[marc8]

Hi all
been called out twice now few months ago, 1st call out was no power on one of the inverters, replaced isolator power back on, 2nd call out been round inveter showing 104 lack of power, checked new isolator ok has power also other inveter is looped out of the supply & it is working,
at 2pm today front inveter running 12 panels showing 55w, rear inveter 15 panels not running.
Least & west split, East front which is working, bright day no overcast & no shading,
turned off power back on both ac & dc, went through checks & then went low power anything to check going back tomorrow to check strings ect?
Other inveter with 12 panels working ?

Check the ampage by disconnecting the positive and negative feed from the inverter plug together and test with your clamp meter... turn dc isolator off first before disconnecting. Use your light meter point in the same direction the panels are facing take the reading and calculate both and compare with the information you would have on what each painless produces and you can tell if there is a string down

Hi All
Spoke with technical new inverter on way, IG15 no way to set country code factory set, also code 103 or any 100 up code is an ac code, if ac is getting to inverter on 103 code then its the inverter.
