Di-Log SL350 Professional Plus Solar PV Test Kit
The Di-Log SL350 Professional Plus Solar PV Test Kit helps engineers install and maintain solar PV systems with confidence. It brings together solar irradiance, temperature, current, voltage, direction and pitch checks in one practical kit. As a result, users can complete key site checks with fewer separate tools.
This kit suits domestic and commercial solar thermal and solar PV installation work. It measures DC voltage, including open circuit voltage up to 1000 V DC, so it supports high VOC checks on larger arrays. It also helps confirm available solar power before and during panel testing.
Solar Survey Measurements
The SL104 solar irradiance survey tool measures irradiance up to 1400 W/m². It also checks panel surface temperature with its built in internal probe. In addition, the external probe connects to the tool for underside cell temperature checks.
On-site surveys are easier because the SL104 includes a compass and inclinometer. The compass helps confirm proposed array direction from 0° to 360°. Meanwhile, the inclinometer measures roof pitch from -90° to 90° to support array planning.
Electrical Testing Capability
The DL6414 clamp meter adds AC and DC electrical test functions to the Di-Log SL350 Professional Plus Solar PV Test Kit. It measures current up to 1000 A and voltage up to 1000 V AC/DC. This makes it useful for demanding solar PV work where safe, wide range testing is needed.
Extra functions include LoZ, inrush current, variable frequency drive testing and an integrated LED torch. The compact body and 35 mm jaw opening help with access in tight spaces. With CAT IV 600 V and CAT III 1000 V safety ratings, the kit supports protected field use across its stated ranges.
