Looking at the 6k Transformer based inverter/charger. Have a well pump that needs to be run only in emergency situations that a pair of SPF3000 in split phase probably can't run (42a starting needed for pump). Reviewing the instructions, not sure how you get split phase of of this as there is no specific graphic for it. Options are N+L1 OR N+L2 for 120 or L1+L2 for 240. My goal is to run this to a sub panel and would expect L1+N+L2 to the panel to get both 120 and 240 split phase. Am I missing something?
