I have 3 mismatched panels where voltage is 1500v vs 7 x JA panels 1000v, amps voc etc are similar. The 10 panels are all on a platform without shading all south facing lenghwise at 15 deg elevation. At the moment Marekp correctly identified the layout but now no shading but 3 different panels i am wondering if they should remain in series 5 x 2 or is it benficial to put in 3 odd ones in para string of 3 and 7 as a string in series. Currently the easysolar gx II 48v 3k/250/70 (35) is wired before the inverter with 32a/200v and an spd but wonder if too low on voltage have inline 15a/1000 om each string on the Ja 380/logi 370 and a shokkty diode on both too, Y connectors to 2 poles - pylontech x 2 / 3000 and 40a AC connection for mains unit
