Unstable power grids, planned shutdown of electrical power, or even blackouts: How can we prepare our homes and home automation systems against such events? Today we will cover these topics with the eyes of an engineer, and I will show how I protect our home against short and longer outages.
In part one we protected our homes against short outages. Today, we will protect them against longer outages. I will focus on my PV, but also show how you could use an ordinary emergency generator.
