It measures open-circuit voltage in real time and automatically tracks the maximum power point (MPPT) to optimize panel output without drawing energy from your network. This makes it ideal for PV panel manufacturers, distributors, installers, and enthusiasts who want quick, accurate power diagnostics on the go.\u003c\/p\u003e\n\u003cp\u003eChoose between two models to match your needs: EL400B (0.1–400 W, 0–20 A) and EY800W (5–800 W, 0–35 A), both operating from 12–60 V. The device uses solar panels as its power source, offering an energy-saving approach that keeps testing independent of external electricity. Features include Auto MPPT Detection for automatic interval adjustments, Manual MPPT Detection for targeted MPPT scans, a large backlit LCD for clear readings, and built-in protections (over-voltage, over-temperature, over-current, and over-rated power) for safe operation in diverse environments. With a lightweight, portable 165 × 80 × 30 mm form factor and a CE-certified design, it’s ready for field use and shop floor testing alike.\u003c\/p\u003e\n\u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cb\u003eAuto MPPT Detection:\u003c\/b\u003e Press the AUTO MPPT test button and the instrument automatically adjusts test intervals according to current power, refreshing the display (for example, a 100 W panel may refresh every 5 seconds).\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eManual MPPT Detection:\u003c\/b\u003e Use the manual MPPT test button to scan for the maximum power point and instantly refresh the display for precise tuning.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eReal-time Open-Circuit Voltage:\u003c\/b\u003e The open-circuit voltage is shown on the large LCD at any time, helping you monitor panel health during setup and testing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eModel: EL400B \/ EY800W (optional)\u003c\/li\u003e \u003cli\u003eVoltage range: 12–60 V\u003c\/li\u003e \u003cli\u003ePower range: EL400B 0.1–400 W; EY800W 5–800 W\u003c\/li\u003e \u003cli\u003eCurrent range: EL400B 0–20 A; EY800W 0–35 A\u003c\/li\u003e \u003cli\u003ePower supply mode: Solar panel power supply\u003c\/li\u003e \u003cli\u003eDisplay: Large digital LCD with backlight\u003c\/li\u003e \u003cli\u003eDisplay type: Digital display\u003c\/li\u003e \u003cli\u003eOperating temperature: 0–40 °C\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e \u003cli\u003eCertifications: CE\u003c\/li\u003e \u003cli\u003eDimensions: 165 × 80 × 30 mm\u003c\/li\u003e \u003cli\u003eWeight: 470 g\u003c\/li\u003e \u003cli\u003eBattery included: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 × Solar Panel Multimeter\u003c\/li\u003e \u003cli\u003e1 × Connecting Cable\u003c\/li\u003e \u003cli\u003e1 × Alligator Clip Cable\u003c\/li\u003e \u003cli\u003e1 × EVA Toolkit\u003c\/li\u003e \u003cli\u003e1 × User Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarnings\/Reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eOperate within the specified voltage (12–60 V) and power ranges for the selected model (EL400B or EY800W).\u003c\/li\u003e \u003cli\u003eKeep the device away from moisture and extreme temperatures beyond 0–40 °C.\u003c\/li\u003e \u003cli\u003eEnsure correct polarity when connecting cables to avoid incorrect readings or damage.\u003c\/li\u003e \u003cli\u003eThis tester uses a solar panel as its power source; do not connect to external AC power sources.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ci\u003eProviding quality and trusted service since 2002 at intercyprus.com.\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cp\u003ePlease note: All electronic and mechanical equipment, devices and machines sold to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e","brand":"InterCyprus","offers":[{"title":"EL400B","offer_id":51478218604886,"sku":"1005005274566383-EL400B","price":96.9,"currency_code":"EUR","in_stock":false},{"title":"EY800W","offer_id":51478218637654,"sku":"1005005274566383-EY800W","price":107.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S1ec19f0ea4ad48d7967f6c831bf09c78u.webp?v=1759509100","url":"https:\/\/www.intercyprus.com\/products\/400w-800w-solar-panel-power-supply-multimeter-auto-manual-mppt-detection-open-circuit-voltage-tester-troubleshooting-tool-meter","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
