Why Most C&I Energy Storage Projects Fail Before Commissioning
1. Failure Happens Early — Not Late
Contrary to popular belief, most failed C&I projects fail:
-
At system design
-
At integration planning
-
Before first power-up
2. The Hidden Integration Gap
Common failure points include:
-
PCS mismatch with load characteristics
-
Insufficient DC bus stability
-
Control logic copied from residential systems
These issues are not visible on marketing slides — but they dominate real projects.
3. The Role of Power Electronics
Battery quality matters, but power electronics define whether the system survives commissioning.
Engineering-focused storage solutions place PCS behavior, thermal margins, and fault handling at the center of system design.

4. Engineering Conclusion
C&I storage does not fail because technology is immature — it fails because engineering assumptions are wrong.
