Then solar probably isn't the best choice as sole (or even main) [[electrical:12v:power_mix|source of charging]]. But if that's situation we are in there are some approaches that might help you limp through. | Then solar probably isn't the best choice as sole (or even main) [[electrical:12v:power_mix|source of charging]].

The strategies below will work better with [[electrical:12v:drop-in_lifepo4|LiFePO4]] than lead since LFP does not suffer from [[:psoc|partial states of charge]]. | The strategies below will work better with [[electrical:12v:drop-in_lifepo4|LiFePO4]] than lead since LFP does not suffer from [[electrical:12v:psoc|partial states of charge]]. |

If you are hiding in shade because of heat you may find a spot where you get full sun until it warms up then shade in the afternoon. You might collect enough power during that time to make it to the next morning. [[electrical:solar:rationing|Reduce demand]] as needed. | If you are hiding in shade because of heat you may find a spot where you get full sun until it warms up then shade in the afternoon.

Running portable panels that you can set up in forest openings (long extensions). These would go on a separate controller. Their controller allowing, the portables would benefit from series wiring to [reduce current on the long extensions](https://rvwiki.mousetrap.net/doku.php?id=electrical:12v:voltage_sag).^1 | Running portable panels that you can set up in forest openings (long extensions).

* [[electrical:12v:alternator|Alternator charging]] might fill the gap for campers who drive to town fairly frequently. This is a scenario where [[electrical:12v:b2b|DC-DC charging]] might be preferable. | * [[electrical:12v:alternator|Alternator charging]] might fill the gap for campers who drive to town fairly frequently.
