Solar Panel MPPT Tester (EL400B) – Smart Photovoltaic Multimeter with VOC & Power Testing

The EL400B Solar Panel MPPT Tester is a professional photovoltaic multimeter designed for testing solar panels with precision. It measures maximum power point (MPPT), open circuit voltage (VOC), and current performance without requiring an external power source. Built for manufacturers, installers, and solar users, this device ensures accurate testing, improved efficiency, and safe operation in solar applications.

Product Features

Automatic MPPT Testing

Performs real-time automatic detection of the maximum power point, adjusting refresh intervals based on panel output.

Manual MPPT Testing

Enables manual scanning of the solar panel’s maximum power point for detailed performance analysis.

Open Circuit Voltage (VOC) Measurement

Displays the photovoltaic panel’s open-circuit voltage in real time for reliable testing.

Built-In Safety Protections

Equipped with over-voltage, over-current, over-temperature, and over-power protection to ensure safe operation.

Self-Powered Design

Powered directly by the solar panel under test, eliminating the need for external power supplies.
