+A **fractional reserve** might be a half- or quarter day of battery reserve.  This takes into account the (reduced) contributions from your solar, alternator, etc.  It may also require going into voluntary [[electrical:solar:rationing|power-rationing mode]] when solar output is very low.
+In areas with abundant and consistent [[electrical:solar:output|insolation]] like the desert southwest, you may be able to run with no reserves at all.
