2 Safety
The safety section may not include all regulations for your locale; personnel working with
Q.HOME CORE H5 must review applicable federal, state and local regulations and the industry standards
regarding this product.
2.1 Intended Use
Q.HOME CORE H5 is designed for residential use only. It should not be used for commercial or construction
area. It is a single-phase, Grid-connected system of solar energy sources and Li-Ion Battery energy storage.
Q.HOME CORE H5 uses solar energy power connected to the input/output terminal installed on the side of the
device in order to:
■charge the Li-Ion Battery energy storage,
■provide a supply to the household load, and
■convert direct current (DC) electricity of the Battery to alternating current (AC) to discharge as household
single-phase load or electric system.
This device should not be used for any purpose other than the purpose described in this installation manual.
Any substitute use of this device, random change in any of its parts, and use of components other than sold or
recommended by Qcells will nullify the product’s guarantee.
For example, Qcells Li-Ion Battery energy storage should not be replaced by other manufacturer’s Battery
storages. For further information on proper use of this device, contact the Qcells Service-Hotline.
2.2 Safety Precaution
The following safety precautions and the warning messages described in this section must be observed. If
any of the following precautions are not fully understood, or if you have any questions, contact the customer
support for guidance.
WARNING
■All work on the ESS and electrical connections must be carried out by qualified
personnel only.
■High voltages in power conditioning circuits. Lethal hazard of electric shock or
serious burns. Wear rubber gloves and protective clothing (protective glasses and
boots) when working on high voltage/high current systems such as the inverter and
battery systems.
■This product provides a safe source of electrical energy when operated as intended
and as designed. But a potentially hazardous circumstance such as excessive heat
or electrolyte mist may occur due to improper operating conditions, damage, misuse
and/or abuse.
■Do not connect or disconnect PVs, batteries, and grid connectors with the power on.
Otherwise, it may generate electric arcs or sparks, causing fire or injury.
■Do not open the enclosure while the inverter is operating. Touching inner
components under running condition may lead to electric shock, causing death or
serious injury.
■Before maintenance, turn off the equipment for at least 5 minutes and strictly comply
with the safety precautions stated in this manual.

7
Safety
CAUTION
■This product is intended to be used for PV source inputs and residential home grids
(AC 230V). If not used as intended, the protection provided by the equipment may
be impaired.
■This product is designed appropriate for two-PV string structure. Therefore,
the PV string 1 and PV string 2 must be connected to PV input 1 and PV input 2,
respectively. Do not split one PV string output for connecting it into the PV input
terminal 1 and input terminal 2.
■After disconnecting the inverter from the battery pack or PV, wait 5 minutes to
discharge the inverter.
■Do not touch the PV cable when the product is connected to the PV arrays. When
the photovoltaic array is exposed to light, it supplies DC voltage to the product.
■In case of short circuit, high-voltage components inside the inverter may influence
the product or other properties. Cover the product or take other precautions to
prevent metal objects from entering inside during installation and wiring.
2.3 Earth Fault Alarm
When an earth fault occurs, the inverter stops operation and the buzzer operates for 2 minutes.
Note: This feature is only supported on models released in Australia.
2.4 Product Safety Labels
Wear eye protection at all times
(installation, maintenance, etc.)
Follow the instruction in this manual for
service and replacement.
Caution: Risk of Electric Shock
Alternating current (AC) and direct current (DC) sources are connected to this
device. To prevent risk of electric shock during installation or maintenance,
ensure that all AC and DC connections are disconnected.
Caution: Hot Surface
Metallic parts of enclosure may be hot during operation.
Caution: Risk of Electric Shock
Hazardous voltage is still present 5 minutes after all power sources have
been disconnected. Wait for at least 5 minutes before maintenance to
prevent electric shock.
Warning: Explosion
Do not expose to heat or flame. Keep away from flammable substances.
Warning: Corrosive Substances Leaking
Do not disassemble or modify the battery. Otherwise, corrosive substances
may leak.

4 Installation requirements
4.1 Installation Environment
CAUTION
■Although it supports the waterproof performance equivalent to the IP65 rating,
install in a place not directly exposed to direct sunlight, rain, and snow.
■If the product is installed in direct sunlight, abnormal operation may occur due
to high internal temperature of the product, and if the product is damaged or
malfunctions due to this, the product may be excluded from the warranty.
Make sure the installation site meets the following conditions:
■Not in areas where highly flammable materials are stored.
■Not in potential explosive areas.
■Not near the television antenna or antenna cable.
■Not higher than an altitude of about 2000m above sea level.
■Under good ventilation conditions.
■The ambient temperature in the range of -10 °C to 45 °C
■While it can be installed by slanting it backward up to 5 degrees or lower, do not install it tilted on the side. The
wiring area should point downward.
