What Is OCPP?

OCPP stands for Open Charge Point Protocol. It's an open-source communication standard that allows EV chargers to talk to charging management systems — regardless of who made the charger or who made the software.

Think of it like USB-C for chargers. Before OCPP, every charger brand used its own proprietary protocol. You couldn't mix a Wallbox charger with a ChargePoint management system. With OCPP, any OCPP-compatible charger works with any OCPP-compatible platform.

The Two Versions You'll See

Version Released Key Features
OCPP 1.6 2015 Basic charging control, transaction management, metering
OCPP 2.0.1 2020 Enhanced security (TLS), device management, ISO 15118 support, smart charging, better monitoring
GIZNT chargers support both OCPP 1.6 and OCPP 2.0, giving you maximum compatibility.

Why OCPP Matters for Home Users

1. You're Not Locked In

Without OCPP, your charger only works with the manufacturer's app and platform. If the company:

  • Goes out of business → your smart charger becomes dumb
  • Shuts down their servers → you lose remote access, scheduling, and monitoring
  • Changes their pricing → you pay more or lose features
  • Releases a buggy update → you're stuck with it

With OCPP, you can switch management platforms anytime. Your charger keeps working no matter what happens to the manufacturer.

2. Solar Integration

Want to charge your EV from your solar panels? You need a charger that can communicate with your solar management system.

OCPP makes this possible. Platforms like SolarEdge, Fronius, and others can integrate with any OCPP charger to:

  • Start charging when solar production exceeds household demand
  • Pause charging when clouds roll in
  • Optimize for maximum self-consumption

Without OCPP, you're limited to the manufacturer's solar integration — if they even have one.

3. Future-Proofing

EV charging technology is evolving fast. New features being developed on OCPP platforms include:

  • Vehicle-to-Grid (V2G) — sell energy back to the grid from your EV
  • Dynamic tariff optimization — automatically charge when rates are lowest, even if they change hourly
  • Smart grid integration — utilities can request you reduce charging during peak demand (for a credit)
  • Multi-charger coordination — if you get a second EV, your chargers can balance the load automatically

If your charger supports OCPP, you get access to these features as platforms add them — no new hardware needed.

Why OCPP Matters for Businesses

If you're installing chargers at a business, OCPP isn't optional — it's essential.

Multi-Charger Management

Manage 1, 10, or 100 chargers from a single dashboard regardless of brand. Mix GIZNT with other OCPP chargers and control them all from one platform.

Billing & Access Control

OCPP platforms handle:
  • Per-session billing (charge users by kWh or time)
  • RFID card management
  • User accounts and payment processing
  • Usage reporting and analytics

    • Regulatory Compliance

    Many jurisdictions now require OCPP compliance for commercial EV charging installations. Even if yours doesn't yet, it likely will soon.

    Popular OCPP Management Platforms

    Platform Best For Pricing
    ChargeFox Australia/NZ Per-station
    EO Charging UK/Europe Enterprise
    EV Connect US commercial Per-station
    SteVe Open-source / DIY Free
    OCPP-Cloud Multi-brand management Freemium
    Wallbox EcoSmart Small businesses Per-charger

    OCPP vs Proprietary: The Real Cost

    Let's compare the total cost of ownership over 5 years:

    Proprietary Charger (No OCPP)

  • Purchase: $450
  • Monthly platform fee: $5-10/month × 60 months = $300-600
  • If company shuts down: Replace charger ($450+)
  • Solar integration: Limited or none
  • 5-year total: $750-1,050+ (possibly $1,500+ if company fails)

    • OCPP Charger (GIZNT)

  • Purchase: $658 (7kW) to $998 (22kW)
  • Monthly platform fee: FREE (use open-source) or $3-8/month
  • If company shuts down: Switch platforms, $0
  • Solar integration: Yes, via OCPP platform
  • 5-year total: $658-998 + optional platform fees

    • The OCPP charger costs less over time, even with a higher upfront price, because you're never forced to replace it or pay escalating platform fees.

    How to Check If a Charger Supports OCPP

    Before buying any EV charger, check for OCPP support:

    1. Read the spec sheet — Look for "OCPP 1.6" or "OCPP 2.0" or "Open Charge Point Protocol" 2. Ask the manufacturer — "Can I connect this charger to a third-party OCPP management platform?" 3. Beware of vague language — "Smart connectivity" or "WiFi enabled" ≠ OCPP. Some brands claim "smart" features but use proprietary protocols.

    Chargers That Support OCPP (as of 2026)

    Brand Models OCPP Version
    GIZNT All wall-mounted models 1.6 + 2.0
    Wallbox Pulsar Plus, Commander 2 1.6J
    EO Charging EO Mini Pro 1.6
    Enel X JuiceBox Pro 1.6
    ABB Terra AC 1.6 + 2.0

    Chargers That Do NOT Support OCPP

    Brand Models Note
    Tesla Wall Connector Proprietary Tesla protocol
    ChargePoint Home Flex Proprietary (commercial models do support OCPP)
    Grizzl-E Classic No OCPP (Astonic upgrade available)
    Emporia Level 2 Proprietary app only

    Setting Up OCPP on Your GIZNT Charger

    GIZNT chargers come OCPP-ready out of the box. Here's how to connect:

    Step 1: Choose an OCPP Platform

    For home users, we recommend starting with a free option like SteVe (open-source) or the GIZNT app (included). For businesses, choose a platform based on your needs (see table above).

    Step 2: Configure the Connection

    In the GIZNT app: 1. Go to Settings → OCPP Configuration 2. Enter your platform's WebSocket URL (e.g., `ws://your-server:9000`) 3. Enter your charger identity (serial number, auto-filled) 4. Tap Connect

    Step 3: Verify Connection

    Your charger will appear in the OCPP platform dashboard within seconds. You can now:
  • Start/stop charging sessions remotely
  • Monitor real-time power consumption
  • Configure RFID cards
  • Set charging schedules
  • View usage history

    • Common Questions About OCPP

    Does OCPP work over WiFi?

    Yes. OCPP communicates over WebSocket connections, which work over WiFi, Ethernet, or cellular. GIZNT chargers use WiFi.

    Can I use OCPP and the manufacturer's app at the same time?

    Usually no — most chargers connect to one OCPP endpoint at a time. When you connect to a third-party platform, you'll manage the charger through that platform instead of the manufacturer's app.

    Is OCPP secure?

    OCPP 2.0.1 includes mandatory TLS encryption and certificate-based authentication. OCPP 1.6 supports TLS but doesn't require it. For maximum security, use OCPP 2.0.1 with a platform that enforces TLS.

    Does OCPP cost money?

    The protocol itself is free and open-source. Management platforms may charge fees, but free options exist (SteVe, OCPP-Cloud free tier). The GIZNT app provides basic OCPP management at no additional cost.

    Can I switch OCPP platforms later?

    Yes — that's the whole point. Disconnect from one platform and connect to another. Your charger hardware doesn't change.

    The Bottom Line

    If you're buying a smart EV charger in 2026, OCPP support should be a non-negotiable requirement. Here's why:

    1. Freedom — Switch platforms anytime, never locked in 2. Savings — Free platforms available, no forced subscriptions 3. Solar ready — Integrate with any solar management system 4. Future-proof — New features via software, not hardware 5. Business-ready — Required for most commercial installations

    GIZNT chargers include OCPP 1.6 and 2.0 support on every wall-mounted model, along with WiFi, RFID, and IP65 weather protection — all included, no add-ons required.
