2 Safety
The safety section may not include all regulations for your locale; personnel working with
Q.HOME CORE H4 / H5 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 / H5 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 / 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 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.

Safety
6
• 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 maintenace to
prevent electric shock.
Warning: Explosion
Do not expose to heat or flame. Keep away from flammable substances.
Warning: Corrosive Subsatances Leaking
Do not disassemble or modify the battery. Otherwise, corrosive substances
may leak.

4.3 Turning Off Q.HOME CORE
If the AC circuit breaker cannot remain switched on after commissioning (e.g. because
the new meter has not yet been installed), the DC switch on the hybrid inverter must
remain switched on to avoid deep discharge of the battery. Alternatively, the device can
also be switched off completely.
To turn off the Q.HOME CORE:
1Turning off the battery DC switch.
2Turning off the PV switch.
3Turn off the AC circuit breaker in the junction box.
Note
After turning off the Q.HOME CORE, the DC and PV swiches can be locked for safety.
For details about locking the DC and PV swiched, see "16 Power Off" in the installation manual.

7 Operating Mode
7.1 ON-Grid Mode
1 Daytime On-Grid
• PV Power > Load Power: The PV power is preemptively supplied to the household load (Critical
load + Main Load), and then it charges the battery. If PV energy remains, it is operated according to
the operation mode as below.
- Self consumption mode: The remaining PV energy is supplied to Grid.
- Zero export mode: Q.VOLT decreases the PV generation amount.
• PV Power < Load Power: If the PV power is less than the household load (Critical load + Main
Load) power, the battery discharges to provide the short household load energy. If the PV + battery
power is less than the load power, the short load power is supplied from the grid system.
