5.8 An Installation Method of Energy Meter
Electrical Connection
The electrical installation method of the digital energy meter (energy meter) must comply
with installation method provided by the digital energy meter manufacturer. However, the
digital energy meter must be selected, as recommended by Samsung SDI in Chapter 6.3 on
the following page.
The [Figure 5-18] shows the electrical cable connection and the communication lines of the
digital energy meter. Depending on the product, there are a Uni-Direction meter and a Bi-
Direction meter. For the uni-direction meter, two lines must be connected, with one line in
the export direction and the other in the import direction. For the Bi-Direction meter, one
line can be used. Refer to the [Figure 5-18] and the communication description in Chapter 6
to install the digital energy meter.

The end system of the used lead wiring may be different with the energy meter chosen.
Therefore, refer to the energy meter manual.
5.9 A Connecting Method of the DC Line from the PV
Refer to the [Figure 5-19] for the PV module connection. The lead wire coming from the PV
module is connected to the distribution box. For the structure of the distribution box, refer
to subsection 5.7. For the connection to the distribution box, connect each to the terminals
of the solar energy of PV1+, PV1-, PV2+, and PV2-. On the other hand, connect the
distribution box terminals with the main body terminals (PV1+, PV1-, PV2+, and PV2-) of the
3.6 kWh All In One in proper order. The lead wire thickness is presented shown in the
following Table.
For the connectors (PV1+, PV1-, PV2+, and PV2-) between the distribution box and the 3.6
kWh All In One input, the following types of connectors are used (MC4 connector, PV-Stick
