Will Inverters Compete With Storage? Will They Take Over the Grid? via @greentechmedia

SAN FRANCISCO --- Who needs energy storage when you have a smart inverter? Battery banks and other energy storage technologies essentially absorb power produced by solar panels and wind farms and distribute it to the grid in a smooth, orderly fashion. Smart inverters, meanwhile, convert DC power from panels and turbines and then deliver it to the grid in a smooth, orderly fashion through the magic of networking and communications. In other words, the process is the same, but the smart inverter is probably cheaper. "An inverter can act like a capacitor," said Owen Schelenz, an lead engineer at General Electric, speaking at a solar electronics symposium at Intersolar in San Francisco this week. "Energy storage is still unproven technology. Should it be at a photovoltaic power plant or a substation?" Inverters can also ameliorate voltage dips and spikes to stabilize the grid,...
