HOME Products / Services Solar power generation system / environment related products Multi-function high-speed IV measurement system "Lakit" Products / Services Solar power generation system related Multi-function high-speed IV measurement system "Lakit" Mega solar can also be measured efficiently in a short time. The IV tracer with multiple probe holders (patent pending) can measure up to 4 strings simultaneously. * 1 On-site measurement time is significantly reduced to approximately 2 hours * 2 per MW . We are releasing an introduction video of Lakit. Please see the actual inspection. (4 minutes 20 seconds: no voice) We provide a total IV analysis method with a set of IV measuring equipment including a pyranometer, temperature sensor, and data logger, and multifunctional analysis software (IV data analyzer). Based on the amount of solar radiation and temperature accumulated in the data logger, the measured value is automatically converted to the data under the standard test conditions [STC] * 3 by the IV data analyzer . "Rakit" and the "Rakit" logo are registered trademarks of NPC Co., Ltd. (Nos. 5733820 and 5738947). We will quickly deliver an easy-to-understand report on the amount of power generated by the entire power plant and the status of each string. We analyze with our original algorithm and process mega solar data at high speed. Aggregation, analysis, and report output can be done in just 3 minutes * 2 per MW . An abnormal value of the string is detected by three judgment modes. The judgment mode can be selected from three judgment criteria: resistance system, current voltage system, and power system. The open circuit voltage and short circuit current can be determined by comparing the data measured at the same time. Judgment mode Details of outliers Possible factors FF value comparison Increase / decrease of series / parallel resistance Wiring material peeling, cracks, PID phenomenon * 5, etc. Simultaneous measurement value comparison Decrease in open circuit voltage and short circuit current Diode short circuit, disconnection, discoloration of sealing material, etc. Maximum output comparison Maximum output reduction All of the above An example of analysis screen Maximum output histogram after STC conversion (displays total power generation and variation in power generation amount for each string) FF value histogram (string judgment criteria can be set freely, and the tendency of power generation status is displayed) IV curves of all strings requiring inspection and non-defective strings (confirm abnormalities at a glance by comparing) IV curve of string requiring inspection (? IV curve of abnormal string is displayed individually) We have opened a panel maintenance consultation desk. We will answer any questions, such as effective data storage methods, usage methods, and consultations regarding measurement results.
