10kWh Battery for Home with Deye Inverter Installed in Mongolia

GSL ENERGY has completed another residential energy storage installation in Mongolia, combining a 10kWh battery for home use with a Deye hybrid inverter. In this project, the battery was installed indoors and positioned against the wall, providing a space-efficient energy storage solution without requiring a dedicated battery rack.

The battery supports several installation methods, including wall-mounted, floor-standing against a wall and rack-mounted configurations. This flexibility allows solar installers to select a suitable arrangement according to the available space, wall structure, equipment-room layout, and maintenance requirements.

Mongolia Residential Battery Project

Why Choose a 10kWh Home Battery?

A 10 kilowatt-hour battery offers a practical amount of energy storage for households with moderate daily electricity consumption. It can store surplus solar electricity generated during the day and make that energy available in the evening, at night or during a grid interruption.

Compared with a smaller battery, a 10 kWh home battery can support more household loads or provide a longer backup period. It is suitable for homes that need to operate selected equipment such as lighting, refrigeration, internet devices, televisions, computers and other essential appliances.

Actual backup duration depends on several factors:

• Usable battery capacity
• Battery state of charge
• Inverter conversion efficiency
• Combined power demand of connected loads
• Battery discharge settings
• Operating temperature

The battery should therefore be selected according to the household load profile rather than capacity alone.

Flexible Wall, Floor and Rack Installation

The battery used in this project was placed on the floor and positioned against the wall. This arrangement provided stable support while keeping the installation area organised and accessible.

The same battery design supports three common installation methods:

Wall-Mounted Installation

Wall mounting keeps the battery above the floor and helps preserve usable floor space. Before installation, the installer must confirm that the wall structure and mounting hardware can safely support the battery weight.

Floor-Standing Against the Wall

A floor-standing configuration places the battery close to the wall without transferring its full weight to the building structure. This method is suitable for utility rooms, garages, and other indoor areas with adequate floor space.

Rack-Mounted Installation

Rack installation can be used when batteries need to be integrated into an organised equipment cabinet or expanded into a larger lithium battery bank. It provides structured cable management and convenient access for inspection and maintenance.

Supporting multiple installation methods allows distributors and installers to use the same 10kWh solar battery across different residential layouts.

Integration with the Deye Hybrid Inverter

The battery was paired with a Deye hybrid inverter to manage energy flow between the solar panels, household loads, utility grid and battery storage system.

Communication between the battery management system and the inverter allows operating information such as voltage, current, state of charge, and protection status to be monitored. The installer must correctly configure the communication protocol, charging current, discharge limits, and battery operating parameters before commissioning.

System compatibility should be confirmed according to the exact battery and inverter models. Voltage range, maximum current and CAN or RS485 communication requirements must match.

How Does the 10kWh Solar Battery Operate?

During periods of solar generation, the Deye inverter supplies household loads and directs available surplus electricity to the battery. When solar production decreases, stored battery energy can be used to support the home.

Depending on the selected operating mode, the system may be configured for:

• Increasing solar self-consumption
• Reducing grid electricity use
• Providing backup power during outages
• Charging during lower-tariff periods
• Discharging during higher-tariff periods
• Maintaining a reserve state of charge for emergencies

The final operating strategy should be based on the homeowner's electricity consumption, local tariff structure and grid conditions.

How Long Can 10kWh Battery Backup Last?

The duration of 10kWh battery backup depends primarily on the power demand of the connected appliances. A lower essential-load demand will provide a longer backup period, while electric heaters, water pumps, air conditioners and other high-power equipment will consume the stored energy more quickly.

Backup time can be estimated with the following basic calculation:

Estimated backup time = usable battery energy ÷ total operating load

Usable energy may be lower than nominal battery capacity because of the permitted depth of discharge, inverter efficiency and system protection settings. A professional load assessment should therefore be completed before confirming the expected backup duration.

Can a 10kWh Battery Be Used with a 10kW Solar System?

A 10kWh battery can be paired with a 10kW solar system, provided that the inverter, battery voltage, charging current, and communication protocol are compatible.

However, 10kW and 10kWh describe different system characteristics:

10kW refers to the power rating of the solar array or inverter.

10kWh refers to the amount of energy stored in the battery.

Battery capacity should not automatically be matched to solar-array power on a one-to-one basis. The appropriate battery size depends on daily solar generation, household consumption, evening loads, and required backup duration.

What Affects a 10kW Solar System with Battery Price?

When evaluating a 10 kW solar system with battery price, buyers should consider the complete system configuration rather than the battery capacity alone.

The final project cost may be affected by:

• Solar-panel brand and total array capacity
• Hybrid inverter model and output power
• Battery chemistry and usable capacity
• Required backup loads
• Number of battery modules
• Mounting method and accessories
• Electrical protection equipment
• Cable length and installation conditions
• Transportation and local installation costs
• Monitoring and communication requirements

For an accurate quotation, the supplier should review the project location, load profile, solar-array design, grid voltage and required backup time.

Installation Considerations in Mongolia

Because Mongolia experiences long and extremely cold winters, residential batteries should be installed in a protected indoor environment that remains within the manufacturer’s permitted operating temperature range.

The installation location should provide:

• Protection from rain, snow and direct moisture
• Suitable indoor temperature conditions
• Adequate ventilation
• Sufficient maintenance clearance
• Stable wall or floor support
• Appropriate electrical protection
• Accessible emergency isolation

If the indoor temperature may fall below the permitted charging range, insulation, heating or a temperature-controlled installation area may be required.

Benefits of This 10kWh Battery Installation

This residential project provides several operational and installation benefits:

• Stores surplus solar electricity for later use
• Provides backup power for selected household loads
• Improves residential solar self-consumption
• Integrates with a Deye hybrid inverter
• Supports wall-mounted installation
• Supports floor-standing installation against a wall
• Supports rack-mounted deployment
• Adapts to different residential spaces
• Allows future battery-bank expansion where supported
• Uses LiFePO4 chemistry for residential energy storage

A Flexible 10kWh Battery Solution for Residential Projects

This Mongolia installation demonstrates how a 10kWh battery can provide both energy storage and installation flexibility. Positioning the battery against the wall helped the installer use the available indoor space effectively while maintaining access for system inspection and maintenance.

The option to install the battery on a wall, against a wall, or inside a rack makes it suitable for different home energy storage projects. Combined with a compatible Deye hybrid inverter, the system provides a practical solution for solar self-consumption and residential battery backup.
