I was disappointed by the Enphase warranty and service support program. I would expect something better than the industry standard 10 year warranty for a product like this. I would take a really strong warranty and service support agreement out to at least year 15 to inspire confidence in the product.
The customer could be sucking wind after years 13 or 15. The cost of going out and replacing failed inverters piece meal as they go thru the failure bell curve is really unsupportable. We may all be off the hook for CSI warranties but it is real trouble for the customer who has an array with a 25 year service life. If Enphase really believes that these inverters will be running fine out at year 20, they should indicate that thru the warranty. If not, folks should do some real careful life-cycle cost accounting before they go out and start selling these things. Hey, if you are delivering a system with a 10 year design life, fine. But if you are working on 25 year designs like I am, then the Enphase won't cut it without much stronger commitment to long-term performance from the vendor. :-) Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 www.berkeleysolar.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Loesch Sent: Friday, October 24, 2008 6:49 AM To: RE-wrenches Subject: [RE-wrenches] Request for Enphase inverter comments Hi Gang, For the number of ads I've seen for the product, I am surprised that there has been no discussion of the benefits/disadvantages of this micro inverter product.
