De-sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you
do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what
it does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries, nor if the batteries have been
left discharged so low that they will not accept a charge. As the saying goes, desperate diseases must have
desperate remedies. This cycle is a very high voltage charge cycle especially designed to try to break down
the sulphated crust that is preventing the plates from taking a charge and thus allow the plates to clean up
and accept a charge once again.
Warning!
The de-sulphation charging should not be carried out on batteries with good conditions.
For Sigineer Power’s model of APC6024D and APC6048D Inverter chargers, the battery type selector
position of “9” is customized with special charging algorithm for lithium battery modules from Tesla Model
S.
The algorithm has only Bulk Charging (Constant Current) to charge the battery, when the battery is charged
to high voltage alarm, the charger will shut off and inverter goes to battery mode.
