Photovoltaic Installation Tester BENNING PV 1-1+

• testing in compliance with DIN EN 62446 (VDE 0126-23)
• easy – operation by means of keys
• quick – testing within seconds
• safe – safe measurement connection, even if the photovoltaic system is delivering energy

Before commissioning and for periodic inspections, a photovoltaic system must be tested and documented with regard to its perfectly safe technical condition in compliance with DIN EN 62446 (VDE 0126-23). Moreover, electrical measurements are also useful after cleaning and maintenance work in order to continue to ensure an optimum and low-loss functioning of the PV system.

The test includes continuity testing of earth connections, measurement of the open-circuit voltage and short-circuit current as well as insulating resistance measurement between active conductors (+/-) and earth. The BENNING PV 1-1+ is provided with contact-protected PV measuring leads for direct connection to all PV modules/ strings by means of standardized PV connectors. The automatic testing procedure gives a warning in case of wrong DC polarity and automatically performs all necessary steps for a safe measurement.

The BENNING PV 1-1+ allows to carry out the entire test safely, reliably, easily and quickly. The BENNING PV 1-1+ is recommended for daily use by service, cleaning and maintenance teams as well as for solar panel installers and authorized experts for photovoltaics.

Distinct symbols - easy operation

Four steps towards easy and safe PV testing:

1. disconnect the PV module from the inverter
2. connect the PV module to the BENNING PV 1-1+ by means of standardized connectors
3. press the „AUTO“ key and follow the measurements on the LC display
4. press the „STORE“ key to store the entire display indication

BENNING SOLAR Datalogger (download software)

Scope of delivery

• transport/ storage case
• measuring leads with probe tip (L = 1.2 m, red/black)
• crocodile clips (red/black)
• PV measuring leads for MC4 connector (red/black)
• PV measuring leads for Sunclix connector (red/black)
• USB cable
• 6 x 1.5 batteries type AA (IEC LR6)

• Insolation and temperature measuring instrument BENNING SUN 2 (050420) The BENNING PV 1-1+ i+s able to receive the measured values (insolation, PV module / ambient temperature) of the insolation and temperature measuring instrument BENNING SUN 2 via radio connection. For this purpose, the BENNING PV 1-1+ has to be coupled with the BENNING SUN 2 once.
• temperature sensor with suction cup for BENNING SUN 2 for attachment to the rear of the PV module (050424)
• PV module holder for BENNING SUN 2 for safe attachment to the PV module (050425)
• AC/DC current clamp adapter BENNING CC 3 (044038) For being connected to the BENNING PV 1-1+. The measured AC/DC current values can be stored in the memory of the BENNING PV 1-1+ and can be recalled.
• Alternatively, the current of each individual PV string can be made by means of a current clamp with direct current (DC) measurement: We recommend the digital current clamps BENNING CM 10-PV (current measurement up to 600 A AC/DC, item no. 044683), BENNING CM 5-1 (current measurement up to 600 A AC/DC, item no. 044066) or BENNING CM 2-1 (current measurement up to 400 A AC/DC, item no. 044689).
• BENNING TA 5 40 m measuring lead, winder and strap, for the measurement of protective and bonding conductors, connection via 4 mm safety socket/ plug (044039)
