Multi-channel PV Module IV+MPPT Steady-State Test System

Product Description

The Multi-channel PV Module IV+MPPT Steady-State Test System is a high-precision testing platform developed by Lecheng Intelligent for advanced photovoltaic research and reliability evaluation. The system is specifically designed for perovskite, tandem, and thin-film photovoltaic devices, supporting comprehensive testing from small-area devices to standard mini-modules.

By integrating a Class AAA LED steady-state solar simulator, multi-channel source-meter units, independent temperature control modules, and intelligent automation software, the system enables simultaneous IV characterization, MPPT tracking, and long-term stability monitoring under controlled illumination and environmental conditions.

Unlike traditional single-channel test setups, this platform supports up to 19 independently controlled channels, allowing parallel testing of multiple samples in a single experiment. This significantly increases data throughput and shortens R&D validation cycles, making it ideal for perovskite material screening, process optimization, and lifetime assessment.

Product Functions

1. Multi-Channel IV Testing with Independent Control

The system supports forward and reverse IV scanning, 9-point fitting methods, and customizable scan intervals. Each channel operates independently, enabling flexible parameter configuration for different devices within the same test run.

Electrical Testing Capabilities

Real-time IV and PV curves are displayed and recorded for all channels simultaneously, with instant alarms triggered upon abnormal conditions.

2. Advanced MPPT Tracking Algorithms

To address the hysteresis and transient behavior commonly observed in perovskite solar cells, the system integrates multiple MPPT algorithms.

Supported MPPT Algorithms

These algorithms ensure accurate maximum power point tracking under steady-state illumination and during long-term aging experiments.

3. Independent Temperature Control & Environmental Simulation

Each test channel is equipped with an independent temperature control module, enabling precise thermal regulation and monitoring.

Temperature Control Specifications

This allows accurate evaluation of PV module performance and degradation under high-temperature, low-temperature, and combined light-thermal stress conditions.

4. Intelligent Software & Automated Data Management

The system is powered by an in-house developed intelligent software platform that supports fully automated testing workflows.

Software Capabilities

This software architecture ensures high data integrity and traceability during long-term stability studies.
