ABB Terra AC W9-P8-RD-MCD-0
ABB Terra AC W9-P8-RD-MCD-0 is a Level 2 home EV charger from ABB with up to 40 A (9.6 kW) output and a J1772 connector — 26 ft cable, networked smart charging.
Our take
Spec-sheet twin territory: this Terra AC variant measures 5.54 W at idle against its RD-CD sibling’s 5.65 W — both land in the top few percent of standby draws among the 56 certified 40 A models here, roughly 49 kWh a year. Everything else matches the family template: 26 ft of cable, longer than 98% of the class, 9.6 kW output that adds about 34 miles of range per hour on a 50 A circuit, Wi-Fi connectivity, and full-speed compatibility with 25 of the 29 EVs we track. Pick between the ABB variants on configuration; the certified numbers barely separate them.
- Best for: Long-reach installs standardizing on ABB hardware across multiple parking spots.
- Trade-off: Idle draw is among the highest in the 40 A class, like its close sibling.
