SG48100P · Buyer decision facts
SunGoldPower SG48100P | 5.12kWh Rack Battery
The SG48100P is a 51.2V, 100Ah rack-format LiFePO4 battery with 5.12kWh nominal energy and a 100A BMS rating. Plan the inverter’s peak DC current and cabinet dimensions before adding modules.
The rack case is approximately 19.3 × 18.9 × 5.5 in and 93 lb. The battery lists CAN/RS485/RS232 communication, but exact inverter firmware and cable protocol must be confirmed; a matching 48V label is insufficient.
For wall mounting, compare the SG48100M wall battery.
Solar-ready capacity
A strong choice for storing daytime solar production and using that power later when the system needs it most.
Clean rack layout
Designed for organized energy storage builds where multiple batteries may be installed together.
Reliable storage for serious energy use
Battery storage is the foundation of any serious backup or off-grid system. This model is built for customers who want usable capacity, cleaner storage, and a battery format that can support solar charging and daily energy demands.
- Stores solar or grid-charged energy for later use when your system needs it.
- Rack-friendly format keeps larger storage systems cleaner and easier to expand.
- A strong fit for backup power, off-grid systems, RVs, marine use, cabins, and energy storage projects.
- Designed to support deeper cycling and cleaner long-term performance than older battery chemistries.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
What installation is the SG48100P's server-rack format intended for?
The server-rack format is intended for the mounting and service approach shown in the exact product documentation. Preserve required clearances, structural support, terminal protection, ventilation, environmental limits, and safe access for disconnecting the battery.
How should the SG48100P communicate with a compatible inverter?
Use only the communication protocol, cable, pinout, and inverter profile documented for this exact battery. Matching voltage is not enough; an unsupported communications connection can leave the inverter using incorrect charge and discharge limits.
What must match before adding another battery beside the SG48100P?
Use only connection arrangements explicitly approved for SG48100P. Match model, capacity, age, firmware, and state of charge; then use balanced busbars or equal-length conductors, individual protection where required, and the documented communication topology.
How do I check whether the SG48100P can start my largest motor load?
Capacity describes stored energy, not maximum power. Compare the inverter's continuous and surge DC current with the battery BMS, terminal, cable, fuse, and parallel-bank limits; voltage sag, temperature, and state of charge can trigger protection earlier.
Can a lead-acid charging profile be reused for the SG48100P?
Use the exact model's permitted charge voltage, current, temperature range, low-temperature behavior, and communication profile. Disable lead-acid features that the manual does not allow, coordinate every charging source, and never exceed the BMS or cell limits.
