Photovoltaic power stations work in outdoor conditions with high DC voltage, complex power distribution and strict lightning protection standards, requiring comprehensive testing during construction acceptance, daily operation and regular safety audits. Guilin Huayi Peakmeter Technology develops a full set of dedicated measuring instruments for all PV scenarios, serving distributed rooftop solar and large ground-mounted power plants globally.
Our complete PV testing products cover high-voltage multimeters, AC/DC clamp meters, harmonic power analyzers, insulation testers, earth resistance testers and non-contact voltage detectors. The PM8250 1700V multimeter tests solar panel open-circuit voltage with harmonic filtering and temperature measurement. PM2128 and PM2108 clamp meters measure AC/DC current up to 1000A, supporting inrush current capture and live wire warning. The high-precision PM8237 True-RMS multimeter features dual display and USB data export for long-term voltage recording.
MS2205 power clamp meter analyzes three-phase power and up to 20-order harmonics with data storage and PC connectivity. MS5203 and MS5215 insulation testers check modules, transformers and high-voltage cabinets, automatically calculating PI and DAR values with auto discharge protection. MS2302, MS2306/2307/2308 earth resistance testers verify PV bracket grounding and lightning protection via multi-pole measurement and anti-interference technology, while PM8909C safely detects live AC voltage without direct contact.
PEAKMETER instruments meet EN61010 and CE standards, with rugged dustproof, moisture-proof shells and practical functions including data logging, overload protection and backlight. We offer OEM customization and a 1-year global warranty. Our all-in-one testing solutions help solar operators identify insulation aging, grounding defects and harmonic faults in advance, lowering maintenance costs and ensuring safe, stable and efficient power generation of photovoltaic facilities.
PEAKMETER delivers a complete lineup of dedicated insulation testers engineered exclusively for PV system insulation verification, including MS5203 and MS5215 models to match low-to ultra-high voltage testing demands across all solar equipment.
MS5203 is optimized for routine insulation checks on PV panels and combiner boxes, supporting up to 1000V test voltage, automatic calculation of Polarization Index (PI) and Dielectric Absorption Ratio (DAR), built-in capacitive load auto-discharge and multi-group data storage for comparative analysis. For booster station transformers and high-voltage power distribution equipment, MS5215 offers five selectable output voltages up to 5000V with a maximum measuring range of 5TΩ, meeting strict grid inspection specifications.
PEAKMETER insulation testers comply with IEC and CE international safety standards, equipped with data hold, backlight display and overload protection to adapt harsh outdoor working conditions. Whether for new PV project acceptance, regular safety audits or post-fault re-inspection, our reliable insulation testing instruments accurately detect insulation degradation, hidden leakage and wiring defects. They help solar operators eliminate electrical risks in advance, extend equipment service life and ensure continuous, compliant safe operation of photovoltaic power stations worldwide.
Solar inverters convert DC power from PV arrays into usable AC power, making accurate voltage and current testing essential for efficiency evaluation and fault diagnosis. PEAKMETER delivers specialized multimeters and AC/DC clamp meters dedicated to inverter measurement.
PM8250 1700V multimeter safely measures ultra-high DC open-circuit voltage of PV strings, equipped with LPF filter to eliminate inverter harmonic interference. PM2128 and PM2108 clamp meters support wide-range AC/DC current up to 1000A and 600A respectively, featuring NCV warning, inrush current capture and low-impedance mode for precise readings. The 30000-count PM8237 records long-term voltage data via USB, while MS2205 further analyzes three-phase harmonics and power factors.
PEAKMETER products comply with IEC and CE standards, built with overload protection for harsh outdoor sites. They help technicians identify abnormal current, voltage imbalance and power loss, ensuring stable, efficient operation of solar inverters.
PEAKMETER delivers all-in-one professional testing kits for full-lifecycle PV station inspection, complying with IEC 62446 safety standards. Our high-voltage multimeters, DC clamp meters and insulation testers accurately measure string voltage, leakage resistance and grounding performance to eliminate electric shock and fire hazards on 1000V/1500V DC arrays.
Equipped with CAT III/IV safety ratings and anti-overload protection, portable tools detect module hotspots, faulty diodes and loose wiring joints efficiently. Supporting data logging and True RMS measurement, they simplify routine maintenance, commissioning acceptance and power generation efficiency diagnosis.
Lightweight, dustproof instruments suit harsh outdoor plant environments. Matching thermometers and test accessories complete systematic safety verification, helping O&M teams cut downtime and maximize long-term power output of solar facilities.
