The regulatory maximum for continuous AC loads is 80 of the breaker rating that the loads are connected to The Conext SW senses pass through current going to the AC load The difference between the pass through load and 80 of the Power Share setting is the current that is available for charging the batteries For example ifthe AC input ofthe Conext SW is from an AC panel with a 30 amp breaker the Power Share setting on the SCP should be selected as 30 amp Based on this the charger will control the charge current so that the total current draw is equal to or less than 24 amps in this case Should the load current be more than about 24 amps the charger output will reduce to zero 0 amp but the Conext SW will continue to supply power to the loads The Conext SW will continue to pass through power to the loads even if the load current exceeds the Power Share setting In this case it will be up to the user to remove disconnect loads if tripping the AC input breaker supplying the Conext SW is to be avoided 975 0636 01 01 Rev B Inverter Charger Operation using the System Control Panel SCP Inverter Charger Operation using the System Control Panel SCP This section contains detailed information and procedures for using your Conext SW in conjunction with the SCP If you re using the SCP to operate or monitor the status of the unit you may also refer to the System Control Panel Owner s Guide A WARNING LIMITATIONS ON USE D
