In the light of continuously rising electricity prices, an independent power supply is becoming increasingly attractive. The first step to independence is your own photovoltaic system. The second is to combine it with an intelligent inverter and a solar power storage unit. This allows you to use up to 70% of the electricity you produce for your own needs. In addition to this, you also have the option of using the electricity even if the sun is not shining and you are also protected against possible electricity grid outages.
