What’s Inside the White Paper?

Every CPMS vendor claims OCPP compliance. Few can tell you what happens when connectivity drops, hardware misbehaves, or a firmware update silently breaks your billing. This guide reveals what actually happens in the field.

The Compliance Myth: Why "OCPP-certified" hardware still fails to talk to "OCPP-compliant" software

The Dialect Dilemma: Why two "compliant" chargers can speak OCPP, and still not understand each other

The Version Trap: Why upgrading to OCPP 2.0.1 can push your entire network to the lowest common denominator

Battle Scars: Real-world case studies on ghost sessions, blown fuses, and the firmware brick

Why It Matters

Why This White Paper Matters

Most OCPP failures don't announce themselves. Your dashboard shows 100% network health while stranded drivers are calling support. Ghost sessions leak revenue silently. A timestamp format change silently drops every meter value your chargers send.
Ocean's guide helps CPOs shift from "Is our platform OCPP-compliant?" to "Can our platform handle what actually happens in the field?"
