In a PBI World
Successful PBI -PV-Systems are High Yield
Robust and Reliable

How we achieve improved Inverter yields?

• MPP tracking
• Some Systems chase the MPP
• In essence these Inverters are always next to
  the MPP
• Some Inverters calculate the MPP
• Higher yields can be achieved by constantly be in
  on the MPP
• Tracking Sequence Speed

8
How we achieve improved Inverter yields?

• BiSi Anti Islanding
• Bidirectional Safety interface
• Grid Monitoring process with minimal Grid Impact
• Multiple inverters in one system no longer
  interfere with each other

9
How we achieve improved Inverter yields?

• Low start up voltage
• High Efficiencies at low power

Higher System Yields

• What are further contributing factors?
• Less System Downtime
• Less inverter failures

Reliable Inverters

• Over-dimensioning of components
• Components can loose their electric qualities
  over time
• Capacitors
• Switches
• To ensure 15 year lifetimes use more or larger
  components than necessary
