Combiner Box With 3 In & 3 Out

WARNING!! INSTALLER TO READ BEFORE INSTALLATION.

WHEN CONNECTING SOLAR PANELS ON INSTALLATIONS YOU NEED TO CONSIDER THE VOLTAGE AND CURRENT SAFETY FACTORS.

EG. 12 PANELS CONNECTED IN SERIES. STRING 1 – 6 PANELS, STRING 2 – 6 PANELS
STRING 1 - 6 (PANELS) X 41.2VDC (VOC) X 1.15 = 284.28 VDC
STRING 1 - 1 (PANEL) X 13.96A (ISC) X 1.25 = 17.45 A
STRING 2 - 6 (PANELS) X 41.2VDC (VOC) X 1.15 = 284.28 VDC
STRING 2 - 1 (PANEL) X 13.96A (ISC) X 1.25 = 17.45 A
STRING 1 + 2 = VOLTAGE = 284.28 VDC
STRING 1 + 2 = AMPS – 17.45 A +17.45 A = 34.90 A

IN THIS EXAMPLE A 32A ROTARY ISOLATOR WILL THEREFORE NOT BE SUITABLE FOR THIS INSTALLATION, RATHER USE A SUITABLY RATED DC MCB.
