About GSL ENERGY
Founded in 2011, GSL ENERGY is a global leader in lithium battery manufacturing, specializing in residential, commercial, and industrial energy storage systems.
With a 15,000㎡ factory, 5.8GWh annual capacity, and UL, IEC, CE, and UN38.3 certified production, we offer OEM, ODM, and OBM services to global partners.
GSL ENERGY — Powering the World with Sustainable Energy Solutions.
The GSL ENERGY floor-standing home battery is available in two capacity configurations: 14.34kWh (51.2V 280Ah) and 16.07kWh (51.2V 314Ah).
The 14.34kWh model provides approximately 12.90kWh of recommended discharge energy at 90% DOD, while the 16.07kWh model provides approximately 14.47kWh.
These capacity options allow homeowners and solar installers to size the battery according to household electricity consumption, solar PV production, backup duration, and future expansion requirements.
The 14.34kWh GSL051280A-B-GBP2 configuration is listed with UL 1973 and UL 9540, together with CB-IEC62619, CE-EMC, MSDS, and UN38.3 documentation.
Certification can vary by model and system configuration. Installers, distributors, and project buyers should confirm the certification documentation for the exact battery and energy storage configuration required for their project before ordering.
UL 1973 covers batteries used in stationary and certain other applications, while UL 9540 applies to energy storage systems and equipment at the system level.
For residential battery projects in the United States and Canada, installers should verify the certification requirements for the specific battery, inverter, and complete energy storage system configuration.
Yes. This battery can be integrated into a whole-home battery backup system when paired with a compatible inverter and properly designed residential electrical system.
Battery capacity determines how much stored energy is available, while inverter power determines how much household load can be supplied at one time.
For whole-home backup, installers should evaluate HVAC equipment, refrigerators, water pumps, lighting, kitchen appliances, and other critical loads before selecting the final battery and inverter configuration.
Yes. The battery system supports up to 16 units in parallel, allowing storage capacity to be expanded for larger homes, villas, residential solar projects, and selected light-commercial applications.
For example, sixteen 14.34kWh batteries provide approximately 229kWh of nominal battery capacity.
Final system capacity should be confirmed according to the battery model, BMS architecture, inverter compatibility, cabling, and electrical protection design.
Yes. The scalable parallel architecture allows homeowners to start with a smaller battery system and add compatible batteries as electricity consumption, solar capacity, or backup requirements increase.
Before expanding an existing system, battery compatibility, BMS communication, inverter capacity, cabling, and installation requirements should be checked.
The nominal battery voltage is 51.2V, with an operating voltage range of approximately 46–56V.
It belongs to the 48V-class low-voltage residential energy storage category and is designed for use with compatible low-voltage hybrid and energy storage inverters.
The battery supports CAN 2.0 and RS485 communication for integration with compatible low-voltage residential energy storage inverters.
Before installation, confirm the inverter’s battery voltage range, maximum charge/discharge current, CAN or RS485 communication protocol, firmware version, and supported parallel battery configuration.
Compatibility should always be verified for the exact inverter model and firmware version.
Yes. The battery features an IP65-rated enclosure and is designed for suitable outdoor and ground-mounted residential energy storage installations.
Outdoor installations should still comply with the specified operating temperature range and applicable local electrical, fire safety, clearance, and environmental requirements.
The specified discharge temperature extends to approximately -20°C, while the specified charging temperature begins at approximately 0°C.
For colder U.S. states and Canadian regions, installers should consider winter ambient temperatures, installation location, and thermal protection when designing an outdoor battery storage system.
Both battery configurations specify a recommended charge/discharge current of approximately 150A, with a maximum current of 200A.
Actual operating current must also remain within the limits of the inverter, BMS, cables, protection devices, and complete electrical system design.
At the recommended 90% depth of discharge (DOD), the 14.34kWh model provides approximately 12.90kWh of recommended discharge energy, while the 16.07kWh configuration provides approximately 14.47kWh.
Actual usable energy can vary depending on SOC settings, inverter configuration, ambient temperature, household load, and operating strategy.
Backup duration depends primarily on household load.
For example, if backed-up loads average approximately 1kW, around 13–14.5kWh of available battery energy could theoretically support that average load for roughly 13–14.5 hours before accounting for inverter losses and operating reserves.
If average consumption increases to 2kW, the theoretical runtime would be approximately half as long.
For accurate whole-home battery sizing, installers should calculate backup requirements using the home’s actual load profile.
Yes. When paired with a compatible hybrid or solar-storage inverter, the battery can store excess solar energy generated during the day and make it available when needed.
Typical applications include solar self-consumption, home battery backup, off-grid solar systems, and time-of-use energy management.
Yes. The battery supports WiFi monitoring, together with CAN 2.0 and RS485 communication.
This allows battery operating information and system status to be monitored within a compatible residential energy storage system.
