[QUOTE="Powerguy, post: 546257, member: 35663"] Hi there , I’m no expert but researched this a bit when I fitted a 16kw solar system up . VOC is what you need to look at on the inverter , voltage open circuit . my panels had a voc of 44.1v each , inverter was 450 voc so I split my strings so as not to got over this ,panels can do 5-10 percent more voltage than stated this was taken into account too. Your 23 panels at 390 w will if at full power make 8970w taking it over your 8000w limit but maybe your optimisers turn this down I haven’t much knowledge on optimisers hope this helps [/QUOTE]
