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, 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 the Troubleshooting section 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 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 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
