The Powerwall is an electricity storage device that detects power outages and automatically becomes your home’s power source on one phase when the grid goes out. Unlike generators, the Powerwall keeps lights on and keeps your phone charging — with no fuel consumption or noise, and no separate startups either. Combine your Powerwall with a single-phase inverter to be able to recharge solar energy even in the event of a power failure. The inverter is the technologically most important component of any solar power system: it converts the direct current generated in the photovoltaic cells into alternating current that is compatible with the grid. As an intelligent system manager, he is also responsible for yield monitoring and grid management. Solar inverters are characterized by a particularly high degree of efficiency. The Sunny Mini Central from SMA already offers an efficiency of over 98% and thus enables increased electricity production.
