1 Information in this Manual
1.1 About This Manual
This is the installation manual for Q.HOME CORE H4 / A4 / H5 / A5. Please read this installation and
user manual carefully before installing and operating Q.HOME CORE H4 / A4 / H5 / A5. It contains
important safety instructions. The warranty will be void if you fail to follow the instructions in this
manual.
1.2 Target Group
Electricians and qualied technicians who are allowed to install and to connect electrical systems.
1.3 Symbols Used in This Manual
This symbol indicates a hazardous situation which could result in death or serious injury,
if not avoided.
This symbol indicates a hazardous situation which could result in minor or moderate
injury, if not avoided.
Prohibited.
Note This indicates valuable tips for installation of the product.

2 Safety
The safety section may not include all regulations for your locale; personnel working with
Q.HOME CORE H4 / A4 / H5 / A5 must review applicable federal, state and local regulations as well
as the industry standards regarding this product.
2.1 Intented Use
Q.HOME CORE H4 / A4 / H5 / A5 is designed for residential use only. It should not be used for
commercial or building. It is a single-phase, Grid-connected system of solar energy sources and Li-
Ion Battery energy storage.
Q.HOME CORE H4 / A4 / H5 / A5 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.
Inverters should not be installed in multiple phase combinations. 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 Q CELLS will nullify the product’s guarantee.
For example, Q CELLS 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 Q CELLS 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.
• All work on the ESS and electrical connections must be carried out by qualied
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 live inner
components may lead to electric shock, causing death or serious injury.
• Before maintenance, turn off the equipment and strictly comply with the safety
precautions stated in this manual.

7
Safety
• 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 Neutral Continuity (only for Australia)
Regardless of the protection situation, the neutral line relay of Q.HOME CORE is always closed.
2.5 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 maintenace to
prevent electric shock.
Warning: Explosion
Do not expose to heat or flame. Keep away from flammable substances.

Safety
8
Warning: Corrosive Subsatances Leaking
Do not disassemble or modify the battery. Otherwise, corrosive substances
may leak.
2.6 Disposal
1 Disposal of Q.VOLT
• When this crossed-out wheeled bin symbol is attached to a product, it means the
product is covered by the European Directive 2002/96/EC.
• All electrical and electronic products should be disposed of separately from
the municipal waste stream via designated collection facilities appointed by the
government or the local authorities.
• The correct disposal of your old appliance will help prevent potential negative
consequences for the environment and human health.
• For more detailed information about disposal of your old appliance, please contact
your city office, waste disposal service or the shop where you purchased the
product.
2 Disposal of Q.SAVE
• When this crossed-out wheeled bin symbol is attached to batteries/accumulators
of your product, it means they are covered by European Directive 2006/66/CE.
• This symbol may be combined with chemical symbols for mercury(Hg),
cadmium(Cd) or lead(Pb) if the battery contains more that 0.0005% of mercury,
0.002% of cadmium or 0.004% of lead.
• All batteries/accumulators should be disposed separately from the municipal waste
stream via designated collection facilities appointed by the government or the local
authorities.
• The correct disposal of your old batteries/accumulators will help to prevent
potential negative consequences for the environment, animal and human health.
• For more detailed information about disposal of your old batteries/accumulators,
please contact your city office, waste disposal service or the shop where you
purchased the product.
