The modular design allows up to 16 units to be connected in parallel, enabling flexible capacity expansion for various project scales.

Equipped with an intelligent BMS supporting CAN and RS485 communication, it is compatible with most hybrid inverters on the market. Whether for daily self-consumption, emergency backup, or complete off-grid living, the KTA battery delivers reliable and efficient energy storage.

Key Features

1. High Safety

The 51.2V 314Ah LiFePO4 Battery Pack uses lithium iron phosphate cell material and has passed multiple compliance certifications such as IEC62619, UN38.3, and CE. It is equipped with a 200A circuit breaker and will not have a risk of thermal runaway during use. It is suitable for various electrical energy storage scenarios.

2. Long Cycle Life

The charge and discharge cycle times at 25°C are ≥ 6000 times; the capacity loss is ≤ 3% (25°C, 20% SOC).

3. Wide Temperature Range

The charging temperature range is 0 to 40 degrees Celsius, and the discharge can be performed in an environment ranging from -20 to 40 degrees Celsius. It can be used normally in different climate regions.

4. Flexible Parallel Connection

A single battery model supports up to 16 parallel combinations, allowing for the expansion of energy storage capacity as needed. It can be easily extended to over 257 kilowatt-hours and can meet the energy storage requirements for various projects of different scales.

5. Intelligent Battery Management System

The independently developed battery management system has pre-charging and balancing functions; it supports remote data viewing and firmware upgrades.

Equipped with the self-developed battery management system, it has pre-charging and cell balancing functions, supports CAN and RS485 communication, and can remotely view data and upgrade programs. Most of the hybrid inverters on the market can be matched and connected, and the installation and wiring are simple and convenient.

6. Wide Compatibility

Suitable for most hybrid power and battery-type inverters; plug-and-play, easy installation.

Product Parameter

Product Applications

1. Household solar energy storage system, daily storing the electricity generated by photovoltaic power to meet the daily electricity consumption of the household.

2. Emergency backup power supply for home during power outages, ensuring the normal operation of household appliances and lighting equipment in case of sudden power failure.

3. Stable supply of basic electricity for off-grid power supply locations such as outdoor cabins, remote farms, and communication base stations.

4. Industrial and commercial energy storage projects, multiple units connected in parallel for expansion use, suitable for the energy storage needs of small and medium-sized industrial and commercial power supply.

Why the 314Ah Model?

While the 100Ah model (5.12 kWh) serves as an entry-level solution and the 200Ah model (10.24 kWh) addresses standard whole-home needs, the 314Ah model (16.08 kWh) occupies a distinct position in our lineup:

Why 314Ah Specifically?

1.One unit = a full day's power for a typical 4-person household (excluding electric heating). With 16.08 kWh, you can run refrigeration, lighting, entertainment, cooking appliances, and multiple device charging simultaneously without drawing from the grid.

2.Fewer units to reach high capacity: To achieve 80 kWh of storage, you need:

100Ah model: 16 units

200Ah model: 8 units

314Ah model: only 5 units → lower installation cost, less wall space, simpler cabling

3.Commercially viable as a standalone: At 16 kWh, a single unit can power small retail POS systems, telecom backup, or off-grid farm operations without requiring parallel configuration.

FAQ

1.Can this type of battery be used in parallel by multiple units?

The 51.2V 314Ah LiFePO4 Battery Pack supports up to 16 devices connected in parallel, and can flexibly expand the energy storage capacity according to the actual power consumption scale to meet the power supply requirements of different power levels.

2. What is the typical cycle life of the battery?

Under normal temperature (25℃) and 80% discharge depth conditions, the battery can achieve 6,000 cycles of use. It has low capacity loss during long-term use and a long service life.

3. Can it be used normally in both high and low temperature environments?

The charging temperature range is 0℃ - 40℃, and the discharge operating temperature range is -20℃ - 40℃. It can operate stably in various climate conditions such as temperate and subtropical regions.

4. Can I mix 314Ah units with 100Ah or 200Ah units in parallel?

No. Different capacity models must not be connected in parallel. The BMS will detect capacity mismatch and trigger a protection fault. All units in a parallel bank must be of the same model and same capacity.
