Does anyone know about what it will cost me to have an out of warranty "U" series inverter refurbished? By whom? Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 <http://www.berkeleysolar.com/> www.berkeleysolar.com

If you want to use an SMA inverter, go to the SMA website to use their excellent sizing program. Plug in the module, and your record minimum and average maximum temps for the site, and look for a current model inverter that will work. All of the "U" series inverters (except for the 700U) are discontinued models, and the "US" series are the current models. If your min temp is not below 14⁰F, it looks like you can use all 24 in one series string with the 4000US inverter, but that gets you awfully close to 600VDC (595VDC) at 14⁰F. You might want to play it safe and drop one of the modules. Unfortunately, none of the SMA inverters will operate with only 12 modules in a string (with two strings). However, a Fronius IG-3000 will, so you might want to go with that, although it has a lower efficiency.

Can he use an SMA SWR2500U inverter with the fan kit? Is there a better inverter that will use all of his modules? If you have an SWR2500U or a better inverter option for sale, please contact me off-list. Thank you very much.
