PV-ISOTEST

Product catalog summary

Introduction
The document introduces the PV-ISOTEST, an instrument designed for the verification, maintenance, and safety of photovoltaic systems up to 1500VDC. It highlights the shift in photovoltaic technology towards higher rated voltages, allowing for longer strings and reduced energy loss, thus improving profitability.

Specifications
The PV-ISOTEST is compliant with the IEC/EN62446 standard and is capable of performing safety checks on photovoltaic systems with voltages up to 1500VDC. It features dual insulation modes, a ground fault locator (GFL) function, and can verify insulation resistance, continuity of protective conductors, and display DC and RMS voltages.

Functions and Features

Insulation Resistance: Provides immediate results (OK | NO) for insulation resistance of active conductors without needing an external switch.
Fault Localization: Identifies and localizes faults due to low insulation, such as water or humidity infiltration.
Continuity Verification: Checks the continuity of protective conductors with a test current greater than 200mA.
Parameter Evaluation: Evaluates Dielectric Absorption Ratio (DAR) and Polarization Index (PI) for assessing insulation quality.

Technical Specifications

Voltage Range: 3 ÷ 1500 V with accuracy of ± (1.0% reading + 2 digits).
Resistance Range: 0.00 ÷ 1999 Ω with varying resolutions and accuracies.
Test Voltage: 250, 500, 1000, 1500 V for insulation resistance measurements.
Power Supply: Operates on 6x1.5V alkaline or 6x1.2V rechargeable batteries, with approximately 500 tests per battery set.

Standards and Safety
The instrument adheres to multiple safety and measurement standards, including IEC/EN61010 and IEC/EN61557, ensuring reliable and safe operation in various environmental conditions.

Accessories
The PV-ISOTEST comes with a set of banana cables, MC4 adapters, a carrying case, straps, software, and connectors. Optional accessories are also available for enhanced functionality.

Conclusion
The PV-ISOTEST by HT Italia is a comprehensive tool for professionals in the photovoltaic sector, offering advanced features for system verification and fault detection, ensuring compliance with industry standards and enhancing system reliability.

Identification and localization of the fault Photovoltaic technology is changing. The design and production of installations increasingly takes into consideration the increase in rated voltage, which allows for the realization of strings up to 30% longer, for a higher generated power and, at the same time, uses a smaller number of components, which allows for the reduction of energy loss (BoS) up to 30%, while improving profitability. In this way, an increasing number of photovoltaic installations are realized with a rated voltage close to 1500VDC, with a view to obtaining the maximization of...

INSULATION IN DUAL MODE VERIFIES GFL (Ground Fault Locator) function LOCALIZES Verification with an immediate result (OK | NO) of the insulation resistance of the active conductors of a module, string or entire photovoltaic field, according to the requirements of standard IEC/EN62446, with no need for an external switch to short-circuit the positive and negative terminals. PV-ISOTEST provides the precise position of a possible single fault of low insulation found on a string of the PV system due, for example, to water or humidity infiltrations. IDENTIFIES Automatic identification, with one single...
