Solar Panel Multimeter MPPT Auto Manual Tester Open Circuit

The Solar Panel Multimeter MPPT Auto Manual Tester Open Circuit is a high-precision, solar-powered tool designed to optimize and verify your photovoltaic setup. With a clear-definition LCD display and backlight, this meter makes it easy to measure maximum power point (MPP) power, voltage, and current across a range of PV configurations. It runs directly from a solar panel (not included), eliminating the need for batteries and delivering an economical, energy-efficient solution for manufacturers, installers, and enthusiasts alike.

Benefits & Tips

• Auto MPPT for fast, automatic measurements: Press Auto MPPT to let the meter test itself and automatically adjust the interval based on current power value, refreshing the display as needed.
• Manual MPPT for precise control: Use Manual MPPT to tailor the test interval to your project; the meter adjusts intervals according to power, providing accurate, step-by-step readings.
• Versatile for multiple users: Ideal for PV panel manufacturers, operators, installers, and hobbyists who need reliable open-circuit voltage, MPPT voltage, and MPPT current readings in one compact device.
