Description

• Great capabilities in a small casing

  1. ED-1020 photovoltaic meter

  The ED-1020 meter is probably the world’s smallest photovoltaic system meter with such a substantial number of measurement functions. The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing. All buttons and the graphic display are backlit, which greatly facilitates operation in shaded places, e.g. when taking measurements under ground-mounted PV systems. Large memory significantly shortens preparation of documents after the measurement.

  2. ED-IRM-1 solar radiation and temperature meter

  Small, but indispensable for testing PV systems. By measuring solar radiation values, as well as panel and ambient temperatures, it provides the necessary data to convert the results into STC conditions. A built-in recorder with a memory of 5000 records enables the instrument to be used as a tool in the PV plant design process, as well as to diagnose panel shading problems.

  ED-1020 | Measured parameters

  • The open circuit voltage of the PV panel or a chain of panels, up to 1000V DC.
  • RMS voltage of the AC network up to 600 V with frequency measurement.
  • Short circuit current of a PV panel or chain of panels – up to 20 A DC.
  • Insulation resistance of PV panels – measuring voltage of 250, 500 or 1000 V, simultaneous measurement of two values: R_ISO+ and R_ISO-.
  • Insulation resistance of AC circuits – measuring voltage 250, 500 or 1000 V.
  • Resistance of protective conductors and equipotential bonding with ± 200 mA current. Low-current resistance measurement, audible and visual signalling.
  • Measurement of PV panels operating current and AC current – all with external clamp.
  • AC/DC power Measurement.
  • Diode test with 200 mA current, automatic polarity detection. Test of blocking diodes with 1000V DC voltage.

  ED-1020 | Tightness and durability

  The meter performs well in harsh environmental conditions. Protection against the ingress of dust and water is provided by the housing rated at IP65. This is especially important for measurements on photovoltaic systems, which are outdoor installations.

  ED-1020 | Communication and software

  Measurement data from the ED-1020 can be transferred to a computer via Bluetooth wireless communication. Saving the downloaded data to popular formats and printing ensured by S_Reader. In order to generate a report on electric shock protection use the optional software: S_Reports PLUS.

  ED-1020 | Trouble reSYNC!

  It may happen that in the course of measurements the master meter moves away from the IRM-1 so far, that communication between them is lost. If the measurements are continued, then after the connection is restored, the results will be automatically supplemented with environmental parameters, which in the meantime were recorded by the IRM-1 in its temporary memory, and converted into STC conditions.

  ED-IRM-1 | Measured parameters

  • Solar radiation intensity (irradiance) in W/m² or BTU/ft² h.
  • PV panel temperature in °C or °F.
  • Ambient temperature in °C or °F.
  • Inclination angle of panels
  • Orientation of the panels with the built-in compass.

  ED-IRM-1 | Communication and software

  Measurement data from the ED-IRM-1 can be transferred to a computer via the USB port. In addition, the device has a built-in wireless LoRa interface (Long Range) for automatic data exchange with the master meter – even over long distances.
