Jesse,
There's little advantage to 24V over 48V; as you're in the design/bidding stage, can you use 48V instead? Then one FM60 (or Midnite Classic) is all you need. 48V also lets you use 175A GJ-type breakers, 2/0 cables, and 1 1/2" conduit to the battery enclosure. One of the few limitations is that with modern 60-cell modules, you must use 3 in series - no more, no less - with Outback controllers. Otherwise I agree with Ray that two controllers makes more sense. Allan

Hello, I'm working on bid for a system using the FM80 controller. The specs for the controller say the maximum STC wattage for a 24V system is 2500W. The array I want to use has a STC wattage 2550. I called outback to ask if this was "close enough" today and didn't get a reply (holiday weekend?!) I also called the distributor I buy my parts through and they said it wouldn't be a problem.I don't want to lose warranty of something happens. I don't want to use different modules. I don't want to have to add another controller and split up the array just for 50W. Thoughts? Have a good holiday weekend!
