Hi wrenches, I've got a service call that needs a ~50kVA inverter, 3 phase (could be 208 or 480) I'm replacing an older system, and the existing stringing is set up with: 3 strings, with each strings calculations ending up at: ~359Vmp (Hottest Conditions) -510Voc (Cold) 40A Imp, 42.8A Isc
So, I'm hitting 2 issues: (A) Vmp too low for many newer inverters (B) Newer inverters want to land each string individually, and this system merged the strings in DC Cominers at the array, so I would prefer to give the 40A input to 1 terminal if possible to avoid a 300' repull. (I have 3 pairs of #4, and would have to repull 15 pairs of #10. It's possible, but not preferred) If anyone has a brand of inverters I should investigate that may work, please let me know. Thanks, Travis -- Travis Knipple Senior Engineer Hudson Solar Solutions LLC Rhinebeck, NY 12572 518-539-8040 x408 | [email protected] PVIP# PV-111821-013612
