[[electrical:12v:alt_and_solar|Alternator & solar charging]] enhance each other when used together. Adding alternator charging to solar can significantly reduce [[electrical:solar:sizing|the amount of solar required]] to meet your needs. | [[electrical:12v:alt_and_solar|Alternator & solar charging]] enhance each other when used together.

Note: So-called [[lifestyle:faq_solar_generator|solar generators]] **do not generate power**: they are battery banks, usually AGM or lithium. See below. | Note: So-called [[lifestyle:faq_solar_generator|solar generators]] **do not generate power**: they are battery banks, usually AGM or lithium. See below.
