Top Reasons US Installers and Property Managers Choose the ZB04

1. OCPP 1.6 Protocol – Built for Commercial Networks.

If you are managing multiple chargers across a property, OCPP 1.6 is essential. It allows you to integrate the ZB04 with any OCPP-compliant backend for billing, usage tracking, and remote diagnostics. This makes it ideal for apartment complexes, office buildings, hotels, and fleet depots.

2. Load Balancing Saves Thousands in Electrical Upgrades.
Installing multiple chargers usually means upgrading your electrical service. Not with the ZB04. Its built-in load balancing system dynamically distributes power among all connected chargers, keeping the total draw within your existing panel capacity. This can save thousands of dollars in infrastructure costs.

3. 4.3-Inch Display – Clarity at a Glance.
Large, bright, and readable in direct sunlight. It shows charging status, energy delivered, fault alerts, and real-time voltage/current. No app required for basic operation.

4. Multiple Authentication Methods.
Supports RFID card, APP, QR code, and plug-and-charge. Perfect for mixed-use properties where residents, employees, and visitors all need access. The ZB04 can be configured to require authentication or allow open charging.

5. ETL Listed to UL 2251 & UL 2594.
Tested by a Nationally Recognized Testing Laboratory. Accepted by US electrical inspectors, utility rebate programs, and insurance providers. No gray-market uncertainty.

6. 22kW Three-Phase Capability.
For commercial locations with three-phase power, the ZB04 delivers up to 22kW — significantly faster than standard single-phase 7kW chargers. This is ideal for fleet vehicles that need rapid turnaround.

7. Durable and Weatherproof.
IP65-rated for the wall unit and IP54-rated for the plugged connection. It operates from –30°C to +50°C, making it suitable for indoor garages and outdoor parking lots across all US climates.

8. Versatile Connectivity.
Supports RFID, WiFi, Bluetooth, 4G, and Ethernet. You can deploy the ZB04 in a basement garage with Ethernet or a remote lot with 4G — whatever your infrastructure allows.
