've got a PV system that has long lines from the inverters to the house (1000 ft or so). While the wires are properly sized (2x350MCMs), it inherently has a lot of inductance due to the line-length. What We are noticing is that dimmable LED lights flicker anytime a new load turned on, even i
