3 Safety
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.)
