1 INTRODUCTION
Storage Mode
Storage mode is designed to charge the house battery to its optimal level and maintain that level while
your travel trailer or RV 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 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 the Troubleshooting section (3.7) of this manual.
Unlike Touring mode, Storage mode does not continue to cycle through charge profiles. This means that
when the charging process is completed, The Manager30 in Storage mode will always remain in either
Float or Maintenance stages. Float stage provides the house battery with a ‘trickle’ charge whenever the
house battery voltage drops below a predetermined threshold, to ensure that 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.
Valid charging sources for The Manager30 while in Storage mode include AC Shore Power and Solar.
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.
NOTICE
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.
