Xantrex Technology HF 1800 Charger Output Current vs. AC Input Voltage, Table A-1Charging Voltage

Charger Output Current vs. AC Input Voltage

Charger Output Current vs. AC Input Voltage

When the Freedom HF is charging batteries from a weak shore power source the AC voltage may fall as the Freedom HF draws current. To reduce the chance of the shore power voltage collapsing below the configured transfer level the Freedom HF will reduce the charging current at low shore power voltage according to the following graph:

Freedom HF 1000		Freedom HF 1800
20A		40A
16A		32A
90V	105V	135V
