01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision for your photovoltaic array
A compact instrument designed for the field, this multimeter connects directly to your photovoltaic array to reveal its true performance. It sits in the toolkit of installers and enthusiasts who value exact readings over guesswork.
The EY1800W tests maximum power point and open circuit voltage without needing internal batteries. It suits manufacturers, distributors and homeowners seeking clarity on their solar investment.
02DISPLAY
Readable under direct sunlight
The high definition LCD screen presents data clearly, even when working outdoors in bright conditions. A built-in backlight ensures that figures remain legible against glare, allowing you to interpret results quickly while standing at the panel. The layout separates Pmax, Vmp, Imp and Voc so each metric is distinct and easy to locate.
04FUNCTION
Manual and automatic modes
You can choose how the meter refreshes its data. In manual mode, the test interval adjusts based on the current power value, extending the pause when output is high. Automatic mode handles this adjustment independently, continuously updating the digital display according to live conditions. Both options provide flexibility depending on your workflow.
05SAFETY
Built-in protection mechanisms
The unit incorporates safeguards for over temperature, over voltage, over current, reverse polarity and exceeding rated power. These features protect the instrument during operation, ensuring consistent reliability across different panel types. The range covers voltages from 20 to 120V, accommodating a variety of photovoltaic setups.

About this product
1, Maximum Power Point Testing: This MPPT photovoltaic panel multimeter can accurately test maximum power point and opencircuit voltage, providing essential data for optimizing solar panel performance. 2, Data Display: Pmax indicates the maximum power point power. Vmp indicates maximum power point voltage. Imp indicates maximum power point current. Voc indicates open circuit voltage. 3, Clear Backlight: Equipped with a high definition LCD screen and backlight, this multimeter offers excellent visibility even under direct sunlight, making it easy to read and interpret results. 4, Solar Powered Design: This solar panel multimeter is powered directly by solar panels, without the need for additional batteries, offering an cost effective solution for your measurement needs. 5, Manual Auto Mode: In manual measurement mode, the multimeter automatically adjusts the test interval according to the current power value. The higher the power, the longer the interval, and refreshes the digital display. In automatic measurement mode, the multimeter tests and refreshes the digital display according to the current power value. 6, Multiple Protection Mechanisms: Designed with safety in mind, this multimeter includes over temperature, over voltage, over current, reverse polarity, and exceeding rated power protections to ensure safe operating.
Open Circuit Voltage Detection: LCD screen displays real time voltage of solar panel
If there is no display, it may be due to reverse polarity protection; please check the input polarity.If the device If there is no display, it may be due to reverse polarity protection; please check the input polarity.
If the device displays “Over Power Rating,” it indicates an over power condition; please use the device within the rated power range.
If the device shows “Over Temperature,” it signifies that the over temperature protection is activated; please wait for it to cool down before using it.
If the device displays “Over Voltage,” this is a result of over voltage protection; please use the device within the rated voltage range.
If the device shows “Over Current,” it indicates that over current protection is in effect; please use the device within the rated current range.
