  1. Sunsynk Noob - Wiring question

    CharlesDavis replied to swazz99jhb's topic in Starting In Solar? Feel free to introduce yourself
    Hi Colin I see a possible change needed to this diagram ... The 2 25A MCBs on the lines to the 2 SPDs should not be there. The aim of the SPD is to protect the inverter from surges on the Escom and/or load lines. these 25A breakers will trip before the 35A ones in the inverter line, thus only disconnecting the SPDs from the system, the 35A MCBs should be the ones to trip in the event there is a voltage surge, to isolate the inverter as fast as possible. I trust that makes sense, and if I am wrong, will someone please correct me ... thanks CharlieD
