[QUOTE="binky, post: 537298, member: 490"] Your string voltages should be fine, quick Google says 30v per panel and the Solis is 90v start up. However, the orientation SSE means that string will shut down earlier, and only being 4 panels is going to struggle to get going and keep going in lower light levels. Your panels are also slightly less efficient. So I suspect there is nothing wrong bar the fact that with recent gloomy weather your system struggles more to get going. Something you could check on the inverter display is the string voltages [/QUOTE]
