Since you installed PVC conduit and a LB outside why wouldn't you just continue it to the panel and not use the cable. Just one elbow and a short piece of pipe
That's how I prefer to do it, but... "Ron, make sure you use up that extra SE we have laying around the shop for that service you're doing."
"Ok, boss."
As far as the spacing for the condensing units, wouldn't that be an issue for the HVAC man? It's very rare that I see CU's spaced further than 24" from the outside wall. Very rare.
