I have a Renogy 100 watt solar suitcase and two Renogy 100 watt panels. If possible, I'd like to wire them in parallel and run them through my Renogy contoller. The suitcase is wired in series which to me is the same as a 100 watt panel. Renogy says I can't do it but didn't really say why. At least I didn't understand the explanation. The specs for the suitcase and 100 watt panels are similar but not exact. Open Circuit Voltage is the same = 21.6V. Short Circuit Current is a bit greater on the panels = 6.14A vs 6.1A. Optimum Voltage and Current is slightly greater on the individual panels.
So If I can't combine the suitcase and panels I'd like to buy another 100 watt panel. However, the new Renogy 100 watt panels have slightly different specs than the ones I have. Voltage is higher but current is lower. So isn't this the same problem? And if so, how does anyone combine dissimilar panels?
