ELEJOY EY800W Solar Panel Multimeter

ELEJOY EY800W Solar Panel Multimeter Photovoltaic Panel Tester | MPPT PV Tester for Sri Lanka

Smart 800W MPPT Solar Panel Multimeter for Fast, Accurate PV Testing in Sri Lanka

The ELEJOY EY800W Solar Panel Multimeter is a dedicated photovoltaic (PV) panel tester designed to measure the real maximum power point (MPPT) output, open-circuit voltage (Voc), current, and power of solar panels up to 800W, 60V, and 35A. Purpose-built for solar installers, maintenance technicians, and serious off-grid enthusiasts, this compact MPPT meter gives instant, reliable insight into panel performance without needing an inverter or charge controller.

Unlike generic multimeters, the EY800W solar panel tester uses a smart MPPT algorithm to automatically scan and lock onto the panel's true maximum power point, displaying Pmax, Vmp, and Imp in real time so you can verify whether a panel is delivering its rated output in field conditions. With a high-contrast backlit LCD, multiple safety protections, and direct panel-powered design (no extra batteries required), the ELEJOY EY800W is a must-have tool for commissioning, auditing, and troubleshooting PV systems in Sri Lanka's residential, commercial, and off-grid installations.

Key Features of the ELEJOY EY800W Solar Panel Multimeter

Advanced MPPT Test (Up to 800W)

Performs both Auto MPPT and Manual MPPT tests to find the panel's true Maximum Power Point up to 800W, displaying maximum power (Pmax), voltage at maximum power (Vmp), and current at maximum power (Imp) for accurate performance verification.

Real-Time Open-Circuit Voltage (Voc) Measurement

Measures and displays the open-circuit voltage (Voc) of the solar panel in real time, helping diagnose issues such as cell damage, faulty bypass diodes, and wiring problems without connecting any external load.

Wide Test Range: Up to 60V / 35A

Supports PV panels and small strings up to 60V and 35A, making it ideal for popular 12V, 24V, and 36V panels and portable folding modules commonly used in rooftop and off-grid solar systems.

No External Power Required

Powered directly from the connected solar panel, eliminating the need for internal or external batteries so the meter is always ready for work in the field.

Real-Time Multi-Parameter LCD Display

Large backlit LCD simultaneously shows key parameters such as voltage, current, and power, with clear digits visible in bright outdoor sunlight or dim indoor environments.

Comprehensive Safety Protection

Built-in protections against over-voltage, over-current, over-temperature, over-rated power, and reverse connection help protect both the meter and the solar panel during testing.

Compact, Lightweight & Field Ready

Pocket-sized, lightweight design with MC4 and alligator clip leads included, making it easy to carry on rooftops, solar farms, and remote off-grid sites.

Common Applications of ELEJOY EY800W

Solar Panel Installation & Commissioning

Verify each panel's Pmax, Vmp, Imp, and Voc during installation to ensure they match datasheet ratings and catch underperforming modules before final system handover.

PV System Maintenance & Troubleshooting

Quickly identify degraded or mismatched panels in strings by comparing measured MPPT power and Voc values, helping prevent energy loss and warranty disputes in residential and commercial arrays.

Off-Grid & Portable Solar Testing

Ideal for testing portable folding panels, camper/RV, marine, and telecom backup systems, ensuring panels deliver the expected power to charge batteries and MPPT controllers efficiently.

PV Auditing & Performance Validation

Use as part of a solar panel tester kit to audit system performance against design calculations, validate installer claims, and benchmark panel output under actual site conditions in Sri Lanka.
