Adds two ports to one existing 60 A feeder. Cuts panel-board space consumption by half compared to two single-port units.
Duplex, triplex, and small multifamily where two households share one feeder. Dynamic 48 A split balances simultaneous sessions.
Plumbers, HVAC techs, and landscape fleets with 2 vans returning to base overnight. Simultaneous slow charge is the efficient profile.

Two single-port units on separate feeders typically run $3,500–$5,200 for the same 2-stall result. The Duo's economics come from the shared infrastructure, not the hardware itself.
Section 30C treats each port as a separate "item" with a $100,000 cap on the commercial credit, so a dual-port Duo doubles your cap exposure. Residential installs in eligible census tracts get up to 30% / $1,000 per household.

Single-port sibling, $399. Pair two Classics on separate feeders if each port needs full 40A independent power.
