February 9, 20251 yr Hi all, I apologise if this sounds very basic but the spec sheet of the Solis Inverter confuses me. I cannot get a read on it. The Spec sheet says 32A/20A as the maximum input current. The Inverter has 2MPPT Input and 3 Input String Number. My question is, is the max input string on each PV input 32A? Thanks in advance
February 9, 20251 yr PV1 + PV2 = MPPT1 = max 32A total. Intended for east+west arrays combined. PV3 = MPPT2 = max 20A. For main North or South array. BTW: on the bottom of a physical inverter the PV1 + PV2 should be grouped in a square symbol. Aren't they? Edited February 9, 20251 yr by Youda
February 10, 20251 yr Author Many thanks. This was my initial thought but the grouping got me all confused. From the picture, it is clearly not. I am awaiting response from Solis to truly see if PV1 and PV2 are grouped. Many thanks once more. You have clarified it for me perfectly. I have got a couple of bifacial panels and current from the 585W ratted panels can push 20A+ . I have heard the Solis Inverters do not react well to over current somethings. So wanted to make sure I am well clear of that.
