Re: [RE-wrenches] Enphase / Inverter failures

Corey, Thanks for sharing this helpful information. I decided to test M190s on my shop in early 2010 before offering a new product. Until about 8 months ago, when we started seeing engineers specify Enphase, I refused to install more of the units. My breakdown in Midwest climes: - M190 - 9/15

We still have clients who are patiently waiting for sma's 240. Perhaps their commitment to battery based inverters will assure that it will also be supported into power when the grid is down. And while it should be good when it's out, at one their road shows they were still passing around a mock

Larry, Interesting. Might be that whichever tech at Fronius handled your call totally dropped the ball. Might be that the squeaky wheel gets the grease. Either way, score one for the Wrenches list! Good deal. Bob-O On May 9, 2013, at 4:15 PM, Larry Crutcher, Starlight Solar Power Systems wrote:

Larry, I have only replaced a few Fronius inverters, but in those cases, they sent a check without being asked. John Blittersdorf NABCEP Certified Solar PV Installer tm Central Vermont Solar & Wind LLC 104 River Street Rutland, VT 05701 802-770-8625 Cell 802-747-0577 Office 802-773-0924

[RE-wrenches] not sure what's going on here

2013-05-10 Thread Ron @ earthRight Solar
Hi Wrenches, Wondering if anyone can shed some light on this. I have a customer who self installed 4 x 165w Solarworld panels a few years ago (2008). It's a 12v nom. battery and the panels are wired in parallel. They've been working fine for five years on a full time household using a 3024i Bl

Hi Ron, The problem you describe is due to the firmware in very early versions of the 3024i. What would happen is once you hit the 30 amp current limiter, the controller will switch the input to act like it is connected to a nominal 12 volt module, lowering the input voltage. Contact Blue Sky f

Ron, It certainly sounds like a failed diode (there are two) to me. Usually they fail open, but it isn't unheard of that they might just avalanche when they see the current of the other PVs. Solarworld would probably replace it under warranty IF you return the dead module to them. How the hell d

I'd echo Bob-O on this and also add that when diagnosing others' work over the phone, it often is completely different issues when you get there. You have no idea if for instance he's actually got the modules wired correctly, he may have a loose connection(s) there, the parallels may all be lo
