Wrenches, Since my previous post (see below) we have recovered the faulty modules and are now looking to replace the diodes in order to make them functional again. I have had no success sourcing replacement diodes from the original module manufacturer, Mage Solar.
Can anyone recommend a source for replacement diodes? -- Corey Shalanski Joule Solar New Orleans, LA ᐧ On Tue, Aug 5, 2014 at 10:27 AM, <[email protected]> wrote: > > Message: 10 > Date: Tue, 5 Aug 2014 09:03:09 -0500 > From: Corey Shalanski <[email protected]> > To: [email protected] > Subject: [RE-wrenches] Diode Failure > Message-ID: > < > ca+smqz1c7kszuqnvzqr0mmux3f2dt6ydum40iseczr2ejrg...@mail.gmail.com> > Content-Type: text/plain; charset="utf-8" > > Wrenches, > > We recently were contacted by a customer who reported a lightning strike > close to his house.
