97-0019-01-01 57 Configuring the F reedom SW using the SCP Resetting the Freedom SW to Default Settings The Restore De faults command returns the Freedom SW to factory default settings. After using the Restore Defaults command, the Freedom SW is no longer config ured for the power system.
58 F reedom SW Owner’s Guide Battery Charging Refer ence This section describes the multistage charging algorithm (formula) of the Freedom SW. Battery T ypes Freedom SW char ges flooded (or wet) lead -acid, Gel, AGM (absorbed glass mat), and custom batteries.
97-0019-01-01 59 Battery Charging Reference The charging cycle is a multi-stage (three-stage) proc ess. Whenever qualified AC power is present at th e inverter ’ s input, it passes power through to the connected load and begins charging the batteries.
60 F reedom SW Owner’s Guide Battery Charging Reference Absorption Stage During the absorption stag e, the Freedom SW begins operating in constant voltage mode and the current falls gr adually as the amp hours are returned to the battery . By default, the bulk and absorption voltage settings are the same for all battery types.
97-0019-01-01 61 Battery Charging Reference T wo-Stage Charging Process T wo-stage (or no float) mode differs from an ordinary three-stage charge mode in that it does not continuously maintain the battery at float voltage. Instead, the Freedom SW begins char ging the battery in bulk mode whenever the battery voltage drops be low the recharge level.
62 F reedom SW Owner’s Guide Battery Charging Reference NO TE: When the char ge cycle is interrupted, the char ger will restart charging at the beginning of the multi-stage algorithm. Exit Current Threshold can be effe ctively disabled by programming the amp-hour capacity to the minimum.
97-0019-01-01 63 Battery Charging Reference Equalize Charging Many battery manufacture rs recommend periodic equali ze char ging to counter cell charge imbalance and capacity-robbing electrolyte stratification. Equalizing helps to improve battery performance and lifespan by encouraging more of the battery material to beco me active.
