SGH48100T Server Rack 48V 100AH Lithium Battery Self-Heating - 1 Battery
SGH48100T 48V 100Ah Self-Heating LiFePO4 Battery
A rack-mount 48V lithium battery built for home energy storage, off-grid solar, and backup power systems that need dependable performance in colder conditions. The SGH48100T combines a self-heating system, smart BMS protection, inverter communication, and scalable parallel expansion in a compact 3U server rack format.
Rack-mount lithium storage for real backup systems
Built for scalable 48V energy storage
The SGH48100T is designed around a compact 3U server rack form factor, making it easier to build a clean 48V battery bank for home backup, off-grid cabins, solar storage, and small commercial power systems. Start with one 5.12kWh battery and expand the system as your power needs grow.
Cold-weather charging support
Self-heating protection for winter energy storage
Cold weather is one of the biggest challenges for lithium battery charging. The SGH48100T includes an automatic self-heating function designed to activate in low temperatures and bring the battery up to a safer charging range before normal charging continues.
- Designed for low-temperature energy storage applications.
- Automatic heating helps protect the battery during winter charging conditions.
- Useful for cabins, backup systems, and off-grid installs in colder climates.
- Pair with a compatible 48V inverter/charger and follow the manual for cold-weather settings.
Wider operating temperature range
Ready for harsher storage environments
SunGoldPower positions this model for low-temperature zones where a standard rack battery may be harder to keep charged. The self-heating system is built to help the battery prepare itself for charging when surrounding temperatures drop.
Expandable 48V battery bank
Scale from one battery to a larger storage system
For customers building a serious solar battery bank, the SGH48100T can be paralleled with additional units. That makes it a strong fit when you want to start with one 5.12kWh module and grow into a larger 48V home backup or off-grid storage system.
Start with one 5.12kWh module
Use one SGH48100T as the foundation for a compact 48V backup or solar storage system where rack-mount organization matters.
Add capacity as your system grows
Parallel additional batteries to increase available storage for longer backup runtime, overnight loads, or larger solar charging systems.
Built for high-capacity banks
SunGoldPower lists support for up to 32 batteries in parallel, allowing properly designed systems to scale into much larger storage banks.
Communication for inverter integration
Designed to work with compatible inverter systems
The SGH48100T supports RS485 and CAN Bus communication, helping compatible inverters read battery information and coordinate charging/discharging behavior. That matters for modern 48V systems where the battery and inverter need to communicate clearly.
- RS485 / CAN communication support for compatible inverter systems.
- BMS communication helps the inverter understand battery state and protection limits.
- Useful for solar storage systems where battery visibility and system coordination are important.
- Always confirm inverter compatibility, protocol settings, and cable requirements before installation.
Smart BMS and connection layout
Clean front-panel access for a rack battery bank
The front-panel layout keeps key connection points, communication ports, status indicators, and terminals easy to access once the battery is installed in a rack or energy storage cabinet. Combined with the smart BMS, the SGH48100T is built for organized 48V battery system installs.
- Smart BMS protection against common battery safety issues.
- Front-access terminal and communication layout for cleaner installations.
- Status indicators make system checks easier during setup and maintenance.
- Rack format helps keep multi-battery systems neat and serviceable.
Common system applications
A practical battery for solar, backup, off-grid, and mobile power systems
SunGoldPower positions the SGH48100T for home energy storage, small commercial systems, PV storage, off-grid power systems, and RV-style energy setups. It is best matched with compatible 48V inverter/chargers and correctly sized solar charging equipment.
Backup power for essential home loads
Pair with a compatible inverter system to store energy for outages, nighttime use, and critical household backup needs.
Storage for cabins and off-grid systems
The 48V rack format is a strong fit for cabins, remote homes, workshops, and other off-grid projects that need organized battery storage.
Store solar energy for later use
Use the battery bank to capture PV production during the day and supply loads when solar production drops.
Useful for properly designed mobile systems
For RV or mobile applications, confirm rack mounting, ventilation, inverter compatibility, and safe installation requirements before purchase.
