Chapter 3 Site Selection Requirements

Tips

• The warranty applies when the equipment has been installed properly for its intended use and in accordance with the operating instructions.

Installation

Installation Environment Requirements

• Do not install the equipment in smoky, flammable, or explosive environments.
• Avoid exposing the equipment to direct sunlight, rain, standing water, snow, or dust. Install the equipment in a sheltered place. Take preventive measures in operating areas prone to natural disasters such as floods, mudslides, earthquakes, and typhoons.
• Do not install the equipment in an environment with strong electromagnetic interference.
• Ensure that the temperature and humidity of the installation environment comply with the equipment’s requirements.
• The equipment should be installed in an area that is at least 500 m away from corrosion sources that may result in salt damage or acid damage (corrosion sources include but are not limited to seaside, thermal power plants, chemical plants, smelters, coal plants, rubber plants, and electroplating plants).

Installation Position Requirements

• Do not tilt or overturn the equipment to ensure that it is installed horizontally.
• Do not install the equipment in places easily touched by children.
• Do not install the equipment in places with fire or damp.
• Please keep away from the daily work and living places.
• Do not install the equipment in a sealed, poorly ventilated location without fire protection measures and difficult access for firefighters.
• Do not install the equipment in mobile scenarios such as RVS, cruise ships, and trains.
• You are advised to install the equipment in a location where you can easily access, install, operate, maintain it, and view the indicator status.
• When installing the equipment in the garage, do not install the equipment in the position where the vehicle passesthrough to avoid collision.

Mounting Surface Requirements

• Do not install the equipment on a flammable carrier.
• The installation carrier must meet load-bearing requirements. Solid brick-concrete structure, concrete walls, and ground are recommended.
• The surface of the installation carrier must be smooth and the installation area must meet the installation space requirements.
• No water or electricity is routed inside the carrier to prevent drilling hazards during equipment installation.

Tips

• The maximum operating temperature range applicable to the equipment is -20°C to 55°C, and the recommended optimal operating temperature range is 10°C≤T≤35°C.
• When the battery pack temperature is below 0°C, immediate charging is not possible, and the battery pack (the built-in heating module can be automatically enabled) will activate the heating feature automatically. The best charging performance of the battery can be achieved after heating for less than 2h. The heating feature will consume power.
• At a temperature > 40°C, the operation of the equipment may trigger a power derating that prevents the equipment from operating optimally. The higher the temperature, the shorter the service life of the equipment.

Chapter 4 Equipment Installation and Wiring

• Only company authorized personnel should install and connect the equipment. For details, see Energy Controller Home Installation Guide – Single-phase System A1.

Chapter 5 System Operation

Working Mode

Tips

• There are four operating modes of the energy storage system: Al Mode, Self-Consumption Mode, Fully Fed to Grid Mode, Time-based Control Mode. The Al Mode is recommended.
• Al Mode can be used in some countries, which is explicitly stated on the App interface.

Al Mode

• By recording the peaks and troughs of users’ consumption habits and local electricity prices for a period of time, Al mode can customize smart electricity solutions to maximize savings for customers.

Self-Consumption Mode

• When there is sufficient solar power, the electric energy generated by the PV system will first be used to power the loads, with any excess energy being stored in the batteries. If there is still surplus energy, it will flow into the power grid.
• When there is insufficient solar power, the batteries will release electric energy to loads. By increasing the self- consumption ratio of the PV system and improving the self-sufficiency ratio of household energy, you can effectively save on vour electric bills.

Fully Fed to Grid Mode

• The PV power generation can be maximized for sale to the power grid. During the daytime when the PV-generated power is greater than maximum output capacity of the inverter, the inverter stays at maximum output while the excess electricity is stored in batteries; when the PV-generated power is lower than maximum output capacity of the inverter or when no PV power is generated at night, the batteries are discharged to ensure that the inverter can maximize the output.

Time-based Control Mode

• In Time-based Control Mode, the charging period and discharge period should be manually set in the Haier Smart Cube App, and the other periods are non-charging and non-discharging ones. The surplus electricity generated by PV during the day can be sold to the grid or charged to the battery, and the battery can be charged at night during the period of low electricity price of the grid to save electricity costs.

Backup Reserve

• If there is a Gateway in the network, you can manually set the “Backup Reserve” value in Haier Smart Cube App. When the grid is connected, the battery stops discharging when the set backup SOC is reached; when the grid is powered down, the battery power from the backup can be used.

Example:

• Self-Consumption Mode involves backup SOC.

LED Indicator State

• Energy Controller Indicator

Note:

• If the system does not work properly please contact the customer service at customer service at https://eur.nahui-newenergy.com/service.html

Equipment Power-on/Power-off

• Tap “Setting” in Haier Smart Cube App to turn on/off the device.

• Follow the steps shown to remove the side and top decorative cover, and press the ON/OFF switch button.

Tips

• Press and hold for more than 3s to turn on or off the power; an interval of more than 10s is needed between power-on and power-off.

Tips

• In case of prolonged inactivity of the equipment (such as being offline for several consecutive days or having minimal operational hours), the system will issue a reminder. If no feedback is received from you, the equipment will be automatically turned off as a precautionary measure for safety. To resume operation of the equipment, please reach out to us for further instructions.

Low SOC

• The self-discharge characteristic of battery pack willl cause power loss. If the equipment is not charged for a long time, it may be damaged due to overdischarge of power. When the battery is low, charge the equipment in time.
• Under normal circumstances, the equipment can charge itself according to the running condition. If the equipment cannot be charged, please contact your sales agent in time and deal with it within the specified time. If the battery capacity is lost or irreversible damage is caused due to the delay, the product will not considered in warranty.
• When the battery power is greater than or equal to 10%, charge within 30 days
• When the battery power is less than or equal to 0% and less than 10%, charge within 7 days

Scenarios that may cause a charge failure (including but not limited to)

• The PV side has no input, and the power grid side is powered off for a long time
• The equipment is faulty
• Parameters are not set correctly

Emergency Treatment

Emergency Measures for Fire
