Keeping exactly 60Hz isn't that critical. The real timing is being done by crystals and the clock can be set using a little GPS or even easier NTP software if you have reasonable internet access.
Are you considering staying in sync if commercial power fails? For computer loads UPSes are great, but their frequency does drift a little. For industrial applications (like EMC2 :) even if it is 'home industry' ) exact timing doesn't matter, unless you are planning on 'grid tie' your shop to the grid. Then you should look into the 'grid tie' hardware that the solar and wind folks use. They have been doing it for a long time now (10+ years) and have it down. Personally I would like to have a 'off the grid' shop. Solar for lights and light work, kick in a generator when 'real power' is needed, and as an optional battery recharger. I guess it is just the little bit of 'green geek' in me that wants that. But since I don't have a 'shop' I can dream. Practicality says that building it and tie it to the grid and just pay the bills makes the most economic sense in the short to mid-term (2 to 10 years) to me. ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
