Must be understood as Ortronic^® system the group of apparatuses which compose an installation for an specific application.

An off–grid system is composed by the same components described for the emergency systems, plus an electric generator set that usually needs diesel for its functioning.

1.1 Besides of the electrical generator set, in an Ortronic^® off–grid system, photovoltaic        solar panels, wind generators and any other type of electric generator set, with        output on AC or DC,can be used.

1.2 One of their best applications is the energy saving in the communications shelters        for cellular phones, where the energy represents the 70% of the total cost of the        operation.

1.3 They are the best possible solution for supplying electricity to those who are not        connected to the electrical grid.

1.4 The economic houses, or houses with energy, are a special application and, as they        are progressing at a high speed, they are getting to be other of the most        important applications.

1.5 For the houses with energy, Ortronic^® has developed a special systems line that,        used together with Climaterra^®, are the ideal solution with energy savings that reach        until 90%, see Houses with energy, or Climaterra^® cooling systems.

2 Ortronic^® Off–grid systems advantages:

2.1 Equally to the emergency systems, an off–grid system is a group of devices        connected between them that work under the orders of several synchronized        microprocessors, which are the heart of the system.

       As mentioned when talking about the Ortronic^® emergency systems advantages,        the Ortronic^® off–grid systems have all the advantages of the Ortronic^® converters        and battery chargers, although all the advantages are not applicable in all the        applications and not all the converters are manufactured for including all the        advantages.

       In fact, the unique application that can utilize all the Ortronic^® converters advantages        are the electrical vehicles.

2.2 The Ortronic^® off–grid systems are the best possible solution for supplying electricity        to those who are not connected to the electrical grid.

2.3 The electrical energy is generated by a private electric generator set, which normally        consumes diesel. This is the cheapest energy when no connected to the electrical        grid.

2.4 In this application, as the electric generator set is owned by the user, he is also        benefited by the similar advantage explained above for the Ortronic^® emergency        systems, which says that the electric generator sets, with an Ortronic^® converter        connected at their output, will always supply an active power, in kW, equal to its        maximum power in kVA, independently of the power factor of the loads.

       This advantage increases the energy savings, going over 70%, compared to any        other system that can be found in the market.

2.5 In most cases, the total cost of an Ortronic^® off–grid system, including its installation,        is lower than the cost of the transport of the electrical line.

2.6 For the villages all around the world that nowadays don’t have electricity, the        Ortronic^® solution is more profitable than installing electric power plants and        distribution lines.

2.7 Big electrical distribution lines are very expensive, they kill too much protected        species of birds, deform the landscape and loses about 30% of the energy by        radiations to the environment, which is not healthy for the living beings.

       Today, the big distribution lines can't compete with the Ortronic^® systems.
