5.8 A Connecting Method of DC and AC Line
Refer to the [Figure 5-28] 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
Scalable 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 All in
One input, the following types of connectors are used (MC4 connector, PV-Stick Photovoltaic
