The HT Instruments PVCHECKs-PROPLUS is a commissioning tester kit for PV systems. The kit includes a malfunction commissioning tester (PVCHECKs-PRO), a remote unit for the measurement of irradiance/temperature/inclination of PV modules (SOLAR03), a reference cell for the irradiance measurements (HT305), and a PT1000 probe for cell temperature measurements (PT305).

The HT Instruments PVCHECKs-PRO is a commissioning tester designed to take all safety measurements and verifications of PV installations in accordance with IEC/EN62446. The malfunction commissioning tester is capable of taking the following measurements:

• Insulation measurement on PV modules/strings/fields up to 1500VDC (with PI and DAR calculation)
• Open circuit voltage (VOC) up to 1500V in accordance with IEC/EN62446
• Short circuit current (ISC) up to 40A in accordance with IEC/EN62446
• Continuity of protective conductors with 200mA
• Polarity
• GFL function for fault finding on strings and PV modules
• Tests on single-facial and bi-facial modules
• Automatic acquisition of the cell calibration value (by using suitable cells)

The remote unit HT Instruments SOLAR03 has been designed to measure irradiance [W/m2] and temperature [°C] both on Monofacial and Bifacial photovoltaic modules by means of the relevant probes connected to it, and to take measurement of tilt angle of PV panels. The unit has been designed for use in combination with a Master instrument, to carry out measurements and recordings during maintenance operations on photovoltaic installations. The unit can be connected to the following Master instruments and accessories - PVCHECKs-PRO, HT305, PT305. 

The HT Instruments HT305 is a reference cell for irradiance measurements.

• Irradiance Measurement up to: 1400W/m2
• Basic accuracy: +/- 3.0% reading
• Type of cell: Monocrystalline
• FOV angle: >160 degrees
• IP rating: IP65 according to IEC/EN60529
• Output connector: custom 5-pin HT connector
• Connection cable: approx. 2m

The HT Instruments PT305 is a PT1000 probe for cell temperature measurement. The probe has connection for the SOLAR03 - Remote unit for measurement of irradiance, temperature, and inclination of PV modules.
