DAQ-IOT PV O&M Platform - Inverter & Weather Station Realtime Monitoring, Data Acquisition & Alerts

DAQ-IoT PV Operation & Maintenance Management Platform — Real-Time Online Monitoring, Data Acquisition, Statistics and Alarms for Inverters, Weather Stations and Control Devices

System Introduction

The DAQ-IoT PV Operation & Maintenance Management Platform is a comprehensive management platform integrating data acquisition, data statistics, intelligent alarms and O&M management. It helps PV power plants improve power-generation efficiency and helps O&M companies improve efficiency and management, reduce O&M costs and ultimately increase economic benefits. Through smart gateways it acquires operating data and status from on-site inverters, weather stations, integrated control devices and other equipment, achieving real-time online monitoring and diagnosis of the PV plant.

Application Scenarios

• Monitoring and O&M management of commercial and industrial distributed PV plants
• Monitoring and O&M of centralized PV stations
• Household PV and similar scenarios

Function Overview

Main Functions

1. Device online monitoring — real-time monitoring of inverters, combiner boxes, grid-connection devices and weather stations, enabling remote monitoring and remote meter reading; when a hidden risk or fault is detected, O&M personnel are notified promptly by SMS or phone call.

2. Online and offline O&M — full O&M workflow management based on cloud and mobile, with automatic data and task flow, making O&M standardized and efficient while greatly improving efficiency and reducing cost.

3. Power-generation reports — built-in power-generation data analysis reports in multiple dimensions, with custom reports also supported to meet different station requirements.

4. Energy-flow diagram — shows the physical layout of equipment at each level of a PV site and the power-generation and loss information of each device node.

5. Inverter health assessment — comprehensive health analysis of inverters from equivalent utilization hours, power factor, conversion efficiency, string dispersion rate and other aspects.

6. Power-generation analysis — analysis of generation, generation efficiency, equivalent utilization hours and current (power) dispersion rate of a site or inverter, identifying problems in time and improving generation efficiency.

7. PV data dashboard — multi-site PV comprehensive data dashboards and single-site dashboards, which can also be customized according to specific requirements.
