Up to 90% independence with your own photovoltaic system

Make yourself up to 90% independent with our "fri"-Package!

You can achieve 90% self-sufficiency with the so-called “island solution”: A photovoltaic island system works completely independently and is not connected to the public power grid.

Instead of storing excess energy in the public power grid, the system temporarily stores the electricity in batteries until you need it. This means you can be sure that the stored solar power will be used when the sun is not shining. This means not just at night, but also on rainy or cloudy days. 

Become now fri!

The two types of island solution

When it comes to solar stand-alone systems, a distinction is made between two types of systems: 1. the stand-alone solution without a grid connection and 2. the stand-alone system for power supply in the event of a power failure.

Island system completely without mains connection

If you would like to completely separate yourself from the public power grid, we will plan and design your photovoltaic island system so that its size and performance are designed to independently supply your entire house.

Island system for emergency power supply

What happens if the power suddenly goes out?
With an island system for emergency power, you will no longer have to worry about power outages in the future. An island system for backup power allows you to convert your normal feed-in system into an island system in an emergency and switch to backup power within a few seconds.
