Monitoring, Protection & SCADA
4 Product Series · 4 Models available
A solar or storage plant that cannot be observed and controlled loses money to silent faults. QDTB monitoring and SCADA products span data gateways, data collectors, protection relays and full supervisory control systems, gathering real-time generation, voltage, current and alarm data from inverters, meters and batteries. Multi-protocol support — Modbus, MQTT, IEC 61850 and more — unifies equipment from different vendors into one platform, while protection relays add the fault detection and tripping needed for grid-code compliance. Remote operation and maintenance, alarm management and reporting keep asset managers in control of fleets spread across multiple sites and time zones.

Available Series
Gateway
→Gateway Series — Multi-Protocol Data Gateways
Communication gateways concentrate inverter, meter and sensor data onto a single protocol, bridging RS485, Ethernet, 4G and WiFi to the monitoring cloud.
Data-collector
→Data-Collector Series — High-Density Data Loggers
Data collectors log high-frequency generation, voltage and current data from large arrays, buffering locally and forwarding to SCADA or the cloud.
Protection-relay
→Protection-Relay Series — Grid-Code Protection
Protection relays implement the under/over-voltage, under/over-frequency and islanding protection required for safe grid connection.
SCADA
→SCADA Series — Supervisory Control Systems
Full supervisory control and data acquisition systems that coordinate PV, storage and loads, with operator interfaces, trending and remote dispatch.
Application Scenarios
Plant Monitoring
Gateways and collectors stream performance data from every inverter and meter to one platform.
Remote O&M
Cloud dashboards and alarm push enable fault diagnosis and firmware updates without site visits.
Grid-Code Compliance
Protection relays implement under/over-voltage and frequency tripping required by utilities.
Energy Management
SCADA coordinates PV, storage and loads to optimise self-consumption and demand charges.
Multi-Site Fleets
Centralised supervision of distributed rooftops and plants from a single control room.
Substation Integration
IEC 61850 and Modbus interfaces tie plants into utility SCADA and dispatch systems.
Technical Advantages
Multi-Protocol Support
Modbus, MQTT, IEC 61850 and REST unify equipment from different manufacturers.
Real-Time Alarm Management
Threshold alarms, event logging and push notifications shorten fault response time.
Protection Relay Functions
Voltage, frequency and islanding protection for grid-code and safety compliance.
Remote Control & Firmware
Remote parameter setting and firmware updates reduce truck rolls and downtime.
Frequently Asked Questions
What is the difference between a gateway and a SCADA system?
A gateway concentrates device data onto one protocol; SCADA adds supervisory control, alarms, trending and operator interfaces on top.
Which protocols do you support?
Modbus TCP/RTU, MQTT, IEC 61850, and standard REST/cloud interfaces, covering most inverter and meter vendors.
Can I monitor multiple sites from one place?
Yes, our cloud platform aggregates fleets of distributed plants into a single dashboard with per-site drill-down.
Why do I need a protection relay?
Utilities require under/over-voltage, under/over-frequency and islanding protection; a certified relay is mandatory for grid connection in most markets.
Can the system send alarms to my phone?
Yes, alarm push via app, email and SMS keeps operators informed in real time.
