Device Overview

OpenEVSE Advanced Series 48A Level 2 - SAE J1772 is a high-power home EV charging station built around OpenEVSE's open-source hardware and software ecosystem. It is most useful for buyers who want a 48 A Level 2 charger with local control, open integration options, and fewer closed-cloud assumptions than many consumer chargers.

The official assembled SAE J1772 version is rated for 208-264 V AC Level 2 charging at up to 11.5 kW / 48 A. Charge current can be adjusted from 6 A to 48 A in 1 A increments, which matters when matching the charger to a branch circuit, panel capacity, or a temporary charging limit.

Charging And Connector Fit

This record is scoped to the SAE J1772 assembled station. The official store page lists a 25 ft 48 A J1772 cable, NEMA 14-XX input-cable compatibility, and circuit-dependent charging limits: 24 A on NEMA 14-30, 40 A on NEMA 14-50, and 48 A on NEMA 14-60.

Those details are important for comparison because the same 48 A headline can mean different practical charging speeds depending on the plug, breaker, installation method, and local electrical code.

Smart Control And Integration

OpenEVSE documents Wi-Fi setup, MQTT, open APIs, and OCPP 1.6J. That makes this charger a stronger fit for Home Assistant, local automation, and custom energy workflows than a charger that only exposes a vendor app.

The OpenEVSE homepage also lists real-time solar diversion as a smart feature. Treat that as an integration-capable feature rather than a guaranteed one-button solar mode: the final behavior depends on the external monitoring data, firmware configuration, and automation setup used at the site.

Installation Notes

This is an EV charger, not an energy meter, solar inverter, battery, or gateway/data-logger page. It should be installed and circuit-sized by qualified electrical personnel, especially because 48 A continuous charging normally implies a suitably rated circuit and hardware path.

Strengths And Limits

Strengths include high charging power, adjustable current, open protocols, MQTT/OCPP support, kWh/amp metering, and official images and purchase data from the OpenEVSE store.

Limitations include the official store's sold-out state during this review, the assembled J1772 model's not-available-for-export-to-Canada caveat, and the need for technical comfort when using the open integration features deeply.
