HV Lithium Battery Storage: Modular, Expandable, and Surprisingly Easy to Move
Introduction
Most people think high-voltage Battery Storage is complicated:
- Heavy, fixed installations
- Difficult to expand later
- Requires professional re-wiring for every upgrade
We decided to build something different.
SUG NEW ENERGY CO., LTD. proudly presents the SBS-H High Voltage Rack Lithium Energy Storage Battery – a modular, scalable, and surprisingly mobile solution for homes, businesses, and industrial backup systems.
No more "buy once, cry once." No more being locked into a fixed capacity. Just stack, connect, and grow.
What Makes the SBS-H Different?
The SBS-H is not a single fixed battery. It is a building-block system based on 51.2V or 102.4V lithium iron phosphate (LiFePO₄) modules that can be connected in series to reach higher voltages and capacities.
At a glance:
| Feature | Benefit |
| 2–12 modules in series | Scale from 30 kWh to 122 kWh |
| High-voltage BMS | Safe management of series-connected strings |
| Grade A LiFePO₄ cells | >6000 cycles @ 80% DoD |
| Rack design with casters | Easy to move and reposition |
| CAN / RS485 communication | Seamless inverter integration |
| IP20 (indoor use) | Clean, protected installation |
Key Product Features
🔋 1. Grade A LiFePO₄ Cells
Only highest-quality cells. No recycled or lower-grade materials. This ensures consistent performance, long cycle life (>6000 cycles), and thermal stability.
📈 2. Supports 2–12 Modules in Series
Need more capacity? Add modules. Need higher voltage? Configure more modules in series. The system grows with your needs – from a small home backup to a large industrial storage.
🧠 3. High-Voltage BMS Control System
Series connections require advanced battery management. Our BMS monitors every module, balances cells, and communicates with your inverter via CAN or RS485.
🚚 4. Convenient to Move & Freely Combine
Each module is housed in a high-strength steel rack with wheels. You are not welding or bolting to the floor. Need to relocate? Roll it.
❄️ 5. Optional Air Conditioning Cooling
For hot environments or high-rate applications, an AC cooling option keeps the battery at optimal temperature – extending life and maintaining safety.

Application Areas
The SBS-H series is designed for high-voltage, high-capacity applications where reliability and scalability matter:
| Application | Why SBS-H Fits |
| Home energy storage | 30–60 kWh powers a large home through peak rates or outages |
| Small business / retail | 40–80 kWh keeps registers, fridges, and lights running |
| Telecommunications | High voltage reduces current and cable losses |
| Emergency lighting & UPS | Instant backup, clean DC power |
| Control & alarm systems | Reliable 24/7 power for critical infrastructure |
| Database & server rooms | Clean, regulated backup power |
| Fire protection systems | Always-ready emergency power |
Installation: What You Need to Know
The SBS-H is designed for professional installation by qualified electricians.
Basic requirements:
- Compatible high-voltage hybrid inverter (300–700V DC input range)
- CAN or RS485 communication (preferred for BMS integration)
- Adequate ventilation (IP20, indoor use only)
- Ambient temperature 0–45°C for best life
Not included (customer supplies):
- DC cables and breakers
- AC connection from inverter
- Rack anchoring (optional, for seismic zones)
Real-World Example
Scenario: A 4-bedroom home in California with:
- 8 kW solar array
- Time-of-use electricity rates (0.48/kWhpeak,0.48/kWhpeak,0.22/kWh off-peak)
- Frequent summer grid alerts
Solution: SBS-H-40.96kWh (8 modules) from SUG NEW ENERGY + compatible 8 kW high-voltage hybrid inverter
Result:
- Charges from solar during the day
- Discharges from 4–9 PM during peak rates
- Provides 24+ hours of backup for essential loads
- Estimated annual savings: 2,400–2,400–3,000
- Payback period: ~5 years (including federal tax credit)
