Hi,
I have an existing PV system of 15 Canadian Solar 260 panels together with SolarEdge P300 Inverters and a Solaredge 3800 inverter. I want to add 11 Sunpower E19 320 watt panels with Solaredge P400 optimizers. I could do that buy adding a separate inverter the smallest 3KW Solaredge inverter or buy buying one big new inverter, maybe the 6 kw one or 7.8 KW one and run all panels on one inverter. The new system will get significant shading for some panels at all time of the day, since the panels are oriented south, west, east and two north. So I thought all on one might be better, because it would make it easier to reach the minimum voltage for the inverter to kick in. Does it matter which way I go? Two separate inverters or one unified one? There would be only two strings altogether: one from the existing system and one from the new system . Thanks for any suggestions ! Matthias
