The sale covers three versions in Enphase's own store: the 40-amp model with a NEMA 14-50 plug and J1772 connector for $799.20 instead of $999, and the hardwired 48-amp model with a J1772 or NACS connector for $899.20 instead of $1,124. The 64- and 80-amp versions are not discounted.
According to Enphase, the 40-amp version charges at up to 9.6 kW, has a 25-foot cable and a pre-wired NEMA 14-50 plug, a sealed NEMA 4 enclosure, Wi-Fi, Bluetooth and Ethernet, OCPP 2.0.1 and a built-in revenue-grade meter. Enphase lists UL and Energy Star compliance. Its load management is meant to adjust charging to the home's power use; whether that avoids a panel upgrade in your house is for your electrician to decide.
The store shows a 4.3-star rating labeled "Ratings from Amazon". That is a customer rating, not an independent test. The charger is on the qualifying list of the Los Angeles utility LADWP, which pays rebates on home chargers.
There is no federal credit to stack any more; the IRS ended the home charger credit for equipment placed in service after June 30, 2026. What is still available is listed in “EV tax credit ended: state rebates and charger incentives you can still get in late 2026”.
