This is a 2160 watt Grid Tie with Battery Back-up system in Pembroke Pines, Florida. It was installed to back up their home office and to provide back-up for some additional medical equipment.

We used 12 Evergreen ES-180 panels and fed an Outback Flexmax 60 charge controller and a GVFX3648 inverter in a Flex 250 configuration because of the limited space. The customer added a Sundanzer refigerator and freezer for additonal reassurance for when the utility might be down. The batteries were not permitted by the local jurisdiction to be in the garage, so they had to be located outside. We provided them in a vented dockbox that contained 11,760 watt hours of auxilliary battery back-up.
