Battery Storage
You can install some battery storage in your house (to become more self-sufficient), charge your electric vehicle or combine several households in an area into a microgrid. The old style lead-acid batteries are high-maintenance, complicated to set-up, bulky, need ventilation and are not pretty to look at. New storage options have been developed (US Tesla Powerwall and Enphase Home Energy Solution with lithion-ion batteries) that allow you to more easily become more self-sufficient. You could perhaps compare the Tesla batteries to the iPod, where before there were mp3 players – basically this product is just a lot better than what what was offered before, and cheaper! Prices start from approximately NZ $5,000 (including GST and freight). The first units are expected to arrive sometime in NZ in early/mid 2016.
Super capacitors
MyPowerStation is a roll-in solution that features everything required to add a storage system to a new or existing solar array. It is fully adaptable in a range of sizes. From households to institutions.
Sirius is a revolutionary product that stores energy using supercapacitors, rather than through a chemical composition. It is safer, and more efficient than any alternatives. Can be added to any existing system – micro or string inverters.
