One way to make the apartment follow the cheapest electricity prices on the exchange is to use smart electrical plugs. These electrical plugs connect the apartment's electricity consumption to the spot market and allow the apartment's consumer to buy electricity at the lowest prices. They also react to these changes in market prices and prevent over-consumption of energy.
Another option is to connect your apartment to the electricity network in a way that allows you to connect and disconnect your apartment from the purchased electricity momentarily. With this, you can avoid a high price for consumption and reduce energy consumption at the same time.
As the name suggests, the off-grid connection of the electricity company is part of the processes that allow you to switch off the external power grid and switch on your own power grid. During the process, the contactor separates the electricity supply from the electricity company or the home inverter. This helps to avoid the problems of short-circuiting, equalizers and makes it possible to buy residential electricity at the lowest possible price.
P.S. The contactor presented in the video was changed from its open switch (NC) tips to a more current-resistant one.
In the winter of 2023, the hard-working bees were sponsoring this video as well, which enabled the bee keeper to have winter time activities. So thank you to the bees who made this winter's fun and thought-provoking trip possible!
