Di-LOG's Solar Solution - The SL350 and NEW SL550 Solar PV Kits!
Solar PV Testing for the Next Generation of High Voltage Systems
The rapid evolution of solar photovoltaic technology is bringing both greater efficiency and new challenges for installers and electrical contractors. As module efficiency improves, the voltage characteristics of PV strings are increasing, with open circuit voltage (VOC) regularly exceeding the traditional 600V range that many standard clamp meters were originally designed to measure.
For today’s installer, this shift is not just a technical detail, it directly impacts safe working practices, correct equipment selection, and ultimately compliance. This is where purpose-built Solar PV test kits such as the Di-LOG SL350 and the newly launched SL550 are becoming essential tools on site.
At Di-LOG, we continue to be a trusted name in test and measurement equipment, and expanding our solar testing range with the new SL350 Professional Plus and SL550 Advanced PV Kit was necessary. Designed for solar installers and maintenance professionals, these comprehensive test kits provide the essential tools needed to install, commission, and maintain solar PV systems with confidence, accuracy, and efficiency.

SL350 Professional Plus: The Perfect Balance of Power and Precision
The SL350 kit‘s clamp meter is the powerful DL6414 TRMS 1000A AC/DC Clamp Meter. This meter offers a wide range of measurement capabilities, including Voltage Measurement up to 1000V AC/DC, making it ideal for high VOC measurements on large domestic and medium commercial PV systems. With advanced features like Inrush Current, Low Impedance (LoZ), Variable Frequency Drive (VFD), and an inbuilt LED Flashlight, the DL6414 is the ultimate tool for demanding applications.
For the included irradiance meter, the SL104 also incorporates a compass inclinometer, allowing you to quickly assess roof pitch angles and array directions on-site. This valuable tool helps your customers to plan and execute installations with precision.
The SL350 Professional Plus is a comprehensive toolkit that combines essential measurement capabilities with advanced features. At its core is the SL104 Solar Irradiance Survey Tool, a versatile device that measures both solar irradiance and temperature. With its built-in internal and external probes, you can accurately measure PV panel surface and cell temperatures, ensuring optimal system performance aligning with the industry standards defined in IEC 62446-1.

SL550 Advanced Kit: The Latest in Solar PV Testing
The SL550 Advanced Kit is the ultimate tool for solar professionals seeking the highest level of performance and precision. With this CAT III 1500V DC True RMS Bluetooth clamp meter, the SL550 provides everything required for accurate solar PV testing in a single, portable kit. Like the SL350, it features the versatile SL104 Solar Irradiance Survey Tool for comprehensive solar irradiance and temperature measurements.
The SL550 takes it a step further with the inclusion of theDL6415 CAT III TRMS 1500A AC/DC Clamp Meter. This high-performance meter like the DL6415BT offers 1500V DC voltage measurement, 60,000-count backlit display, Inrush Current measurement, Power Measurement (kW/kVA/kVAr/), Energy Measurement (kWh/kVAh/kVArh/), Power Factor, Harmonics and a digital bar-graph. These advanced features will empower Electricians to troubleshoot complex issues and optimise system performance.
