2.4 System Diagram and Connection Label
The IGSI “DJ/3” series are three-phase solar inverters with two independent channels of
MPPT input. They are designed to convert the direct current generated by PV panels into
three-phase 400Vac 50Hz alternating current for delivery into the AC grid.
The IGSI “DJ/3” series can be used in an on-grid PV system to produce electricity.
The installation of the IGSI “DJ/3” series and their connection to the AC grid shall be done in
accordance with local regulations and may require the installation of adequate electricity
consumption measuring devices.
The IGSI “DJ/3” series only operates when it is connected to the AC grid and cannot
operate as a stand-alone unit.
The simplified connection diagrams of the inverter are as figures 7 & 8 below.

NOTE: Ensure that the IGSI-xxxxDL/3 inverter is not exposed to direct sun radiation or
other external heat sources, including heat from units below it (see fig.6). At times, the
heat generated by the inverters installed at the bottom rows could increase the ambient
temperature and this may be detrimental to the inverters located in the top rows. At temperature above
50°C, output power of the top row units could be derated. Derating is more significant in case of high
output power and high ambient temperature. For proper cooling, do make sure to allow unobstructed
air flow at installed location (for instance, never with the front panel facing a solid surface).
Fig. 9 Connections on the bottom of the inverter
A. PV Panels: Provide DC power to inverter.
B. Solar inverter: Converts DC (Direct Current) power from PV panel(s) to AC (Alternating
Current) power. As the Inverter is grid-connected, it controls the current amplitude
according to the PV Panel power supply. The PV inverter always tries to convert the
maximum power from your PV panel(s).
C. DC Switch and AC Switch: “DC switch” is located between PV Panels and solar inverter
while “AC Switch” located is between AC Grid (Utility) and solar Inverter. They are
simplified in this diagram. Usually, they may consist of electrical breaker, fuse and/or
connecting terminals. To comply with local safety standards and codes, the connection
system should be designed and implemented by a qualified technician. The solar inverter
also has an option of an integrated DC switch demonstrated in dashed border in Fig.6. –S
suffix indicates the inverter is integrated a DC switch in PV input side.
D. AC Grid (Utility): Referred to as “grid” in this manual, is the way your electric power
company provides power to your place. Please note that Inverter can only connect to
low-voltage systems (namely, 400Vac, 50Hz).
E. PV INPUT: Connected to PV Panels by the attached terminals.
F. RS232: Connected to monitoring computer by special RS232 cable provided.
G. RS485: daisy-chain communication for one or more inverters.
H . AC TERMINAL (three blocks in right hand): Connected to AC Grid.
Note: There is an option of an integrated switch box that includes DC switch, AC switch,
DC fuse, AC fuse, DC SPD and AC SPD devices as an option. Such a product is also
readily available from your local market.
2.5 Connecting to the AC Grid (Utility)
A. Measure AC grid (utility) voltage and frequency. It should be 400VAC, 50Hz, three-phase.
B. Open AC Switch between solar inverter and AC Grid (Utility).
