2What 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 wind energy segment, LTi REEnergy offers power inverters and complete drive systems for
electric rotor blade control for wind turbines. The delivery of over 7,500 systems and components
delivered until 2008 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.
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.
Why PVmaster Station
PVmaster Stations offers reliability, comfort and high efficiency.
The compact mechanical room cells contain PVmaster large-scale inverters, a low and medium
voltage substation, as well as a medium voltage transformer, which are available in the power
range from 0.2 to 1 MW.
No matter if you decide in favour of a concrete space cell or a steel panel container, your
PVmaster Station will be delivered ready-for-use to your PV park and can directly be put into
operation.
The PVmasters journalise the daily serial data curves of all in- and output parameters. The out-
put will be provided to you on a daily basis via e-mail. Further data can be reviewed if necessary
and downloaded at the PVmaster portal in the Internet.
In case of any exceptional incidences you will be informed immediately via e-mail or text mes-
sage by the PVmaster Station. By request, we also provide to monitor your entire PV park and
offer you service and maintenance contracts.
