2.1.1 Installation Application Suitable for Safety
This device, Q.HOME+ESS HYB-G2, is designed to be suitable for household purposes.
The PV Input terminal is composed of two Strings. One PV String input must install 3.3 kW
or less PV panel capacity, and the maximum input voltage of the PV String must be limited
to 550V or less.
As shown in the [Figure 2-4], the Q.HOME+ESS HYB-G2 uses the two independent channels
of the PV Input ({PV1+, PV1-}, {PV2+, PV2-}). They are used independently for running the
maximum power from the sources of PV1 and PV2. Two channels are recommended for
independent use for the two PV Inputs. Make sure not to connect one PV string in parallel with
the two independent PV inputs (PV1, PV2). (Refer to Q.HOME+ESS HYB-G2 Solar energy input
connection in the [Figure 2-4]). PV common mode is not allowed.
※ PV modules shall have an IEC61730 Application Class A rating or equivalent.
To connect Q.HOME+ESS HYB-G2 with the Public Grid, make sure to install the watt-hour
meter recommended by Hansol Technics (refer to the installation manual) and to install the
distribution box between Q.HOME+ESS HYB-G2. And the Grid watt-hour meter.
Before installing the distribution box, select a suitable location complying with the IP21 and
use the equipment recommended by the installation company. Please note that failure to do
so may cause malfunction and the product will not be guaranteed for any accident or damage.
Refer to the installation manual for further information. The [Figure 2-5] shows the connection
diagram on the distribution board. The distribution box receives the DC input (the PV string 1
and the PV string 2) from the solar energy module. The power system is connected to the
INVERTER. House (Load) is connected to the INVERTER Load.
The DC disconnection switches displayed in the box below are already mounted on the
product so you don’t need to install them.
