Z300 HE – 1500V / 40A
Z300 HE 1500V / 40A Photovoltaic tester. Measure Isc, Voc, Riso, Rs polarity, fault location and tone tracer technology. Comes with one-click connection and save to cloud functionality. Cloud platform comes as free, Premium or Teams packages.
Description
The Z300 PVT HE is a portable, cloud-connected PV string analyzer for utility-scale 1500 VDC solar farms built on high-efficiency modules (TOPCon, HJT, IBC, n-PERT). A proprietary measurement method delivers safe, accurate Isc readings up to 40 A on high-capacitance modules where conventional testers struggle.
One instrument covers the IEC 62446-1 string-level commissioning tests (Voc with polarity check, Isc, Riso) plus ground fault localization to ± 0.5 PV module, series resistance Rs, string capacitance C, a continuous voltmeter, and an integrated tone generator with handheld pickup. The emazys MPP method estimates Vmpp, Impp, Pmpp and fill factor, with optional STC correction via the Tempirra environmental sensor.
Bluetooth-controlled from iOS and Android. All measurements, GPS coordinates, photos and environmental data sync to the emazys cloud (Free, Premium, Team) for commissioning, maintenance and compliance reporting in PDF, CSV and Excel.

Notes
MPP estimation. The MPP characteristics (Vmpp, Impp, Pmpp, FF) are estimated and anchored by precision Voc, steady-state Isc, measured Rs and string capacitance C. Values are estimated, not directly measured, and are intended for string-level performance verification, comparison against module datasheet values and identification of underperforming or mismatched strings.
Voltage abort threshold. The Z300 PVT HE is rated for 1500 VDC operation. The hardware includes a safety margin and aborts the Isc measurement if Voc exceeds an internal abort threshold of approximately 1600 V. Operation above 1500 VDC is not supported.
Ground fault localization accuracy. The ± 0.5 PV module localization precision assumes low string series resistance and stable measurement conditions. On strings with elevated series resistance (long cable runs, partial soiling, weak connections), the reported fault position may shift, but remains useful as a starting point for inspection.
Specifications are subject to change without notice. All values are typical unless otherwise specified. For the most current data sheet, contact emazys.
