DC:AC Ratio
DC:AC ratio compares the total rated DC power of the solar array to the rated AC output capacity of the inverter.
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 DC:AC Ratio mean?
DC:AC ratio compares the total rated DC power of the solar array to the rated AC output capacity of the inverter.
What is a good DC:AC ratio?
There is no universal perfect ratio. Designers use DC:AC ratio to balance equipment cost, expected production, clipping, climate, orientation, utility limits, and storage behavior. The math is simple; the design implications enjoy making themselves complicated.
How it relates to Tigo
Tigo’s Microinverter Tax content discusses why equal DC:AC ratios can behave differently depending on whether clipping occurs at the module level or array level.
