Re: [RE-wrenches] Sanyo HIT module diode issues

Yes I did Brian, with and without the diode. That's how I found what I thought was a bad diode. On Thu, Jul 6, 2017 at 4:21 PM, Brian Mehalic wrote: > Did you test the voltage of the individual cell banks in the module with > the diodes out? > > > Brian Mehalic > NABCEP

Re: [RE-wrenches] Sanyo HIT module diode issues

The diode check on a dvm is useful but may not show a diode breaking down at higher voltage. Yes lightning can open up the tabs or connecting foil inside a solar panel. It can do alot more than that! One of the best reasons for using an SPD at the array is also preventing the latent damage that

Re: [RE-wrenches] Sanyo HIT module diode issues

Hi Brian, Thanks for the info. Yes I tested the diode properly. I was concerned that I needed to test the diode under a load to get a valid test. Taiyoko On Thu, Jul 6, 2017 at 4:14 PM, Brian Mehalic wrote: > Did you use the Diode Test function on the meter? If the

Re: [RE-wrenches] Sanyo HIT module diode issues

Did you use the Diode Test function on the meter? If the diode is good you should see around 0.4-0.8 V in the forward bias, and OL in reverse. If it is bad (open) you'll get OL in both directions, and if it is shorted closed you'll get the 0.4-0.8 V reading in both directions. Shorted closed

[RE-wrenches] Sanyo HIT module diode issues

Hi Wrenches, We were installing Sanyo HIT modules back in 2006-2007 and in 2014 we had a rash of bad Sanyo modules. The modules had distinct voltages below the good modules ie 50% or 75%. Sanyo at the time (now Panasonic) indicated that it was a bad diodes from a lightning strike not covered by

Re: [RE-wrenches] Enphase installer compensation M-190's discontinued

I dumped Enphase this season for APS. Simply put, half the equipment with almost half the time to install. and a much lower cost point. If anyone is at InterSolar I suggest lighting up the Enphase reps about the M190 issue. Make some noise. Then step over to the APS booth. Christopher Chris

Re: [RE-wrenches] Enphase installer compensation M-190's discontinued

Correction - I think it started at 15 years with labor included. I don't see how they can renege on that now. In fact, they had a power guarantee, too. They would reimburse people for lost energy as a result of warranty issues. Jason On Thu, Jul 6, 2017 at 3:02 PM, Jason Szumlanski <

Re: [RE-wrenches] Enphase installer compensation M-190's discontinued

I believe that I found out for certain. I spoke to two different people at Enphase and was "assured" that I would not be compensated as of June 1, 2017 for any M-190 replacements. I told them I would be purchasing SolarEdge, not Enphase, from now on until they felt that, as I do, they were

Re: [RE-wrenches] Enphase installer compensation M-190's discontinued

This seems odd. I thought they had a 25 year warranty originally with labor compensation, then went to 15 year at some point with no labor compensation. We have lots of M190s out there that were sold with labor coverage, so this would be important to know for certain. Jason On Thu, Jul 6,

[RE-wrenches] Enphase installer compensation M-190's discontinued

Hi all, For those who have installed M-190's, Enphase has now discontinued as of June 1st any installer compensation for replacing failed microinverters with that designation. We have a system we installed in 2011 that I found out today, after replacing the three failed M-190's, that I was on

Re: [RE-wrenches] 4 Wire Delta

Hello Wrenches, I'm picking this thread back up now that more information has become available. What I learned from talking with an AEP engineer is that the issues with the delta configuration on local AEP systems is that the transformers are wye-delta. The AEP system is wye on the utility side
