Nimbess 14.3kW IP20 Lithium Battery

Nimbess 14.3kWh IP20 Lithium Battery Overview

The Nimbess 14.3kWh IP20 Lithium Battery is designed to store electrical energy for use when solar generation is low or the grid supply is unavailable. With 14.3kWh nominal energy, it provides a substantial storage capacity for compatible low-voltage solar systems.

Its 51.2V, 280Ah configuration uses Lithium Iron Phosphate (LiFePO4) cell technology. The battery has an 80% Depth of Discharge rating and supports a maximum discharge current of 200A. These characteristics make it important to match the battery with an inverter that can operate within its voltage, current and communication requirements.

The unit includes a touchscreen, circuit breaker and Wi-Fi app functionality. It also supports cloud-based monitoring and can be installed on the floor or mounted on a suitable wall.

Key Features and Buyer Benefits

LiFePO4 Battery Chemistry

This battery uses Lithium Iron Phosphate (LFP) cells. LiFePO4 is widely used in stationary energy storage because it offers a stable battery chemistry for repeated charging and discharging. Correct installation, suitable operating conditions and compatible charging settings remain important for long-term performance.

14.3kWh Energy Storage

The nominal energy capacity is 14.3kWh. This gives households and suitable commercial users a substantial energy reserve for backup applications. Actual backup duration depends on the connected load, inverter efficiency, battery condition and operating environment.

Wi-Fi App and Cloud Monitoring

The battery supports Wi-Fi app monitoring and cloud management. Users can access supported battery information through the monitoring system. The touchscreen also provides a local interface for viewing battery information.

Parallel Expansion

The system supports connecting up to 16 battery units in parallel. This allows a suitably designed energy storage installation to be expanded when additional capacity is required. Parallel installations must follow the manufacturer’s connection requirements and use compatible equipment.

Flexible Installation

The battery supports floor-standing and wall-mounted installation. The installer should select a suitable location with adequate structural support, ventilation and protection from unsuitable environmental conditions.

Best For

The Nimbess 14.3kWh battery may suit:

• Homes requiring higher-capacity solar energy storage.
• Hybrid solar systems designed for a 51.2V low-voltage battery.
• Users who want to store excess solar energy for later use.
• Installations requiring Wi-Fi-based battery monitoring.
• Residential or suitable commercial projects that may need parallel battery expansion.
• Users looking for LiFePO4 energy storage with a 5-Year Standard Warranty.

Not Ideal For

This battery may not be suitable for:

• High-voltage battery systems that cannot operate with a 51.2V battery.
• Inverters that do not support the battery’s voltage and communication requirements.
• Installations where the required continuous load exceeds the battery’s discharge limits.
• Outdoor locations exposed to rain, water or dust without suitable additional protection. Its IP20 rating is intended for indoor use in an appropriate protected environment.
• Installations that cannot meet the battery’s temperature and mounting requirements.

Battery Capacity: kWh, Ah and Usable Energy Explained

Battery capacity is commonly described using both kilowatt-hours (kWh) and ampere-hours (Ah). These values explain different aspects of a battery.

• kWh represents the amount of energy stored.
• Ah represents the battery’s electrical capacity.
• Voltage is required to understand how the ampere-hour rating relates to energy.

The Nimbess battery has a nominal voltage of 51.2V, a capacity of 280Ah and nominal energy of 14.3kWh.

Its specified Depth of Discharge is 80%. Based on that rating, the estimated battery-side usable energy is approximately 11.44kWh before inverter conversion losses and other system losses. Actual usable energy may vary with operating conditions. For company details, visit the official NIMBESS website.

Battery Chemistry and Cycle Life

The battery uses LiFePO4 (LFP) cell chemistry and has a cycle-life rating of more than 10,000 cycles.

The stated cycle-life test conditions are:

• Temperature: 25°C ± 2°C
• Charge/discharge rate: 0.35C
• Depth of Discharge: 80%
• End-of-life capacity reference: 65% EOL

Cycle life is a test-based rating, not a guarantee that every installation will achieve the same result. Charging settings, temperature, load profile, installation quality and battery operating conditions can affect service life.

Battery Management and Monitoring

The battery includes a battery management system (BMS) and a circuit breaker. Its monitoring functions include Wi-Fi app connectivity, cloud management and a touchscreen interface.

The BMS supports communication with compatible inverter systems. Before installation, the installer should verify the required battery voltage, communication protocol and inverter compatibility. Do not assume that every inverter model will communicate correctly without a model-specific compatibility check.

Charging and Discharging Performance

The battery has a standard charge voltage of 56.8V and a maximum discharge current of 200A. Its maximum charging and discharging rate is 0.7C.

The discharge cut-off voltage is 44.8V. Correct inverter settings are important to keep the battery operating within its specified limits. Charging and discharging should be configured by a qualified installer who can verify the inverter settings and battery communication.

Inverter Compatibility

The Nimbess battery is a 51.2V low-voltage battery. It supports RS485, CAN, USB and RS232 communication interfaces, and its BMS supports communication with multiple inverter brands.

However, communication ports alone do not guarantee compatibility with every inverter. Before purchasing, confirm the exact inverter model, supported battery protocol, voltage range, charging settings and discharge-current requirements.

Parallel Expansion

The battery supports parallel connection of up to 16 units. Parallel expansion can increase the total energy storage capacity of a correctly designed system.

Before adding batteries, confirm that the units meet the required connection conditions. The installer should follow the approved wiring arrangement, communication setup, protection requirements and commissioning procedure. Do not connect batteries with different specifications or operating conditions without confirming that the arrangement is permitted.

Technical Specifications

Estimated Backup Time

The battery’s backup duration depends on the connected load, inverter efficiency, battery condition and operating conditions. At 80% DoD, the estimated battery-side usable energy is approximately 11.44kWh.

The following figures are theoretical battery-side estimates before inverter conversion losses:

These values are estimates, not guaranteed backup times. Actual runtime will generally be lower after inverter losses and may change with load variation, temperature, battery condition and operating limits. High-starting-current appliances should be assessed separately.

Lithium Battery Use in Pakistan

In Pakistan, solar batteries are commonly used to store daytime solar generation for evening consumption and backup during grid outages. A suitable lithium battery can help households and businesses make better use of their solar energy.

When selecting a battery for a local installation, consider the expected load, required backup duration, inverter compatibility and installation environment. The Nimbess battery has an IP20 protection rating, so it should be installed indoors in a clean, dry and suitably protected location. Avoid exposure to rain, water and excessive dust.

High ambient temperatures can also affect battery operation. Keep the battery within its specified charging and discharging temperature ranges, and arrange installation through a qualified professional.
