 A common rule of thumb for sizing batteries to solar power relates nominal panel output in Watts to bank capacity in Ah.
-//1:1// == 200W((nominal)) solar + 200Ah battery bank.  \\
+//1:1// == 200W solar + 200Ah battery bank.  \\
-//2:1// == 200W((nominal)) solar + 100Ah of battery. ([[electrical:solar:overpaneling|overpaneling]])
+//2:1// == 200W solar + 100Ah of battery. ([[electrical:solar:overpaneling|overpaneling]])
-//1:2// would mean 100W((nominal)) solar + 200Ah of battery. (underpaneling or [[electrical:solar:overbanking|overbanking]])
+//1:2// == 100W solar + 200Ah of battery. (underpaneling or [[electrical:solar:overbanking|overbanking]])
+For solar-only charging 2:1 or even 3:1 is recommmended.
+For [[electrical:shore_power|shorepower-]] or [[electrical:12v:alt_and_solar|alternator-]]augmented charging 1:1 or 1:2 may be sufficient.
