All-in-One PV installation tester for commissioning, troubleshooting, and recording the I-U characteristic curve of PV systems up to 1,500 V / 40 A in a set. Includes data logger SOLAR03, reference cell HT305, temperature sensor PT305, and inclinometer M304. A single press of the "GO" button is sufficient to perform all tests for commissioning according to EN 62446 and to record the I-U characteristic curve. The Seamless mode sequentially tests all strings in a generator junction box with a single button press. I-U characteristic curve analysis of single and bifacial modules and PV strings up to 1,500 V / 40 A. All installation tests (continuity, polarity, Voc, Isc, insulation) on live systems. GFL - Ground Fault Locator to determine the exact position of insulation faults. BMS - Battery Management System to ensure you never run out of battery.
