====== Overbanking ====== | |
| |
//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. Overbanking is the opposite of [[electrical:solar:overpaneling|overpaneling]]. | |
| |
[[electrical:12v:deep_cycle_battery#lithium_chemistries|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). | |
| |
===== harmful effects ===== | |
| |
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]]. | |
| |
[[electrical:12v:alt_and_solar|Adding alternator charging]] or [[electrical:converter|shore power charging]] to solar can help oversized banks stay healthy. | |
