This symbol indicates a hazardous situation which could result
in a light injury, if not avoided.
Note This indicates valuable tips for installation of the product.
3 Safety
• Q.HOME CORE H4/ A4 /H5 / A5 are hybrid PCS including an
inverter and batteries. The inverter weighs about 37.5 kg, and battery
pack weighs about 61.1 kg. Therefore, special care is required when
handling. At least two people have to carry and take it out.
• Do not operate with other components not approved by Q CELLS.
(Connecting other products to Q CELLS products may result in
abnormal operation.)
• All tasks regarding the PV module, inverter, and battery system
must be performed by certified personnel. Wear rubber gloves and
protective clothing while working.

6
English
• 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.
4 Requirements
• The internet connection is required to use all functions of
Q.HOME CORE H4/ A4 /H5 / A5.
• Installation protocol must be filled out and sent to E-Service. (This is
required only in Germany.)

7 Device Installation
7.1 Installation Requirements
Installation Environment
• For convenient maintenance, install the inverter at eye level.
• Secure the space for maintenance before installation.
• Although it supports the waterproof performance equivalent to the IP65
rating, install in a place not directly exposed to direct sunlight, rain, and
snow.
• 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.
5˚
Installation Space
For efficient heat mission, a sufficient distance should be secured from
the surrounding objects and sufficient space for cable connection is
required.

1Check the location of a hole of the bracket and drill a hole on the
wall.
• Mounting hole: Ø9
2Insert an anchor into the hole and fix the bracket with a bolt.
• Use the wall mount bolts included in the Q.VOLT package.
• At least 4 bolts are required to secure the bracket.

English
3Place the product on the bracket.
4Secure the bottom of the product to the bracket using the M6
bolts.
7.3 Floor Mount (Option)
1Assemble the stand legs.
• Bolt: M8 × 16 (included in the package)

14
English
2Fix the bracket to the stand legs.
• Bolt: M8 × 45
• Use the wall mount bolts included in the Q.VOLT package.
3Fix the stand on the floor.
• Nut: M12-16 (not included in the package)
4Place the product on the bracket, secure the product to the bracket
using the M6 bolt.
• See steps 3 and 4 in the "7.2 Wall Mount".

15
English
8 Connecting the Cables
• Before connecting electrical cables, make sure the AC circuit breaker,
PV switch, and DC switch are OFF.
AC Circuit Breaker: OFF
(in the junction box) PV Switch: OFF
(in the inverter)
DC Switch: OFF
(in the battery pack)
• Batteries can be replaced only by qualified personnel. If the battery
needs to be replaced, you must use a battery that meets the
manufacturer’s specifications.
• Make sure to match the polarity of the cables properly when
installing. Otherwise, it may cause electric shock or the product may
permanently be damaged. The damage from this is not covered by
the warranty.
• Before batteries are connected, all other connections should be done
and the battery interrupter must be off.

• Before connecting or disconnecting the PV cables (Connectors: MC4
type), make sure the PV switch is turned off.
• Make sure the PV cables are connected with the correct polarity.
• Make sure the open circuit voltage does not exceed the inverter input
limit 600 V. Otherwise, the status of inverter is fault.
Note: PV connectors are not available for A4S and A5S models.
