OFF-GRID
An off-grid system may be necessary for locations or situations where there is no electricity network. In an off-grid system, self-generated energy is converted into electricity, which needs to be stored in, for example, batteries or hydrogen.
Examples where Green Power Supplies provides these systems are the mobile and maritime sectors, as well as for homes or businesses where there is no electricity network, such as buildings on an island, in the mountains, or in remote areas. We have a lot of experience in Africa where schools, hospitals, clinics, or businesses are fully dependent on an off-grid installation.

But we also provide ready-to-use systems for vacation homes in Italy, the Ardennes, France, Spain, and Portugal.
In most systems, solar panels provide at least 80% of the required energy. Sometimes this is supplemented with electricity from a wind turbine. In some cases, a backup diesel generator is used if the combination of wind and solar is not sufficient. In the mobile and maritime markets, the existing dynamo is often utilized.
Solar panels:
Solar panels: For the use of solar panels, there are 2 options, or a combination thereof:
● Solar panels supply 230 Volt AC through a grid inverter.
● Solar panels supply 12-24-48 Volt DC through a DC charger.
For all the power that needs to be stored, the most efficient solution is to charge it with a DC charger directly to the battery. All the power that is immediately needed during the day does not have to be supplied via a battery and can, therefore, be delivered directly to the users through a grid inverter.
Depending on the project, the most ideal solution is a combination of both, which can work together easily and flawlessly in one system.
Generators:
Less sustainable than solar or wind, but often essential for 100% guarantee of electricity, is the addition of a generator to the system. It is only used when the batteries are running critically low or in the event of a system failure when electricity is still required.
The combination of solar, wind, and a generator is often used in construction or road works. Fuel savings can reach up to 70%, resulting in reduced emissions, fuel costs, and maintenance expenses. The lifespan of a generator is also significantly longer.
Wind energy:
Similar to solar panels, there are 2 choices:
● A wind turbine supplies 230 Volt AC through an AC inverter.
● A wind turbine supplies 12-24-48 Volt DC through a DC charger.
For all the power that needs to be stored in a battery, the most efficient solution is to charge it with a DC charger directly to the battery. All the energy that is immediately needed during the day does not have to be supplied via a battery and can, therefore, be delivered directly to the users through a grid inverter.
