Di-LOG Advanced Solar PV Test Kit

The Di‑LOG SL550 Solar PV Test Kit is a complete, high-performance solution engineered for the installation, commissioning and maintenance of modern solar photovoltaic systems. Combining a precision solar irradiance survey meter, a CAT III 1500V DC True RMS Bluetooth clamp meter and professional MC4 test leads, the SL550 provides everything required for accurate solar PV testing in a single, portable kit.

Designed for both domestic and commercial PV applications, the SL550 enables comprehensive system verification by measuring solar irradiance, module temperature, DC voltage, AC/DC current, power and energy. The advanced survey functionality supports IEC 62446-1 compliant testing, the international standard for grid-connected PV system documentation, commissioning and inspection. This includes measurement of irradiance from 50 to 1400W/m², panel surface and underside temperature, roof pitch and array orientation, ensuring accurate system performance validation and correct installation alignment.

SL104 Key Features:

• Solar Irradiance Measurement to 1400W/m2: Indicating in real time how much solar power is available to convert into electricity.
• Inbuilt Cell Temperature Sensor: The inbuilt surface probe located on the base of the SL104 offers a quick indication of the surface cell
  temperature.
• External Cell Temperature Probe: The attachable external probe connects directly to the SL104 and offers a quick indication of the underside cell temperature of the panel.
• Inbuilt Magnetometer Compass: The inbuilt compass enables you to determine the roof direction to gain an accurate array direction.
• Roof Pitch Inclinometer: The integrated inclinometer will assist in determining an accurate pitch of the roof angle the array is intended to be mounted on helping calculate the efficiency of the array.
