What to include

These five items let us quote accurately in the first reply. If any is still open, tell us what you know — we can help you work it out.

  • Stack rated power and output voltage window
  • Required DC bus voltage for your inverter or load
  • Cooling method — natural, air or liquid
  • Application and duty cycle
  • Quantity and target delivery date

Not sure of the specification? Send us what you have — stack voltage range, system power, and what it is for. Selecting the right converter is our job, not yours.
