Hey Jeff,the lph26 is rated 20-25 outlets,so if your planning on eventually 30...I called and talked with them on what I wanted to use one for,looking at the 45,and future use,and they recomended the 60 for me.Only reason I havent pulled the trigger is I'm waiting for Our season to slow down.No need to have it sit in my basement for 2-3 weeks like my RO has been doing.
