Description

What is the HT PVCHECKs ProPlus suitable for?

The PVCHECKs-PRO is designed for electrical safety tests and commissioning tasks on PV systems up to 1500 V DC. Typical use cases include initial verification, periodic testing, maintenance, troubleshooting and documentation of tests according to IEC/EN 62446-1.

In everyday O&M, the instrument is especially relevant for teams that need to test many strings efficiently: open-circuit voltage, short-circuit current, insulation resistance, protective conductor continuity and polarity can be covered in a compact workflow. The GFL function also supports narrowing down insulation faults within a string.

Reliable implementation requires more than operating the device. Before use, measurement tasks, SOLAR03 accessories, module and string structure, internal data storage, report logic and team responsibilities should be defined.

Measurement functions

Which tests does the PVCHECKs ProPlus cover?

The measurement functions of the HT PVCHECKs ProPlus are mainly relevant for commissioning and maintenance workflows: basic electrical tests, insulation measurement, continuity, Voc/Isc, GFL function and integration of irradiance and temperature data.

SOLAR03 · HT305 · PT305

Integrating environmental parameters correctly into the PV workflow

For evaluating PV measurements, the electrical measured value alone is often not enough. Irradiance, module temperature and ambient temperature must be recorded traceably and assigned to the correct measurement time.

SOLAR03 remote unit

SOLAR03 is the remote unit for irradiance, temperature and tilt. The connection to PVCHECKs-PRO is made via Bluetooth BLE.

HT305 reference cell

HT305 is used for irradiance measurement and stores calibration parameters internally. In the ProPlus workflow, it is important to assign the right cell correctly to the respective measurement setup.

PT305 temperature probe

PT305 is used for cell or module temperature measurement. Without correct temperature assignment, STC values and comparability lose significance.
