Supercap's (SC or CAPS) have very high energy delivery, however unless individual Cells are configured into multiple/large banks, individually Cells provide little energy storage for residential or commercial Micro Grids.
With manufacturers now building large Dry-cell Graphene SC modules, the future of Energy Storage will transition towards this trend, until a better technology come along.
Elon Musk (TESLA) purchased Maxwell, one of the largest SC manufactures, that in itself indicates the future of Energy Storage for Vehicles, Residential, Industrial and Remote locations, is the future of energy storage!
SC modules are able to be fully charged in 10~60 minutes, No other energy storage Technology can provide that and SC have a projected 20'000~50'000 Cycle life.
Super Capacitors (SC) Modules can be configured in single, two or three phase power, and used as the primary energy storage. SC Modules simply Plug into the Hybrid Inverters and SC can be Charges on LAB Charge cycle, DC input to Maximum 450V DC in some cases.
Unlike any other Energy storage technology, Super Capacitors can be Charged in 10~30 minutes, SC Modules have an estimated 25'000~50'000 Cycle life, depending on the SC cell type.
