Meet the SG 48100M: Features That Matter
The SungoldPower SG 48100M isn’t just another solar battery; it packs serious performance:
- Battery Type: 48V, 100Ah lithium iron phosphate (LiFePO4)
- Capacity: 5,120 Wh
- Voltage: Nominal 51.2V
- Weight: A hefty 116 lbs
- Expandability: Connect up to 32 units in parallel
- Temperature Range: -4°F to 140°F (discharging)
- Warranty: 10 years
Its rugged build and ability to connect to various inverters (like EG4 6000XP and Lux Power) give it a wide user appeal. If you’re planning a large-scale solar storage system, the SG 48100M offers excellent scalability.

Installation Considerations: Get the Setup Right

Installing the SG 48100M might require more than just enthusiasm:
- Mounting the Battery: At 116 lbs, it’s best to have help lifting it onto the wall bracket.
- Clear Access Ports: Power and communication ports are located at the bottom.
- Connection Essentials:
- Positive/Negative leads for inverter and daisy-chaining
- RS485 and CAN communication ports
- Proper grounding is a must
Versatile Communication Protocols
One of the highlights of the SG 48100M is its ability to sync with a broad array of inverters. This is achieved through:

- RS485 & CAN Protocols: Compatible with Lux Power, EG4, Growatt, and more
- Customizable DIP Switch Settings: Set according to the battery’s position in the string
- Menu Navigation: Simple interface to configure battery type and protocol via inverter panel
These features ensure seamless integration, which is crucial for optimal power management and real-time battery monitoring.
Safety First: Wiring and Wall Material
When setting up your system, remember that safety is non-negotiable:
- Use Hardy Backer Board: Especially if mounting on combustible surfaces like OSB
- Conduit Requirements:
- Battery cables
- PV input lines
- Communication wires
- Ground Everything: Battery and inverter must be connected to earth ground
Although the setup shown was temporary, these best practices are critical for any permanent solar install.
Final Thoughts: Is It Worth It?
