Our verdict
The Ultimate 48A is the value pick for a new hardwired circuit: full 48 A charging, Wi-Fi app control and OCPP in Grizzl-E’s aluminum UL Type 4 case. It must be wired directly to a dedicated circuit (the manual forbids a plug, extension cord or adapter), with 48 A on a 60 A circuit and 40, 32, 24 or 16 A on 50, 40, 30 or 20 A circuits, set by an internal DIP switch. Wiring is for a licensed electrician, and the built-in ground-fault protection means no extra GFCI is needed downstream.
The Grizzl-E Connect app handles a charging timer, schedules and current limits, and OCPP lets it join third-party networks. The radio is 2.4 GHz only, and the manual explains splitting a mesh network so the charger can connect. The case is rated from -22°F to 122°F, so very cold sites should look at a -40°F model.
This is the 2026 New Ultimate 48A, with a 3-year warranty or five years as an option. It is on the ENERGY STAR list, and Grizzl-E says it is certified for Canada. In Canada we track only Grizzl-E’s own store, which listed this J1772 version as out of stock when we checked in November 2026.

Grizzl-E Ultimate 48A questions
What breaker does the Grizzl-E Ultimate 48A need?
A dedicated 60 A circuit for the full 48 A. The manual pairs 48 A with 60 A, 40 A with 50 A, 32 A with 40 A, 24 A with 30 A and 16 A with 20 A, each on a double-pole breaker of the circuit rating. The current is set with a DIP switch inside the front cover, with the power off, and the wiring is for a licensed electrician.
Can the Grizzl-E Ultimate 48A plug into a NEMA 14-50 outlet?
No. The manual says the New Ultimate 48A must be hardwired to the panel and must not be used with a plug, extension cord or adapter; a hardwire kit comes in the box. If you want to plug into an existing outlet, Grizzl-E sells plug-in models such as the Classic and the Classic Connect 40A.
Does the Grizzl-E Ultimate work with 5 GHz Wi-Fi?
No. It connects only to a 2.4 GHz network, with a signal of -67 dBm or better and a password of up to 38 characters. Mesh networks that mix 2.4 and 5 GHz can fail; Grizzl-E’s manual suggests splitting out a separately named 2.4 GHz band, setting up a 2.4 GHz guest network or adding a 2.4 GHz extender.
