The Z200 PV Analyzer is controlled over WiFi using a web browser. The user interface is a website containing 6 modes each designed for different uses.
  • Ground Fault Locator (Riso < 3 MΩ)
  • Disconnect Locater
  • Impedance spectrum, Voc, Isc, Rs and Riso (1000V, 15 A)
  • State Machine AI output to support the user in the field
  • Module test: Voc, bypass diode check, and Rp test (PID detection)
  • Tone generator and amplifier probe for mapping PV arrays
  • Timer mode – Ground Fault Locator (monitor intermittent Riso issues)
  • Save data as PDF, CSV or JSON

Ground Fault
– Open circuit voltage
– Low frequency norm
– Low freq norm with load
– Isolation Resistance (RISO)
– Estimated position of RISO

Disconnect
– Entered cable capacitance
– Length of cable to positive terminal
– Length of cable to negative terminal
– Capacitance measured from the positive terminal
– Capacitance measured from the negative terminal
– Low frequency norm (+ terminal)
– Low frequency norm (− terminal)
– Position of disconnect

Timer
You can set a timer to perform the ground fault test and thus leave the instrument during testing. This can be an advantage if the ground fault is periodic.
– Open circuit voltage
– Low frequency norm
– Low freq norm with load
– Isolation Resistance (RISO)
– Estimated position of RISO

Tone Generator
Mode 1 sends out a medium frequency tone between positive and negative terminals. Mode 2 alternates between high and low frequency between ground and positive, and between ground and negative.
