Compact PV Inverter Testing For PV inverter production lines
Realize high-accuracy measurement without differential probes, even for high voltages
Manufacturers are developing PV inverters that operate at higher voltages to reduce equipment costs and transmission losses. As a result, measurement of PV inverters requires instruments that can accommodate high voltages.
The M7103 supports 1500 V DC CAT II and 1000 V DC CAT III measurement, allowing high voltages to be input directly and measured safely.
In addition, quality is assured during PV inverter testing since accuracy is guaranteed up to 1500 V DC with direct input.
Expandable power meter ideal for PV inverter production lines
The M7103 delivers multi-point power measurement across up to 12 channels in a 4U unit that fits in a 19-inch rack, helping save space and lower costs on PV inverter production lines.
In addition, its expandable design means customers can add or replace modules themselves, providing flexibility when building PV inverter production lines.
Efficiency measurement of multi-MPPT string inverters
Manufacturers are developing multi-string inverters to maximize the generating capacity of solar power systems.
Multi-string inverters are controlled using maximum power point tracking (MPPT) so that they create as much power as possible per string. On production lines, measurements must be made at numerous points to test whether each MPPT is functioning properly.
By using the LR8102's Synchronization Source Sharing function, the M7103 can simultaneously measure power across up to 120 channels. Furthermore, the Synchronization Source Sharing function makes possible stable efficiency measurement.
Unmatched Capability for Capturing Data from High-Voltage Battery Packs
Suitable for Battery Charge/Discharge Testing
Assuring safety when testing cell voltages of a 1500 V battery pack: Achievement unlocked.
Terminal-to-ground voltage: 1500 V DC (CAT II) Insulation
EN IEC 61010 Safety standard-compliant
Since the M7103 has a maximum rated terminal-to-ground voltage of 1500 V, it can accommodate testing of 800 V batteries with an ample margin of safety.
It can also be used to measure cell voltage and temperature of next-generation battery packs that exceed 800 V and power storage systems such as energy storage systems (ESSs) that exceed 1000 V.
Turbocharged data transfers at an interval as short as 5 ms mean you can output data for all cells to an HIL system in real time (when using only the LR8102)
The logger can continuously transfer data at high speed to an upstream system using UDP communication (*1).
Modules sample data at high speed at a rate of up to 5 ms and output it immediately.
Since the data logger continuously acquires live voltage data for measured cells at an interval as short as 5 ms, data can be used in real-time simulation by an HIL system.
In addition, this capability allows comprehensive analysis of charge/discharge characteristics by observing the responsiveness of total voltage as measured by the M7103 Power Measurement Module and individual cells’ voltage data.
- *1:UPD communication functionality is exclusive to the Data Logger LR8102.
