August: What about the expense of servicing and/or replacing roof mounted inverters? There is a very finite limit on the weight that is practical/legal to haul up a ladder. Sure it's easy to toss an inverter on the roof at the install when there is already a lift in the budget to hoist the PV. Later on your crew might be tempted to slide a replacement inverter up the ladder, but this is not always safe or OSHA legal. It's at least $400 to bring a scissors lift and a reach lift is about $600. Is this really good economics / safety practice?

Going forward, we are going to strive to put inverters on the roof to minimize the expense of dealing with the 1000 V runs. _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
