2 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 LiIon 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. 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 ServiceHotline.
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.
5

Safety

· This product is intended to be used for PV source inputs and residential home grids (AC 230V). If not used as intended, the protection provided by the equipment may be impaired.
· This product is designed appropriate for two-PV string structure. Therefore, the PV string 1 and PV string 2 must be connected to PV input 1 and PV input 2, respectively. Do not split one PV string output for connecting it into the PV input terminal 1 and input terminal 2.
· After disconnecting the inverter from the battery pack or PV, wait 5 minutes to discharge the inverter.
· Do not touch the PV cable when the product is connected to the PV arrays. When the photovoltaic array is exposed to light, it supplies DC voltage to the product.
· 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.
2.3 Earth Fault Alarm
When an earth fault occurs, the inverter stops operation and the buzzer operates for 2 minutes. Note: This feature is only supported on models released in Australia.
2.4 Product Safety Labels

Wear eye protection at all times (installation, maintenance, etc.)

Follow the instruction in this manual for service and replacement.

Caution: Risk of Eelectirc Shock Alternating current (AC) and direct current (DC) sources are connected to this device. To prevent risk of electric shock during installation or maintenance, ensure that all AC and DC connections are disconnected.
Caution: Hot Surface Metallic parts of enclosure may be hot during operation.
Caution: Risk of Electric Shock Hazardous voltage is still present 5 minutes after all power sources have been disconnected. Wait for at least 5 minutes before maintenace to prevent electric shock.
Warning: Explosion Do not expose to heat or flame. Keep away from flammable substances.
Warning: Corrosive Subsatances Leaking Do not disassemble or modify the battery. Otherwise, corrosive substances may leak.

7.1 ON-Grid Mode

1 Daytime On-Grid
· PV Power > Load Power: The PV power is preemptively supplied to the household load (Critical load + Main Load), and then it charges the battery. If PV energy remains, it is operated according to the operation mode as below. – Self consumption mode: The remaining PV energy is supplied to Grid. – Zero export mode: Q.VOLT decreases the PV generation amount.
· PV Power < Load Power: If the PV power is less than the household load (Critical load + Main Load) power, the battery discharges to provide the short household load energy. If the PV + battery power is less than the load power, the short load power is supplied from the grid system.

8.4 Battery Management

· Backup SOC: The minimum SOC that the battery maintains in order to supply power to the load in the case of Off grid.
– Battery SOC < Backup SOC (On-grid mode): Q.HOME CORE does not discharge the battery but only performs charging operation.
· Charge Management: If the PV power is greater than the load power, the inverter charges the battery. If the battery SOC reaches 100 %, the battery converter stops its operation not to be overcharged.
· Discharge Management: Discharge Management effectively prevents the battery from being damaged due to overcharge. If the battery SOC (State of Charge) reaches 5 % or the Backup SOC, it limits the battery discharge.
· Cell balancing: If the inter-cell potential difference exceeds the threshold voltage, the PCS automatically starts cell balancing control to prevent the battery from damage due to the potential difference among battery cells.
· Parallel Connection: In the Q.SAVE parallel connection, internal module relays is not connected if voltages are different between each battery module. Then, the battery management system automatically controls charging/discharging power of each battery to achieve the identical Q.SAVE voltage. When the voltage of each module becomes equal, the internal relays are connected.

Features

· Power derating: It limits the charging/discharging power on over-temperature /under-temperature to protect the battery from overload or other potential errors. If the temperature does not drop beyond a certain period, the BDC stops its operation.
8.5 Demand Response Modes (DRMS)

The inverter supports the DRM (Demand Response Mode) function as specified in AS 4777.2 2015.

Mode DRM 0 DRM 1 DRM 2 DRM 3
DRM 4
DRM 5 DRM 6 DRM 7
DRM 8

Discription The inverter is in the state of “Key-stop.” The import power from the grid is 0. The import power from the grid is no more than 50 % of the rated power. The import power from the grid is no more than 75 % of the rated power. The import power from the grid is no more than 100 % of the rated power, but subject to the constrains from other active DRMs. The export power from the grid is 0. The export power from the grid is no more than 50 % of the rated power. The export power from the grid is no more than 75 % of the rated power. The export power from the grid is no more than 100 % of the rated power, but subject to the constrains from other active DRMs.

8.6 Dark Start
Dark Start feature allows you to turn on Q.HOME CORE when there are no PV and Grid: For details about how to use the Dark Start, see “4.2 Using the Dark Start button” on page 12. Note In case of Dark Start, if the battery SOC is below 5%, Q.HOME CORE stops its operation and is turned off again.

9 Maintenance
9.1 Cleaning the Cover
Qualified Person Only! If Q.HOME CORE is dirty, clean the enclosure, the enclosure cover and the LED using only clean water and a soft cloth. Ensure that the Q.HOME CORE is free of dust, foliage and other dirty.
