CAUTION
■Q.HOME CORE 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 Qcells. (Connecting other
products to Qcells 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.
■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
■An internet connection is required to use all functions of Q.HOME CORE A5.
■Installation protocol must be filled out and sent to E-Service. (This is required only in Germany.)

8 Device Installation
8.3 Installation Requirements
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.
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.

1Assemble the stand legs.
■Bolt: M8 × 16 (included in the package)
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.
■Mounting hole: Ø17.5 mm
■Nut: M12 to 16 (not included in the package)

17
4Place the product on the bracket, secure the product to the bracket using
the M6 bolt.
■See steps 3 and 4 in the "8.4 Wall Mount".

9 Connecting the Cables
CAUTION
■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 o.
