Alternator + solar charging has considerable benefits over [[electrical:12v:alternator|alternator charging alone]], and over [[electrical:solar|solar alone]]. The alternator can help a small solar install punch well above its weight, [[opinion:frater_secessus:panelsizesforinsolation|acting like a much bigger install in areas of poor insolation]].((especially with PWM)) The alternator can help meet [[electrical:12v:charging#charging_current|lead bank minimum charging current requirements]]. Solar can hold the bank at a higher state of charge, thereby reducing current demands on the alternator and allowing the use of smaller [[electrical:12v:b2b|DC-DC chargers]]. | Alternator + solar charging has considerable benefits over [[electrical:12v:alternator|alternator charging alone]], and over [[electrical:solar|solar alone]].

Note that adding alternator charging to the mix does not necessarily require a fancy, expensive isolator; in some ways [[electrical:12v:alternator#constant-duty_solenoid|the simple solenoid]] provides best bang-for-buck with the fewest drawbacks.((see the Gotchas section)) | Note that adding alternator charging to the mix does not necessarily require a fancy, expensive isolator; in some ways [[electrical:12v:alternator#constant-duty_solenoid|the simple solenoid]] provides best bang-for-buck with the fewest drawbacks.((see the Gotchas section)) |
