Safety I 04
The Q.HOME+ESS HYB-G2 is designed for residential use. It is a single-phase, Grid-connected
system of solar energy sources and Li-Ion Battery energy storage.
The Q.HOME+ESS HYB-G2 uses solar energy power connected to the input/output terminal
installed on the side of the device in order to :
1) charge the Li-Ion Battery energy storage,
2) provide a supply to the household load, and
3) 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 Guidelines
DANGER
High voltages in power conditioning circuits. Lethal hazard of electric shock or
serious burns.
The following work on the ESS must be carried out by qualified personnel only.
• Electrical insulation
• Repairs
• Modification
Except when under supervision by qualified personnel, children or people lacking
physical, mental, or intellectual capabilities should not work on this system.
The system should be installed out of the reach of children.
Even when no external voltage is applied to the system, it may have internal high
voltage in the device, which can cause lethal damage to the human body.
High voltage can cause lethal damage to the human body.
CAUTION
When the photovoltaic array is exposed to light, it supplies DC voltage to the
Q.HOME+ESS HYB-G2.
Do not touch the PV cable when it PV cable is connected to the PV arrays.
CAUTION
After disconnecting the INVERTER from Battery or PV, wait 5 minutes to
discharge the INVERTER.
CAUTION
Li-Ion Battery energy storage system (ESS) inside. When assembling the system,
do not intentionally short the positive (+) and negative (-) terminals with metallic
object. All work on the ESS and electrical connections must be carried out by
qualified personnel only. The ESS within Q.HOME+ESS HYB-G2 provides a safe
source of electrical energy when operated as intended and as designed.
A potentially hazardous circumstance such as excessive heat or electrolyte mist
may occur due to improper operating conditions, damage, misuse and/or abuse.
The following safety precautions and the warning messages described in this
section must be observed. If any of the following precautions are not fully under
-stood, or if you have any questions, contact Customer Support for guidance.
The safety section may not include all regulations for your locale; personnel
working with Q.HOME+ESS HYB-G2 must review applicable federal, state and
local regulations as well as the industry standards regarding this product.

NOTICE
1. Over voltages in the power conditioning circuits.
Any damage to the Q.HOME+ESS HYB-G2 will result in voiding of warranty
claims.
Danger to life from electric shock due to damaged Q.HOME+ESS HYB-G2.
Inadvertent operation of damaged Q.HOME+ESS HYB-G2 can lead to a
hazardous situation that may result in death or serious injury due to electrical
shock. Only operate Q.HOME+ESS HYB-G2 when it is technically faultless
and in an operationally safe stat.
Regularly check the Q.HOME+ESS HYB-G2 for visible damage.
Make sure that all safety equipment is freely accessible at all times.
If the Q.HOME+ESS HYB-G2 is damaged, do not touch it. Please immediately
contact your installer or Q CELLS for arrange for a repair.
2. Please contact your installer or Q CELLS if a significant event message
is shown on the LCD screen or if the Q.HOME+ESS HYB-G2 reports an event.
Refer to the table of event messages for different significant/general events.
CAUTION
When transporting the Q.HOME+ESS HYB-G2, work with at least two persons

Operating Modes I 12

3. Operating Modes
This system is composed of six modes : PV Auto, PV Only, Battery discharge, Standby,
Maintenance (forced charge), and Stand-Alone (Back-up). The event check status should
not be considered as any specific mode.
3.1 Standby Mode
This is the standby mode before converting to operation mode (PV Auto, PV Only, Battery
discharge mode). Conversion to the operation mode (PV Auto, PV Only, Battery discharge
mode) is made by the EMS decision.
3.2 Event Check Mode
This mode stops solar energy generation and put it in standby mode as an event occurs.
3.3 PV-Auto Mode
This mode is divided into three types depending on the state of the Battery power.
3.3.1 Weak
Solar energy generation and Battery discharging are available. The solar-generated power
is supplied to sub and load. In case of insufficient power, the battery is discharged on
the EMS decision. When Load Output Power (Sub) is higher than power generation of PV
and Battery, Grid power supplied to the Sub.
• Use smart meter. The energy supply priority is : load (sub+main) > grid
• Not use smart meter. The energy supply priority is : sub_load > grid
