5.7 A Connecting Method of the DC Line from the PV
Refer to the [Figure 5-15] 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 5.5.
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 Q.HOME+ ESS HYB G2 in proper order. For the connectors
(PV1+, PV1-, PV2+, and PV2-) between the distribution box and the QQ.HOME+ ESS HYB G2 input,
the following types of connectors are used. Refer to Chapter 5.1.2 for cable specification.
[ Figure 5-16 : PV Connector (Female) and PV Line (Male) ]
[ Figure 5-17 : PV Connector Connection (MC4 Type Connector Connection) ]
Check the cable connection of PV strings for the correct polarity and that the open circuit voltage
does not exceed the INVERTER input limit 550 V. If open circuit voltage is higher than 550 V,
status of INVERTER is fault.
The Male product is connected to the lead wire coming from the distribution box in the PV side,
and the Female part is attached to the Q.HOME+ ESS HYB G2. The two products are properly docked
when connected together.
When inserting or pulling out the PV connector (MC4 Type), be sure to turn off the DC disconnection
switch.
In the Q.HOME+ ESS HYB G2, the AC power input/output ports are plug type. Each cord shall be 6mm
and the diameter of the cable shall be approximately 18mm . The PE terminal is connected from the inside
of the product to the frame ground of the enclosure.
