…while simplifying deployment and maximizing long-term returns for commercial and industrial users.

PowerKeeper Introduces Sungrow’s “007” Reliability Philosophy

One of the biggest highlights of the launch is that PowerKeeper became:

🏆 The first modular C&I energy storage system to successfully pass seven extreme challenge tests

This forms Sungrow’s:

👉 “007” reliability value proposition

…focused on redefining safety, resilience, and operational stability for modern commercial battery storage systems.

Seven Extreme Tests: Reliability Built for 20+ Years

Commercial energy storage systems must operate reliably for decades under demanding real-world conditions.

To validate this, Sungrow subjected PowerKeeper to:

⚡ More than 700 pre-delivery tests

The seven extreme tests focused on three critical dimensions:

1. Environmental Resilience

Stable Operation in Harsh Conditions

✔ Flood Resistance

• Operates normally after:
  👉 24-hour immersion in 50 cm of water

✔ Wide Temperature Stability

• Full-power operation from:
  👉 –20°C to 40°C

…without derating.

This is critical for:

• Industrial sites
• Outdoor ESS deployments
• Harsh climate regions
• Utility-scale PV+ESS projects

2. Structural Integrity

No Fire or Explosion After Physical Impact

✔ Pendulum Impact Test

PowerKeeper withstands:

👉 250 kg pendulum impact

…with:

• Minor surface damage only
• No structural failure
• No abnormal thermal behavior

✔ Drop Resistance

The system survived repeated drops from:

👉 1.6 m to 5 m heights

…while maintaining:

✔ Structural integrity
✔ Thermal stability

3. Intrinsic Safety

No Fire Spread, No Explosion Splash

Integrated Fire Protection Includes:

🔥 Aerosol fire suppression system
🔥 Self-extinguishing flame design
🔥 Active venting protection

These features help prevent:

• Fire propagation
• Explosion debris projection
• Personnel hazards
• Equipment damage

…especially important for:

• PV + ESS installations
• Commercial rooftop systems
• Industrial energy storage sites
