Realising a Compact, High-precision Power Testing System
Compact PV Inverter Testing For PV Inverter Production Lines
The HIOKI M7103 is a power measurement module that boasts power analyser class accuracy. This product delivers exceptional scalability, high-speed data recording and unparalleled stability in multi-channel power efficiency measurement. It is the optimal choice for embedded applications, offering valuable solutions for all your data recording needs.
Realise 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 maximise 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 Synchronisation 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.
HIOKI M7103 Applications:
- Power evaluation for every channel of high-voltage PV inverters
- Shipping inspection and quality evaluation of high-voltage PV inverters
- BMS (Battery Management System) evaluation and charge/discharge testing of ESSs
- Performance evaluation of large-capacity battery packs for electric vehicles and PHVs (Plug-in Hybrid Vehicle)
