Operating Voltage Window
An operating voltage window is the DC voltage range within which an inverter or optimizer can function properly.
Product(s)
EI Inverter (EU)
A battery storage ready hybrid inverter available in single phase and three phase options.
GO Inverter
A battery storage ready hybrid inverter that can be AC or DC coupled for new or retrofit solar installations
What does Operating Voltage Window mean?
An operating voltage window is the DC voltage range within which an inverter or optimizer can function properly.
Why check the operating voltage window?
Designers need strings to stay within voltage limits across hot and cold conditions. Too low and the inverter may not operate; too high and the system may exceed equipment limits or code requirements.
How it relates to Tigo
Tigo system design uses module voltage, string length, and equipment voltage windows to verify compatibility.
