Hey Drake,
We're finding that the small systems are cheaper if you use a 72 cell module, then a simple PWM charge controller with 24v battery and the smallest 24v inverter you can find, samlex makes a 300w 24v sine wave inverter for about $160. That combo can often come in lower than using a special mppt charge controller just to deal with "bucking down" the voltage for a 12v setup. It all depends on the details though. If they're set up to run off of 12vdc direct, then adding an inverter is an extra expense, but it can still work out. You just might want to price it both ways to see what works for you with the pricing and products you have available.

From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Drake Sent: Thursday, June 19, 2014 9:31 AM To: RE-wrenches Subject: [RE-wrenches] 60 Cell & Small 12 V System Hello Wrenches, A small town wants to put a kiosk in a park with a video display. It would be great to power this with a 60 cell, 255 W module and charge a 12 V battery. Morningstar has a product that would do this, but it will only pass through 200 W. Is there a new product on the market that would be economical and not limit the module output?
