Key Features and Buyer Benefits

LiFePO4 Battery Technology

The battery uses lithium iron phosphate (LiFePO4) chemistry, which is widely used for rechargeable stationary energy storage.

LiFePO4 technology offers good thermal stability and long cycle-life potential when operated within the battery’s electrical and environmental limits.

Its integrated battery pack construction helps reduce internal line losses while improving energy density.

11.8kWh Energy Storage with 230Ah Capacity

The combination of 51.2V and 230Ah provides a nominal energy capacity of 11.8kWh.

This makes the battery suitable for applications where a smaller storage unit may require frequent recharging or where customers want additional stored energy for evening and overnight consumption.

Actual backup duration depends on inverter efficiency, connected loads, battery condition, and operating conditions.

Advanced BMS Protection

An advanced Battery Management System monitors and manages battery operation.

The battery includes an active fuse as part of its protection architecture, helping manage electrical safety within the battery system.

Its protective design works alongside the battery’s operating limits and recommended installation practices.

Smart Monitoring and Communication

The battery includes CAN 2.0, RS485, and Bluetooth connectivity with app support.

Its LED indicators display battery state of charge, working status, and protection status. A buzzer provides an additional status indication.

These functions help installers and users monitor battery operation and identify relevant operating conditions.

Flexible Installation Options

The Inverex INV-LV-IP21 11.8 supports wall-mounted, floor-mounted, and stack-mounted installation.

Automatic networking removes the need for manual DIP-switch configuration, simplifying battery networking during supported installations.

The battery also supports expansion through compatible parallel configurations.

Best For

The Inverex 11.8kWh Lithium Battery is particularly suitable for:

• Residential hybrid solar systems requiring additional stored energy.
• Homes experiencing regular electricity load shedding.
• Commercial locations with selected essential backup loads.
• Customers planning expandable low-voltage energy storage.
• Solar installations requiring BMS communication and monitoring.

The final battery and inverter combination should be selected according to the actual load profile and verified compatibility.

Not Ideal For

This battery may not suit every installation.

It is not intended for high-voltage battery systems that require a different battery architecture.

Its IP21 enclosure also makes it unsuitable for locations exposed directly to rain, water spray, or demanding outdoor conditions.

Users requiring an immediately compatible battery for an existing inverter should confirm the inverter’s operating voltage, BMS protocol, firmware, and charging limits before ordering.

Battery Capacity: kWh, Ah and Usable Energy Explained

Understanding battery ah vs kwh is important when comparing solar batteries.

Ampere-hours (Ah) describe electrical charge capacity, while kilowatt-hours (kWh) describe the amount of energy a battery can store.

To convert battery ah to kwh, use:

Nominal Voltage × Ampere-hours ÷ 1,000 = Nominal Energy in kWh

For this Inverex battery:

51.2V × 230Ah ÷ 1,000 = 11.776kWh

The battery’s rated nominal energy is 11.8kWh.

A common buyer question is how many kwh does a battery hold. The answer depends on its nominal voltage and capacity, rather than its Ah rating alone.

Recommended Usable Energy

The battery has a recommended depth of discharge of 90%.

Based on its rated nominal energy:

11.8kWh × 90% = approximately 10.62kWh

This is a calculated battery-side energy estimate before inverter conversion losses, operating restrictions, and other real-world factors.

It should not be treated as guaranteed usable AC energy.

Battery Chemistry and Cycle Life

The Inverex INV-LV-IP21 11.8 uses LiFePO4 chemistry and has a rated cycle life of at least 6,000 cycles under the specified 25°C ± 2°C test reference and 70% end-of-life capacity criterion.

A battery cycle refers to a charge-and-discharge process. Actual lifetime depends on factors such as discharge depth, temperature, charging behaviour, and operating conditions.

The recommended 90% DoD is a useful operating guideline, but it should not be interpreted as a guarantee of 6,000 cycles under every usage pattern.

Proper inverter charging settings and suitable temperature conditions are important for long-term battery operation.

Battery Management System and Safety

The Inverex battery integrates an advanced BMS with an active fuse.

The BMS helps coordinate battery operation, while status indicators provide information about state of charge, active operation, and protection conditions.

The battery also uses natural cooling.

For safe use, installation should follow the required electrical limits, approved battery connections, suitable protection devices, and appropriate environmental conditions.

Only suitably qualified installers should configure high-current battery connections.

Charging and Discharging Performance

The INV-LV-IP21 11.8 supports the following electrical limits:

These ratings provide useful operating flexibility for compatible energy storage systems.

The 280A peak current is a short-duration limit and should not be treated as the battery’s continuous operating current.

Available charging and discharging current can vary with temperature and state of charge. Final inverter settings should respect the battery’s operating limits.

Inverter Compatibility

The Inverex INV-LV-IP21 11.8 is designed for compatible low-voltage energy storage applications.

It operates at a nominal voltage of 51.2V and supports CAN 2.0 and RS485 communication.

Before selecting an inverter, verify:

• Supported battery voltage range.
• Battery communication protocol and firmware.
• Maximum charging and discharging current.
• Correct communication cable and connection arrangement.
• Battery configuration and operating parameters.

Voltage compatibility alone does not establish complete inverter compatibility.

Hajvery Solar Energy can assist customers with compatibility checks before purchase. Explore our Solar Inverters page and verify exact inverter support before buying.

Parallel Expansion

The battery supports up to 32 units in parallel within an appropriately designed system.

This provides an expansion path for customers who need additional energy storage beyond a single battery.

Parallel installation requires suitable battery connections, supported communication arrangements, properly sized cables, protection devices, and compatible inverter settings.

The actual supported configuration should be established before installation rather than assuming every inverter can operate with the maximum number of batteries.

Technical Specifications

Estimated Backup Time

Backup duration depends on the available energy, inverter conversion efficiency, connected loads, and battery operating conditions.

For illustration, the following estimates assume:

• Nominal energy: 11.8kWh
• Battery depth of discharge: 90%
• Inverter conversion efficiency: 90% (illustrative assumption)
• Constant average AC load

Estimated AC energy:

11.8 × 0.90 × 0.90 = approximately 9.56kWh

These are calculated examples, not guaranteed backup durations. They do not confirm that a particular inverter or installation can safely deliver every example load.

Real battery runtime can be shorter due to inverter standby consumption, changing loads, temperature, battery aging, and operational cutoffs.

Lithium Battery Use in Pakistan

For homes and businesses in Pakistan, battery storage can help shift stored solar energy into evening hours and provide electricity during load shedding when connected through a compatible backup-capable inverter.

The Inverex 11.8kWh battery’s energy capacity can support planning for longer backup periods, but the actual duration depends on electricity consumption.

Installation conditions are particularly important during Pakistan’s hot summer months.

The battery has an IP21 enclosure rating and should be installed in a suitable protected location with adequate ventilation.

Charging is rated from 0°C to 55°C, while discharging is rated from -20°C to 55°C.

Avoid direct water exposure, excessive environmental heat, and installations that obstruct required ventilation or maintenance access.
