SunGoldPower Powerwall X 51.2V 200AH Lithium Battery
Powerwall X 51.2V 200Ah LiFePO4 Battery
A high-capacity 10.24kWh lithium battery built for 48V solar storage, home backup, and larger off-grid power systems. The SG48200T combines LiFePO4 chemistry, touchscreen monitoring, smart BMS protection, inverter communication, and parallel expansion in a clean wall-mounted energy storage format.
Wall-mounted 48V energy storage
Designed for bigger solar storage and backup systems
The SG48200T Powerwall X is built for customers who need more than a small battery add-on. With 10.24kWh of storage in a single 51.2V battery, it gives home backup, off-grid, and solar energy systems a serious foundation without stacking multiple small batteries from day one.
Feature-rich battery platform
More than just storage capacity
For a battery this large, system visibility and protection matter. The SG48200T combines a touchscreen interface, smart BMS, communication ports, and a scalable battery architecture so it can serve as the heart of a more capable 48V power system.
- Large 10.24kWh battery capacity for longer runtime and better overnight storage.
- LCD monitoring gives easier access to battery status during setup and daily use.
- Smart BMS helps protect the battery from common electrical and temperature-related risks.
- RS485 / CAN communication supports integration with compatible inverter systems.
Built for outages and overnight power
Store solar energy for when you actually need it
The Powerwall X is designed to collect energy during the day and keep it ready for nighttime use, backup power, and emergency situations. That makes it a strong fit for customers who want a cleaner, quieter way to support essential loads when solar production drops or the grid goes down.
Expandable storage
Scale from one battery to a large storage bank
Start with one 10.24kWh battery for a clean 48V storage foundation, or expand into a much larger bank as power needs grow. SunGoldPower lists support for up to 32 units in parallel, giving properly designed systems room to scale far beyond a basic backup setup.
Start with 10.24kWh of storage
Use one Powerwall X as the foundation for a 48V home backup, solar storage, or off-grid system.
Add batteries as your system grows
Parallel additional units to increase available storage for longer outages, heavier loads, or more overnight energy use.
Scale up to high-capacity banks
SunGoldPower lists support for up to 32 units in parallel, allowing properly designed systems to scale to roughly 328kWh of total battery capacity.
Controls, terminals, and monitoring
Easy access to the information installers need
The Powerwall X keeps key terminals, communication ports, status indicators, and the LCD touch panel accessible for installation and system checks. It is designed to be easier to monitor than a sealed black-box battery tucked away in a utility room.
- LCD touch panel for real-time battery status visibility.
- Positive and negative terminals for high-current battery connections.
- Communication and link ports for supported multi-battery and inverter setups.
- Status indicators help with installation checks and basic troubleshooting.
Monitoring and communication
Designed to work inside smarter 48V systems
The SG48200T supports communication with compatible inverter systems and optional monitoring hardware, helping installers and owners keep better visibility into battery performance across one or multiple battery packs.
Quick battery checks from the front panel
The built-in LCD touch screen makes it easier to view essential battery information like state of charge, voltage, current, and operating status.
Monitoring support for multi-battery systems
SunGoldPower shows WiFi monitoring support for systems with multiple battery packs, helping simplify visibility across a larger storage bank.
RS485 / CAN support for compatible inverters
Communication support helps compatible inverters coordinate with the battery BMS for safer, more informed charging and discharging behavior.
One monitoring module for larger banks
Cleaner visibility across multiple battery packs
For larger installations, SunGoldPower shows the Powerwall X supporting multiple battery packs with a shared monitoring setup. That matters when the system grows beyond a single battery and you want cleaner visibility without overcomplicating the wall.
- Supports multi-battery layouts for larger storage projects.
- Designed around clean wall-mounted installation instead of scattered batteries.
- Useful for residential backup, small commercial, and off-grid solar storage systems.
- Confirm communication wiring, inverter settings, and monitoring accessories before installation.
Best-fit applications
A serious battery for backup, off-grid, and solar storage builds
The Powerwall X is best matched with properly designed 48V inverter/charger systems where higher storage capacity, system communication, and clean installation matter. It is a strong fit for customers building a larger battery bank instead of a small plug-and-play backup setup.
Backup energy for essential home loads
Store battery power for outages, nighttime use, and critical-load backup when paired with the right inverter and transfer setup.
Storage for cabins and off-grid systems
Use the 48V battery platform as the storage foundation for solar-powered cabins, workshops, remote homes, and off-grid projects.
Scalable storage for larger installs
Parallel expansion makes the SG48200T a practical choice for properly designed residential and light commercial storage systems.
Stored power when grid access is unreliable
Keep a high-capacity energy reserve available for blackouts, storm season, emergency backup, and solar production gaps.
