Basic Information On The Device - Siemens SITOP solar User Manual

3.1 Basic Information on the Device

PV systems can be implemented with an AC power of up to 4.6 kW when you
combine different inverter. The following table gives information about the possible
combination.

Systems with 3.8 kW can be implemented by combining a SITOP solar 2300
MASTER with a SITOP solar 1500 SLAVE.
The primary differences between a MASTER and the SLAVES are the power
monitoring unit integrated in the device (ENS in accordance with DIN VDE0126-1-1)
and a powerful microprocessor system for operation and control of the indicators.
The system also offers the following features.
• Own MPP tracker on the MASTER and every SLAVE for separate operation of PV
generators (strings). This is a particular advantage when the subgenerators are
designed differently or when different module types are used.
• Wide input voltage range for optimum flexibility when planning systems and
selecting modules
• Low weight due to transformerless technology and active ventilation
• Standard integration of isolation monitoring of the solar generator
• Integrated all-current-sensitive, fault current circuit breaker (FI)
• Backlit display with 16 characters for indicating relevant measured values
• Serial RS 232 interface for easy connection of a PC or, if desired, a modem for
remote polling
The device has galvanic isolation and meets the requirements for secure
electrical isolation in accordance with EN 50178.
• Powerful integrated data logger for 8 measured values
The logger can be read with the free evaluation software SITOP solar log.
• Possible connections for sensors for measuring the emission and the module
temperature (ET100 or equivalent)
In addition, the impulse output (S0 output) of a digital counter can be connected
for AC power acquisition.
