<<Just curious, what is the output percentage that you have your cell on and how many hours a day is the pump running? Are any of the lights on the unit on?>>

hi, output percentage has been at 90 percent (actually, when you click the readout a few times to get the actual readout, I believe its actually at 98%) since startup 3 weeks ago. Pump/filter running 9am - 5 p.m. The only lights on are the 2 green lights ("generating" and "power" or whatever) Nothing blinking or anything.
