-Overbanking means having a battery bank oversized compared to available solar-only charging power+//Overbanking// means having a battery bank oversized compared to charging power (particularly in solar-only scenarios)
-The [[electrical:solar:panel-bank_ratio|solar:battery ratio]] might be something like 1:2.+The [[electrical:solar:panel-bank_ratio|solar:battery ratio]] might be something like 1:2.  Overbanking is the opposite of [[electrical:solar:overpaneling|overpaneling]].
  
 [[electrical:12v:lifepo4_batteries_thread|Lithium]] chemistries are not bothered by partial state of charge so overbanking is a non-issue for them.  The camper might have a lot of lithium capacity to take advantage of [[electrical:12v:alternator|alternator charging]] or [[electrical:shore_power|shore power]] charging (via [[electrical:converter|converter]] or stand-alone charger). [[electrical:12v:lifepo4_batteries_thread|Lithium]] chemistries are not bothered by partial state of charge so overbanking is a non-issue for them.  The camper might have a lot of lithium capacity to take advantage of [[electrical:12v:alternator|alternator charging]] or [[electrical:shore_power|shore power]] charging (via [[electrical:converter|converter]] or stand-alone charger).

 +Problems can crop up when a 'dweller unintentionally overbanks:  "Hi guys!  I just bought 400Ah of AGM batteries and a 100w solar setup!"
  
 +Unintentionally overbanked designs are also found where a 'dweller wants to run large [[electrical:inverter|inverter]] loads and forgets how much power it takes to **recharge the batteries fully every day**.  Failure to recharge fully leads to [[electrical:batterycide|battery murder]].
