For solar installers, distributors and project developers looking for solar panels with battery storage for home applications, this battery offers a substantial storage capacity in a single unit, with the option to connect up to 16 compatible battery units in parallel.
A Home Solar Battery Designed Around Practical Storage Needs
Store More of Your Solar Energy
A home battery can store surplus electricity generated during the day for later use, depending on the configuration of the complete solar energy system. With 16.0768kWh nominal energy, the ECO-314L-(ST) provides a substantial storage base for residential solar projects and other applications that require battery-based energy storage.
Actual usable energy and backup duration depend on the system settings, inverter, connected loads and operating conditions.
Battery Management and Protection
The built-in BMS monitors battery voltage and temperature, supports cell balancing and provides configurable protection functions. The system also records up to 500 historical fault records, helping technicians review battery events during inspection and troubleshooting.
According to the product specification, the BMS includes battery-temperature sensors, an ambient-temperature sensor and a MOS temperature sensor.
Flexible Capacity Expansion
For projects requiring additional storage, up to 16 compatible units can be connected in parallel, subject to system design and the applicable installation requirements.
Battery units must not be connected in series or mixed with batteries from other brands or models. Before installation, confirm that the inverter, communication protocol, current limits and system settings are suitable for the proposed battery configuration.
Communication for System Integration
The ECO-314L-(ST) supports CAN and RS485 communication. These interfaces can be used for integration with compatible equipment, but compatibility should be confirmed against the specific inverter or energy management system before an order is placed.

Where This Battery Can Be Used
The ECO-314L-(ST) can be considered for projects such as:
Residential solar energy storage: storing solar-generated electricity for use later in the day, subject to the complete system design.
Home backup power systems: supporting selected household loads when the inverter and overall system are configured for backup operation.
Residential energy storage installations: providing a 51.2V battery platform for installers integrating compatible power conversion and monitoring equipment.
Small-scale energy storage projects: serving applications where the nominal capacity, current limits and environmental requirements match the project specification.
The final application should be assessed against the required load, inverter ratings, installation environment and local electrical requirements.
Installation and Operating Requirements
Correct installation is important for battery performance and service life. The ECO-314L-(ST) has an IP20 enclosure rating and should be installed in a dry, ventilated location protected from rain and direct water exposure.
Install the battery on a level, non-flammable surface, allow sufficient space for heat dissipation and do not stack the units in multiple layers. Keep the battery switched off when connecting the power harness, and follow the approved installation instructions.
Before connecting the battery to a solar inverter, check the DC voltage range, charging and discharging current limits, CAN or RS485 communication requirements and the inverter manufacturer's compatibility guidance.
FAQ
1. What battery do I need for solar panels with battery storage for home?
The appropriate battery depends on household electricity consumption, the amount of solar energy generated, the loads you want to support and the required backup duration. The ECO-314L-(ST) has 16.0768kWh nominal energy and a 51.2V nominal voltage. A system designer should confirm whether its capacity and current ratings suit your installation.
2. Does the 16.07kWh rating mean all of that energy is available to use?
No. The 16.0768kWh figure is the battery's nominal energy rating. Usable energy depends on operating limits, system settings and the connected equipment. It should not automatically be treated as the amount of electricity available to the loads.
3. Can I connect this battery to my existing solar inverter?
Compatibility depends on the inverter's supported battery voltage, charge and discharge current limits, communication protocol and configuration. The battery supports CAN and RS485, but these interfaces alone do not guarantee compatibility with every inverter. Confirm the exact inverter model before ordering.
4. Can I connect several batteries to increase storage capacity?
Yes. The specification permits up to 16 compatible units in parallel. Series connection is prohibited, and batteries from other brands or models must not be mixed into the same configuration. The complete system design must also account for current limits, cabling and inverter capacity.
5. Can this battery be installed outdoors?
The specified enclosure rating is IP20, so the battery is not designed for direct exposure to rain or water. Install it in a dry, ventilated and suitable protected location that meets the product's installation requirements.
6. What is the cycle life of the ECO-314L-(ST)?
The specification states 8,000 cycles under test conditions of 25°C, 100A charge/discharge current and 70% DOD. This is a result under the stated conditions, not a guarantee that every installation will achieve the same cycle count.
