3.2 Functional description
Broad input voltage range
The broad input voltage range provides you with flexibility in
connecting solar modules. You can use the space you have
available to optimum effect and at the same time reduce
installation costs.
Solar module protection
Conergy Three Level (CTL) Technology reduces leakage
currents, among other effects, which helps protect the solar
modules as well as other electrical components in the
photovoltaic system. This means you can use
Conergy IPG T series string inverters as transformerless
inverters in PV systems with special solar modules such as
thin-film modules (please check with the module
manufacturer).
Maximum Power Point
The yield of the photovoltaic system is increased when the
string inverter is optimally calibrated with the solar modules.
The system operates most efficiently at the Maximum Power
Point (MPP). All string inverters make use of MPP tracking.
This ensures that the system yield is optimised according to
the momentary irradiation conditions. This function
continually tracks and adjusts the optimum operating point in
the curve of the solar power system.
DC switch disconnector
The string inverters are fitted with DC switch disconnectors.
This switch disconnects the power exclusively from the
power unit of the string inverter. The solar generator cables
and the DC connections can continue to conduct electricity.
Surge voltage protection
The inputs of the solar power system and the outputs to the
public grid are fitted with Category D (type 3) surge voltage
protection. The surge voltage protection does not provide
protection against higher DC voltages (see chapter 3.7,
page 19).
