all-in-one diagnostic tool made for solar professionals
CEM DT-1500PV , a multifunction PV tester with I‑V curve tracing is a single, all-in-one diagnostic tool made for solar professionals. It is designed to help with installing, commissioning, maintaining, and troubleshooting photovoltaic (PV) systems.
This tool combines basic safety and function checks with advanced performance analysis. It confirms that a photovoltaic (PV) system has been installed safely and is producing the expected amount of power.
This single device brings together many different electrical testing functions. It also lets you measure and analyze the current-voltage (I‑V) characteristics of individual solar panels and strings of panels.
This tester works with PV systems that have up to 1500 volts DC and up to 30 amps. It is commonly used during both the initial setup and ongoing maintenance of solar systems.
Safety:
IEC61010-1 CAT IV 600V
IEC 61010-2-034 CAT III 1000V AC, CAT III 1500V DC
CE, UL, CSA, and TÜV listed for maximum safety and global compliance
Applications:
-- Residential rooftop solar installations.
-- Commercial and industrial PV systems.
-- Utility-scale solar farms.
-- Solar power plant commissioning.
-- Preventive maintenance and periodic inspections
I-V curve tracing
An I‑V curve is a chart that shows how much current and voltage a solar panel produces under certain light and
temperature conditions. The I-V curve is like a health check for a solar panel.
PV systems up to 1500 V DC and 30 A
Installing a 1500V solar system is primarily used in large-scale commercial and utility projects.
But it comes with stricter safety and engineering demands, DT-1500PV will be best tool for solar professionals
---- Main functions : ----
I-V Curve Tracing for PV modules and strings
it evaluates the entire PV performance. Detect mismatch, demaged cells
Maximum Power (Pmax) Measurement on DC and AC side to check efficiency
Determines the maximum power output of the PV module under existing weather conditions. Manufacturers rate
solar panels by maximum power.
PV module/PV string , Open Circuit Voltage (Voc) Testing
Measures the maximum voltage when no load is connected.
PV module/PV string, Short Circuit Current (Isc) Testing
Measures the maximum current when the module terminals are shorted
Insulation resistance
The tester applies a high DC voltage (typically 500V, 1000V, or 1500V) between the PV conductors
and the protective earth (ground) to measure resistance
Continuity and Protective Earth Testing
The tester sends a small current through the grounding (earth) wires to measure the resistance of the
connection from the PV array frame all the way back to the main grounding point.
PV String Polarity Verification
A simple but critical check to confirm that the positive and negative DC cables from the PV array are connected
to the correct terminals of the inverter/combiner box.
AC / DC Voltage and Current Measurement
measure real-time AC / DC voltage (V) and current (A) on the live circuit
Solar Irradiance Measurement & Module Temperature Measurement
with Solar Irradiance meter (connectivity by wireless Bluetooth ) that you place on the same plane (tilt and
orientation) as the PV modules to measure the sun's power in W/m².
Attach it to the back of the PV module to measure its operating temperature (°C).
Surge protection device (SPD)
verify that a system's surge protection device is functioning correctly
Auto Test
switch the device to "AUTO" mode.
automating a sequence of mandatory safety and performance tests to save time and reduce errors
