This solar panel tester measures the maximum power point (MPPT) and open circuit voltage of solar panels up to 800W. It draws its power directly from the panel under test, so no external power supply is needed, making it a practical tool for on-site commissioning checks and panel performance verification.

Key features for solar panels 800W testing

• Auto MPPT detection, automatically adjusts the measurement interval based on the panel's power output.
• Manual MPPT detection, press the test button for a single-point maximum power scan.
• Open circuit voltage, displayed in real time on the LCD.
• Self-powered, runs from the solar panel being tested, no external power supply required.
• Protection, over-voltage, over-temperature, over-current, reverse connection and overrated power protection.

How it works

In auto MPPT mode the refresh interval changes with the panel's current output: every 5 seconds at 100W, every 15 seconds at 350W, and every 30 seconds at 700W. This keeps readings relevant without needing manual adjustment as conditions change. In manual mode, a single button press triggers one scan and the last result is held on screen for recording.

Applications

• On-site commissioning and performance checks for solar panels
• Verifying panel output before and after installation
• Fault-finding and panel matching across string arrays, including ground mounted solar panels and bifacial solar panels
• Checking individual panels within a set of 10 solar panels for degradation or damage

Installation and safety notes

Disconnect the panel from all connected equipment and loads before testing. Do not exceed the tester's rated voltage of 60V or current of 35A. Use only within the rated power range of 5 to 800W. Intended for qualified solar installers and electricians familiar with DC PV systems.
