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.
