Description

What is the MI 3116 PV Analyser XA suitable for?

The MI 3116 PV Analyser XA is designed for testing large 1500 V PV plants, initial verification, periodic testing, maintenance, troubleshooting and report generation. It supports tests according to EN 62446 as well as measurements according to IEC 61829 and STC corrections according to IEC 60891.

Key measurement functions include insulation resistance on PV strings, UOC/ISC measurement, I/U curve measurement, 200 mA continuity testing, polarity testing and the acquisition of irradiance and PV module temperature via the remote unit.

For practical use in solar park O&M, the measurement range is not the only relevant factor. What matters is whether O&M teams use the PV module database, Auto Sequences, memory structure, remote environmental measurement and report creation in a consistent way.

Measurement functions

PV measurements for 1500 V systems

The MI 3116 PV Analyser XA is designed for PV measurements with high voltages and currents. For O&M teams, it is important to define which measurements become a repeatable standard process.

UOC / ISC

Measurement of open-circuit voltage and short-circuit current on PV strings. The voltage measuring range extends up to 1699 V DC, while the intended use is for PV systems up to 1500 V DC.

I/U curve

I/U curve measurement up to 1500 V, 40 A and 48 kW. The curve can be evaluated numerically and graphically and supports PV string diagnostics and assessment.

Insulation resistance

RISO PV measurements with test voltages up to 1500 V DC. Results can be used for Roc+, Roc- and Roc and form part of PV safety testing.

200 mA continuity

R-low measurement with at least 200 mA measuring current for testing protective conductor and equipotential bonding connections.

Environmental parameters

Irradiance and PV module temperature are captured through the remote unit and accessories such as reference cell and temperature probe. These data are essential for STC calculation and assessment.

Auto Sequences

Auto Sequences can guide test procedures and standardize measurements. Teams should define in advance which sequences are mandatory for which plant and measurement tasks.

O&M use

From measuring instrument to robust measurement process

The MI 3116 PV Analyser XA offers extensive technical functionality. To turn that functionality into usable results in daily O&M work, measurement process, data structure and reporting must be prepared cleanly.

Measurement strategy

Which strings, sub-arrays or plant sections are measured, when and with which scope of testing?

PV module database

PV module data influences STC values, target-value comparison and evaluation. Incorrect or incomplete module data can make interpretation more difficult.

Remote measurement

The A 1785 PV Remote WL captures environmental parameters. Positioning, synchronization and assignment to the measurement should be clearly regulated in the process.

Reporting

I/U measuring instrument, STC values, measurement status, workspaces and export data must be organized so that reports remain traceable and comparable.

Data & communication

Interfaces for measurement data, remote unit and PC workflow

The MI 3116 PV Analyser XA combines local storage, PC communication and wireless communication with the remote unit. Teams should define the mandatory data path before the rollout.

USB & RS232

The operating manual describes USB and RS232 communication with the PC. These interfaces are relevant for data transfer, the software workflow and technical integration.

Wi-Fi Remote WL

Wi-Fi is used for communication between the main instrument and the A 1785 PV Remote WL. This allows irradiance and cell temperature to be captured and assigned during the measurement.

Bluetooth

The instrument includes Bluetooth v4.2 BR/EDR and BLE. The team process should define whether and how Bluetooth is used in the specific setup.

microSD & storage

The main unit has a microSD card slot. microSD cards up to 512 GB are supported. The storage and export process should be defined within the O&M team.
