Hi Wrenches,
I have a client with a small system consisting of 6 SunPower 230s and a SMA SB 3000. Anyway, he wants to add another 6 modules but the closest we can get from SunPower these days is a 245. The new six modules would go on a second string. Do you think that the slight difference in tracking voltage and current will be significant enough to justify the cost of adding or swapping the inverter? Here is the info for the modules: SunPower 230 WHT Vmpp 41.0 V Impp 5.61 A Voc 48.7 V Isc 5.99 A SunPower 245NE WHT Vmpp 40.5 V Impp 6.05 A Voc 48.8 V Isc 6.43 A I imagine that the tracker in the Sunny Boy will be a little off and perhaps the result will be that both strings will be running a few percent lower than they are capable of? Best, August *August Goers* Luminalt Energy Corporation o: 415.641.4000 m: 415.559.1525
