MI3116 PV ANALYSER XA TESTER
MI 3116 PV Analyser XA
The MI 3116 PV Analyser XA is a photovoltaic analyzer and electrical installation tester designed for testing PV systems up to 1500 VDC. It integrates insulation measurement, I-V curve testing, Isc/Uoc testing, PE continuity, and polarity checks into a single instrument, with wireless irradiance and cell temperature capture via a Wi-Fi remote unit.
This makes it a particularly useful tool for teams that need to validate performance, detect deviations from STC, and accelerate field inspection, maintenance, or troubleshooting campaigns.
Measures I-V curves on PV systems up to 1500 V / 40 A / 48 kW.
Performs insulation tests on PV strings up to 1500 V.
Carries out Isc and Uoc tests for module and string validation.
Records irradiance and panel temperature with a wireless remote unit.
Calculates STC values and compares them with the manufacturer’s nominal data.
Includes auto-sequences, organized memory, and graphical/numerical review of results.
Ideal for:
O&M and commissioning teams in utility-scale or C&I PV plants up to 1500 V.
Personnel who need to correlate actual field performance vs. STC.
String diagnostics, initial and periodic inspections, and fault resolution.
Not ideal for:
Users who only require a basic verification without I-V curve testing or comparative STC analysis.
Applications requiring confirmed native integration with SCADA/ERP/LIMS without prior validation.
Benefits
Less time per diagnosis — combines PV electrical testing and I-V curve tracing in a single instrument, avoiding equipment changes in the field.
Greater evaluation reliability — captures irradiance and temperature in real time with a Wi-Fi remote unit, reducing context-related measurement errors.
Better validation of actual performance — calculates STC values and compares them against the module’s nominal data.
Greater troubleshooting accuracy — the I-V curve, Isc, and Uoc make it possible to identify deviations that a single spot reading would not show.
More consistent workflows — auto-sequences standardize category 1 tests and simplify inspection campaigns.
Result traceability — touchscreen, measurement storage, and numerical/graphical review directly on the instrument.
Scalability for modern plants — supports up to 1500 VDC, 40 ADC, and 48 kW in I/U curve testing, aligned with more demanding PV installations.
Less data rework — the correction function allows parameters entered incorrectly in previously completed measurements to be adjusted.
Applications
Commissioning of PV plants up to 1500 V — problem: validating that strings and modules deliver the expected performance from the first inspection; how it solves it: combines insulation, polarity, continuity, Isc/Uoc, and I-V curve testing with remote irradiance/temperature measurement; result: faster technical acceptance with traceable results.
Periodic maintenance and degradation verification — problem: production loss without a clear cause or deviation from specification; how it solves it: calculates STC values and compares them with the panel’s nominal values, helping detect underperformance, soiling, aging, or string issues; result: better prioritization of corrective actions and less diagnostic time.
Troubleshooting of strings and high-efficiency or bifacial modules — problem: the fault cannot be identified with an isolated voltage or current measurement; how it solves it: supports bifacial panels and enables review of the I-V curve, Isc/Uoc, and actual irradiance/temperature conditions; result: more reliable diagnosis for specialized maintenance.
Report generation for operations, quality, or technical audits — problem: scattered data and low test standardization; how it solves it: MESM allows uploading/downloading data, analyzing I/U curves, and issuing professional reports; result: consistent documentation for customers, EPCs, insurers, or technical management.
