 There will generally be more "surplus" power available when using MPPT charge controllers v. PWM,((http://forum.solar-electric.com/discussion/comment/372165#Comment_372165))((http://forum.solar-electric.com/discussion/comment/250746#Comment_250746)) though the difference is less dramatic during periods one would run opportunity loads (see [[electrical:solar:nonessential#when_to_run_opportunity_loads|below]]).  Siphoning off power can actually **help PWM controllers run cooler** by reducing the ON-OFF switching activity that generates heat.
+[[electrical:solar:overpaneling|Overpaneled]] systems have even more excess power available.

 The most precise way to do it **automatically** is to use a charge controller which turns on the LOAD output only when the batteries are in Float stage.  Charge controllers with this feature tend to be expensive.
+You can also build a Pi or similar that talks to the controller over its communication port/protocol and checks when the controller is in Float.
