Its combination of LiFePO4 chemistry, protective functions, and long cycle-life rating makes it useful for homeowners and installers evaluating a compact energy storage system.

Key Features and Buyer Benefits

LiFePO4 Lithium Iron Phosphate Technology

The battery uses lithium iron phosphate (LiFePO4) chemistry, which offers good thermal stability and is widely used for rechargeable solar energy storage.

As a result, LiFePO4 chemistry is a practical choice for systems that charge and discharge regularly.

1.28kWh Energy Storage Capacity

The SolarMax battery delivers 1.28kWh of nominal energy with a 100Ah capacity at 12.8V.

For example, this capacity provides a starting point when sizing backup for suitable lighting, fans, and other modest electrical loads.

Long Cycle Life

The battery has a cycle-life rating of at least 6,000 cycles at 80% depth of discharge.

However, actual operating life depends on usage, temperature, charging conditions, and other factors. Buyers should therefore treat the stated cycle-life rating as a test-based benchmark, not a guaranteed lifespan.

Bluetooth Battery Monitoring

Built-in Bluetooth monitoring lets customers check battery information through the supported monitoring interface.

Consequently, users can check monitoring information without relying only on an external voltage reading.

Built-In Battery Protection

The battery includes protection against overcharging, overdischarging, short circuits, overloads, and excessive temperature.

These protective functions help manage abnormal electrical conditions. Nevertheless, installers still need proper fuses, wiring, isolation, and compatible charging equipment.

Flexible Installation and Expansion

The metal enclosure supports wall-mounted and floor-standing installation.

Installers can connect up to four battery units in a supported series or parallel arrangement. However, each installation must respect the battery voltage, current limits, and permitted connection method.

Best For

The SolarMax 12.8V 100Ah battery is a practical choice for:

• Small solar energy storage systems using compatible battery charging equipment.
• Home backup arrangements with appropriately sized electrical loads.
• Users seeking a rechargeable LiFePO4 alternative to conventional battery technology.
• Installers requiring compact wall-mounted or floor-standing energy storage.
• Customers planning battery expansion using approved series or parallel configurations.

Not Ideal For

On the other hand, this battery may not suit applications requiring more stored energy or discharge power than a single 1.28kWh unit can provide.

Never connect one 12.8V unit directly to an incompatible 24V, 48V, or high-voltage battery input. Instead, verify the approved series configuration and charger requirements before installation.

It is also unsuitable for systems whose charging voltage, charging current, discharge demand, or environmental conditions exceed its operating limits.

Battery Capacity: kWh, Ah and Usable Energy Explained

Battery capacity is commonly expressed in ampere-hours (Ah), while stored energy is expressed in kilowatt-hours (kWh).

For customers asking how many kwh does a battery hold, the battery voltage and ampere-hour rating provide the nominal energy calculation.

The basic method to convert battery ah to kwh is:

Nominal Energy (kWh) = Voltage × Capacity (Ah) ÷ 1000

For this SolarMax battery:

12.8V × 100Ah ÷ 1000 = 1.28kWh

In other words, 1.28kWh represents nominal battery energy, not a promise that connected appliances can use the entire amount.

Usable energy depends on the selected discharge depth, inverter losses, operating conditions, and battery protection limits.

Customers asking how do i convert kwh to amp hours can use:

Capacity (Ah) = Energy (kWh) × 1000 ÷ Battery Voltage

Thus, these calculations help customers compare battery ratings without treating Ah and kWh as interchangeable.

Battery Chemistry and Cycle Life

The SolarMax SM-LFP-12100 uses lithium iron phosphate chemistry with a cycle-life rating of at least 6,000 cycles at 80% DoD.

For clarity, depth of discharge describes how much stored energy leaves the battery during a discharge cycle.

For example, 80% of the battery’s 1.28kWh nominal capacity equals approximately 1.024kWh of energy discharged from the battery. This is an illustrative calculation, not a guaranteed AC energy output.

Real-world battery life depends on the number of cycles, temperature, charge and discharge currents, storage conditions, and maintenance of correct system settings.

Battery Management System and Safety

The SolarMax battery includes multiple electrical protection functions for safer operation.

Protection features include:

• Overcharging protection
• Overdischarging protection
• Short-circuit protection
• Overload protection
• Overtemperature protection

Even so, these functions do not replace correctly rated DC protection devices or proper installation practices.

Use compatible charging equipment and confirm any required system-level communication before connecting the battery to a hybrid inverter.

Charging and Discharging Performance

The SM-LFP-12100 has a charging voltage of 14.2V and a recommended charging current of 20A.

Its maximum charging current is 100A, while the recommended discharge current is 50A and the maximum discharge current is 100A.

Meanwhile, its 10.0V discharge cut-off defines the lower voltage limit for discharge.

The charge efficiency is at least 97%, while discharge efficiency is at least 98%, under the applicable rating conditions.

Therefore, correct current settings are important. Customers researching solarmax battery setting should check their exact inverter or charger configuration before applying battery parameters.

Inverter Compatibility

The SolarMax battery is intended for compatible solar inverter and battery charging systems.

Its 12.8V nominal voltage must be matched with the actual operating voltage and charging requirements of the system.

First, check the inverter’s supported battery voltage, charge voltage, charging current, discharge demand, and communication requirements.

Furthermore, matching voltage alone does not establish complete inverter compatibility. Buyers can review solar inverter options and ask Hajvery Solar to check their inverter model before purchase.

Parallel Expansion

The SM-LFP-12100 supports series and parallel battery arrangements involving up to four units.

A suitable parallel arrangement can increase nominal energy capacity while maintaining nominal system voltage. A supported series arrangement can increase nominal system voltage.

For that reason, expansion requires correct battery matching, DC protection, cabling, and charger configuration.

Do not assume that every inverter supports every four-battery arrangement. Final compatibility and connection requirements must be checked before installation.

Technical Specifications

SolarMax 1.28kWh Lithium Battery Backup Time

The 1.28 kwh lithium battery backup time depends on the connected load, depth of discharge, inverter efficiency, and operating conditions.

For illustration, the following estimates assume 80% of nominal battery energy is discharged and a connected inverter operates at 90% efficiency.

Estimated AC energy available:

1.28kWh × 80% × 90% = 0.9216kWh

However, these figures are calculated estimates, not guaranteed runtimes. Actual results vary with battery condition, inverter efficiency, temperature, and load changes.

The lithium battery backup time formula used for the table is:

Estimated Backup Hours = Usable AC Energy (Wh) ÷ Average Load (W)

Customers comparing 100ah battery power backup time should also remember that batteries with identical Ah ratings can store different amounts of energy when their nominal voltages differ.
