Proceed as follows:
1) Install the MCCB making sure that no electric load is interposed between the circuit breaker and the
SUNWAY M XS. Make sure that the current capacity of the electric system in the installation point of the
MCCB is adequate for the connection.
2) Connect the SUNWAY M XS and the MCCB using the cable assembly provided.
3) Once the electrical connection to the grid has been carried out, keep the circuit breaker open.
3.4.3.4. Connection to the Photovoltaic Field
CAUTION
The electrical connection of the SUNWAY M XS must be done following the
steps in section 3.4.3.
Each string is composed of a given number of series-connected PV modules. The PV generator may consist
of a single string or multiple parallel-connected strings. The configuration of the PV field should be defined
depending on the voltage range allowed by the SUNWAY M XS and on the power to be installed.
Up to four strings may be connected in parallel to the SUNWAY M XS, with no need to install any additional
component.
The strings forming the PV field and that are connected to the same SUNWAY M XS must be
dimensioned in order to get the same working voltage per string. It is recommended that the same type of
solar panels be used for the whole PV field and that all the strings be exposed to exactly the same solar
radiation.
The SUNWAY M XS is not compatible with strings comprising PV modules that require earthing one pole.
Quick-coupling connectors are used for the connection of the product to the PV field. The SUNWAY M XS
inverters are supplied with the following types of connectors:
•
Quick-coupling Multicontact MC4 connectors (panel connectors PV-ADBP4 and PV-ADSP4 and
floating connectors PV-KBT4 and PV-KST4). For assembly instructions, please consult the MA231
document available for download from the website of the manufacturer;
•
Amphenol Helios 4 connectors (panel connectors H4CFM6DN and H4CMM6DN and floating
connectors H4CFC6DN and H4CMC6DN). For assembly instructions, please consult “Assembly
Instruction for the Helios H4 PV Connectors” available for download from the website of the
manufacturer;
