Hi all I am in Centurion and have been a member of the forum since August 2017. Thanks to the abundance of information here, I have learned a lot and got all of my questions answered merely by browsing around. Regarding ArtSolar panels, I bought 9 of these (72 cell 315WP) end of October 2017. They seem to perform the same as the initial 3 x Enersol panels that I had installed before upgrading my system. The specifications are identical between the 2 makes and visually the build quality appears to be the same. Considering that they are only in operation for 6 months, only time will tell their reliability. I have also installed a second parallel Axpert when the 9 panels were added. Interesting observation is that the MPPT responds much faster when the load increases than with the 3 x Enersol panels connected to one Axpert. Would this be due to installing the second Axpert, split of PV between the inverters (2 strings of 3 panels per inverter) or could it be due to the panels. Insight from one of the experts here will be appreciated.
