Large-scale invertersWhat we do
LTi REEnergy GmbH as one of the fastest growing companies in the group has been highly active
in the area of renewable energies for more than a decade. The three main segments in which the
company is active in this area are wind energy, biomass and photovoltaics.
In the photovoltaics segment, LTi REEnergy offers the PVmaster 450 series. These state-of-the-art
large-scale inverters for photovoltaic energy systems are available from 33 kW and are ideal for
modules employing thin-film technology and silicon.
In the wind energy segment, LTi REEnergy offers power inverters and complete drive systems for
electric rotor blade control for wind turbines. The delivery of over 5,000 systems and components
delivered until 2007 makes us a leading supplier worldwide.
In the biomass segment, the company develops and produces systems for the utilisation
of process heat. These generators are used in biogas, bio-oil and wood gasification plants
as well as solar thermal systems employing an ORC process and supply the power won
from the waste heat to a central power supply system via a power inverter.
Who we are Why PVmaster
The LTi company group is a pioneer in power inverter technology with more than 35 years’ experience in this field. With The PVmaster offers reliability, convenience and high efficiency.
technologically sophisticated drive solutions in the industrial environment, where more than 1 million inverters have been
