It would seem to me that a properly designed off-grid system with a properly engineered battery (or other) back-up subsystem would provide a continuous source of power. One may need to do a load calc to show that the PV system (under a suitable worst case scenario) can indeed provide the 24 hour load requirements.

Once it passed they officially could move in. Richard _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Yago Sent: Friday, November 14, 2008 1:14 PM To: [EMAIL PROTECTED]; RE-wrenches Subject: Re: [RE-wrenches] permit denined since no grid connection Thank goodness this was not my project, but I just received a call from a couple that had purchased an old farm house in a rural part of the state that was almost a mile from utility lines and never had power. They are renovating the old farmhouse and applied for all permits from county and have no problem with having inspections. However, the electrical permit was denied on the basis there was "no contineous source of power and this would not be classified as a weekend type cabin". Yes, I guess its possible a local county can make up their own rules, but I am not aware of any requirement in the NEC, and if there is a specific rule, I would think all they would need to do is provide information on their proposed generator/solar/battery/inverter system. We have never had any problems like this in any other counties we have systems, but before I advise them on how to proceed I wanted to make sure that there were no specific code requirements other than the electrical inspection. Have you run into this before? Thanks, Jeff Yagoi _____ Netscape. Just the Net You Need. The information contained in this message may be confidential and is for the intended addressee only.
