SPM-800 SOLAR MPPT POWER METER INSTRUCTION MANUAL Preface Thank you for purchasing this solar power meter. To use this product safely and correctly, it is recommended to read this User Manual thoroughly, especially the "Safety Information" section. Overview SPM-800 Solar MPPT Meter can measure the maximum power of a solar panel quickly. It measures maximum power (Pmax) of a solar panel, open-circuit voltage (Voc), and shortcircuit current (Isc) simultaneously while displaying these measurements on screen. MPPT is the most important indicator for judging if a solar panel generates enough power in low efficiency settings and is commonly used for measuring solar panel power or troubleshooting faulty modules. Key Features 1. No battery required. Powers on automatically when connected to a solar panel. 2. Manual/Auto modes 3. Overheating, overvoltage, and overcurrent protection 4. Protection against reverse connections 5. Overload protection Carefully read the contents of the "Safety" and "Warning" sections included in this User Manual. Warning: Read the "Safety Information" carefully before use. Accessories Relevant safety information and warnings are included in this User Manual. Read the related contents thoroughly and follow all warnings and precautions. Contact your supplier if any accessory listed below is missing or damaged. 1. User Manual 1 pc 2. MC4 cables (UT-L101) 1 pair 3. Solar panel spanners 1 set Safety Information This meter is designed with double insulation with a maximum working voltage of 60 VDC. The protection supplied by the Meter may be compromised or lost without following the following operating instructions. 1. Check the Meter and test leads before use to avoid any damage to the meter or cause any problems. 2. Stop using the Meter if the test lead is exposed, the housing is damaged, there is an abnormal display, or if other problems occur during use. 3. Do not use the meter without the housing sealed. Otherwise, it may present a risk of electric shock. 4. If the test leads are damaged, replace it with the one with the same model or specification. 5. Do not touch the exposed wire, connector, unused input terminal or circuit during measurement. 6. Use caution when working with voltage over 30 VDC. Hold the test lead behind the guard to prevent electric shock. 7. Do not exert voltage over the specified value of the panel between terminals or between any terminal and earth ground. 8. Only use test leads (MC4 cables) with the same voltage and current ratings that are included with this meter. 9. Do not keep or use the Meter in environments with high temperature, high humidity, strong electromagnetic fields, or with flammable and explosive substances. 10. Do not alter the internal wiring without authorization to avoid damaging the Meter or causing safety hazards. 11. Measure a known intrinsic voltage or current before use to ensure the Meter works as expected. 2 Electrical Symbols Symbol Description Danger! High voltage!

Voltage of maximum power point: This is the maximum voltage while the solar panel is generating power. Current of maximum power point: This is the maximum current while the solar panel is generating power. Open-circuit voltage: The voltage without load Short-circuit current: The current of shorted positive and negative poles of the solar panel Test is completed Automatic test Manual test Countdown for the test to be completed Functional Buttons Button Description HOLD: Data hold AUTO: Automatic test MANUAL: Manual test SPM-800 Instruction Manual 1) 1. In automatic sampling mode "AUTO": When the current data is held, the Meter keeps counting down until 0.0s is reached, but sampling is not triggered. Sampling will proceed for 1s of countdown when HOLD is disabled. 2) 1. Test starts 3s after the AUTO button is pressed. The Meter adjusts the test interval automatically based on the value of the current power and refreshes the display (refreshes once at intervals of 5s for 100W; and 15s for >100W). 2. To stop automatic testing, power on the Meter, then press the AUTO/MANUAL button when the first countdown of 15s is up. "Test Completed" will flash on the screen three times if the button is triggered within the set waiting time. The triggering of the AUTO/MANUAL button is enabled when pressed after the countdown is up. 3) 1. Test starts 3s after the MANUAL button is pressed. The Meter starts scanning the maximum power point once and refreshes the display. 2. To avoid damage to the Meter caused by triggering the MANUAL button frequently, a sampling interval for protecting the Meter is built-in (the triggering of the MANUAL button is enabled when pressed at intervals of 5s for 100W; and 15s for >100W). "Test Completed" will flash on the screen three times if the AUTO/MANUAL button is triggered within the set waiting time. The triggering of the AUTO/MANUAL button is enabled when pressed after the countdown is up (the countdown is not displayed on the LCD). Note: The triggering of the MANUAL button is disabled at the critical time "0.0s", as the Meter has entered into sampling state. 5 Operating Instructions The symbols " " near the input terminals indicate that the voltage under test shall not be over the specified value. 1. Connect the red test lead to the red (+) terminal, and connect the black test lead to the black (-) terminal. Then, connect the MC4 cable to the corresponding ports at both ends of the solar panel (connect to the load in parallel). 2. The value of Voc is displayed in real time when the Meter is powered on. 3. When the AUTO button is pressed for automatic testing, the Meter adjusts the test interval automatically based on the current displayed power. 4. Press the MANUAL button for manual testing. Test results can be obtained each time the MANUAL button is pressed. Warning: 1. Disconnect from the power grid for solar panel testing. The Meter does not test in the measurement category "CAT II or above". 2. The Meter is used for solar panel tests only. 3. Do not measure voltage over 60 VDC or power over 800W, otherwise it may damage the Meter and cause personal injury. 4. If the symbol appears on the display, stop using until the Meter cools down. 6 Specifications SPM-800 Instruction Manual Accuracy: ±(a% of reading + b digits); guaranteed for 1 year Ambient temperature: 0°C~40°C(32°F~104°F); relative temperature: 75% Function Range Resolution Accuracy Input protection ±(a% of reading + b digits) Remark Measuring open-circuit voltage (V) 12~60V 0.1V Measuring power (W) 5~800W 0.1W Short-circuit 0~35A 0.1A current (A) ±(1.5%+5) 5~10W ±(1.0%+5) 11W~500W ±(1.0%+10) 501W~800W ±(1.5%+5) ±(1.5%+5) 100Vrms If 100V is present, entering measurement mode will be limited and the symbol "OVERLOAD!" will appear on the LCD. 1)The Meter is powered by the solar panel and does not require a battery. The input voltage to the Meter should be 12V. 2)DC voltage measurement serves as a power measurement, but the input amplitude should be between 12V and 60V. 3)The specified accuracy is calculated using a standard light source as the input. Warning: · The temperature should be between 18°C~28°C. The fluctuation range of ambient temperature stabilizes within ±1°C. When the temperature is less than 18°C or greater than 28°C, the error of temperature coefficient added will be "0.1 x (specified accuracy)/°C". · The Meter powers off automatically within 10 minutes of inactivity. In the auto-off state, the Meter can be restarted by pressing any button. Maintenance Warning: Do not open the back of the housing to avoid damage to the Meter or personal injury. General maintenance · Clean the casing with wet cloth and mild detergent. Do not use abrasives or solvents. · If there is any problem with the Meter, stop using it immediately. · Calibration and maintenance must be performed by qualified professionals. 7Adobe PDF Library 17.0 Adobe InDesign 20.0 (Macintosh)
