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. | A **fractional reserve** might be a half- or quarter day of battery reserve.

[[electrical:solar:overpaneling|Overpaneling]] [[electrical:solar:panel-bank_ratio|2:1]] or more will help gather more solar energy when running slim reserves in poor insolation. | |

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. | 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. |
