Battery Roundtrip Efficiency

HOMER Logo

Type:	Input Variable
Units:	%
Symbol:	ηbatt,rt

The battery round-trip efficiency is the round trip DC-to-storage-to-DC energy efficiency of the storage bank, or the fraction of energy put into the storage that can be retrieved. Typically it is about 80%. HOMER assumes the storage charge efficiency and the storage discharge efficiency are both equal to the square root of the round-trip efficiency.
