HI All Apologies for the delay. Thanks everyone in replying to my question. That's great to know- and reassuring for me now using these inverters in parallel (incredible that i couldnt get a straight reply from the tech people here, but there again, i am in southern europe) I may wish to upgrade the firmware in the future, do you guys know how to do that? Thanks again Larry

HI Forum This is my first post on this forum- I usually use wind Forum in the states- but you guys in SA seem to be installing alot of Voltronic/MPP Axpert type inverters. We've recently been installing these hybrid inverters (same manufacturer with different sticker) here in Spain. Surprisingly the amazing technical service here is not able to tell me on how the inverters work in parallel My question is for 2xAxpert 5kVA in parallel, when programming parameters 02 and 11: A)) Do you control the Maximum charge current (02) and Maximum utility charge (11) from just the Master? Or B)) Do you control them by programming the Master and the Slave and you take the resulting sum from both inverters? I think this has been mentioned in this thread, but I want to make 100% sure that I understand correctly Any help greatly appreciated Larry
