Thank you, yes, I was reading the AC input voltage off the display. I was assuming that the panels were connected in series but now that you've mentioned it, my panels are stacked 5 in a row.

Thank you so much for the reply. According to the quote I received from the installer it only shows: 330W Canadian panels but more information than that about the panels I do not have, ☹️. It does appear to be an Axpert or so again the quote suggests. Unfortunately I did not do the installation and or purchase the products to have any more information. I can however provide images of the inverter (once the sun comes up). Only 05:00 AM here in SA. I do have 10 of the 330W panels in series on the roof and the PV input voltage fluctuates between 239 - 240 V at any given moment.

Can anyone please assist me? I have a Mecer 5kVA inverter that keeps on tripping the power and giving me a error code 11 - "Main relay failed". Is this something that can be rectified by playing around with the settings or does it just mean that the inverter is on its way out?
