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 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, Equalize*, Float and Maintenance stages (see Figure1.4.2).
Storage mode is designed to detect a wide range of battery fault conditions, for
more information on these fault conditions, please refer to the Troubleshooting
section of this manual. Unlike Touring mode, Storage mode does not cycle. This
means that 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 necessary.
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 all loads are disconnected from
the house battery under charge. 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.
