Large-scale inverterPVmaster Outdoor technology
PVmaster Outdoor
The PVmaster Outdoor can be installed directly on the PV generator. This makes it suitable
in particular for PV power plants, where the power inverter cannot be housed in a suitable
building.
Resistant to environmental effects
The rugged design of the PVmaster Outdoor ensures efficient grid connection: Double-
walled housing and heat exchanger shield the power electronics effectively against
environmental effects. The PVmaster Outdoor is insensitive to dust, moisture and extreme
temperatures so that reliable operation is ensured at all times.
Power inverter
The heart of the PVmaster are power electronics developed at LTi that have demonstrated
their high quality as frequency converters in industrial drive engineering on a daily basis
for years.
Main switch
Integrated AC and DC switch-disconnectors enable simple isolation of the power inverter
in compliance with the requirements of VDE 0100-712.
Transformer
With the efficiency optimised isolating transformer, the DC side is decoupled from the
potential of the AC side. The earthing of a DC pole – as prescribed for the operation of
thin-film modules – is admissible.
Data logger
Operation of the PV power plant is recorded in the data logger. Recording input and
output quantities as well as temperature as daily curves allows early determination of the
optimal operation of the PV generator.
Communication
A logbook file and measured values are made available via the Internet (www.pvmaster.de)
or mobile phone network. Unexpected events are directly reported – either per e-mail or
SMS direct to mobile phone.
Overvoltage protection
Overvoltages can occur due to lighting strikes, switching operations and atmospheric
disturbances. Built-in overvoltage protectors limit the voltage and prevent failures.
Filters
The employed filters in conjunction with dynamic current control produce a line current
with a quality that exceeds standard requirements. The current distortion THD is < 2 %.
This makes it possible to operate the PVmaster also on “weak” power systems. PVmaster
can also contribute to improving the system voltage quality.
