1 INTRODUCTION
Storage Mode
Storage mode is designed to charge the house battery to its optimal level and maintain
that level while your caravan is in storage. This mode requires a valid charging source
(240V or solar and all loads to be switched off or disconnected from the house battery
before charging. It uses a 8-stage* charging profile consisting of Desulphation*, Soft
Start, Boost, Absorption, Battery Test, Equalise**, Float and Maintenance stages (see
Figure 1.5.2). Storage mode is designed to detect a wide range of battery fault conditions,
for more information on these fault conditions, please refer to section 3.6 ‘Fault Display’.
Unlike Touring mode, Storage mode does not cycle through the entire charge process.
When the charging process is completed, The Manager30 will always remain in either
Float or Maintenance stages. Float stage will provide the house battery with a ‘trickle’
charge whenever the house battery voltage drops below a predetermined threshold to
ensure the battery stays charged. Maintenance stage turns The Manager30 output off,
but continues to monitor the House Battery and will revert to Float stage when the House
Battery drops below 12.7V (12.8V for Lithium) for 5 seconds or below 90% SoC for 1 hour.
NOTE: If The Manager30 is set to Storage mode and the vehicle is started The
Manager30 will automatically switch to Touring mode once it senses an increase in
input voltage from the alternator.
When using the charger in Storage mode, make sure that there is a valid charging
source and that all loads are disconnected from the house battery. Failure to do so
may cause the house battery to be under charged, give false readings on the State
of Charge indicator and possibly cause damage to any loads connected.
*The Lithium profile does NOT incorporate a Desulphation stage.
**The Lithium, AGM and Gel profiles do NOT incorporate an Equalise stage
