Sonnen’s Home Energy Storage System Yields RMR from ‘Virtual Power Plants’
It’s been a while since custom integrators could get “energized” about a new equipment category. But residential energy storage could "spark" a whole new wave of enthusiasm, along with high profits and recurring monthly revenue (RMR), among integrators. The newest entrant into the space is sonnen, a 10-year-old Germany-based maker of high-end residential energy storage systems. The company’s technology is widespread in Europe, serving nearly 30,000 homes.
