The Rover Elite MPPT charge controller has a reactivation feature
to awaken a sleeping lithium battery. The protection circuit of
lithium battery will typically turn the battery off and make it
unusable if over-discharged. This can happen when storing a
lithium battery pack in a discharged state for any length of time as
self-discharge would gradually deplete the remaining charge.
Without the wake-up feature to reactivate and recharge batteries,
these batteries would become unserviceable and the packs would
be discarded. The Rover Elite will apply a small charge current to
activate the protection circuit and if a correct cell voltage can be
reached, it starts a normal charge.
The image on the right shows the activation interface of lithium
battery.
Lithium Battery Activation
Equalization: Is carried out every 28 days of the month. It is intentional overcharging of
the battery for a controlled period of time. Certain types of batteries benefit from periodic
equalizing charge, which can stir the electrolyte, balance battery voltage and complete
chemical reaction. Equalizing charge increases the battery voltage, higher than the standard
complement voltage, which gasifies the battery electrolyte.
When using the Rover Elite to charge a 24V lithium battery bank, set the
system voltage to 24V instead of auto recognition. To change the system
voltage, press the Up or Down buttons then long press Right Arrow to save the
selected system voltage.
CAUTION
Equalization may increase battery voltage to a level damaging to sensitive DC loads.
Ensure that all load allowable input voltages are greater than the equalizing charging
set point voltage.
Once equalization is active in the battery charging, it will not exit this stage unless
there is adequate charging current from the solar panel. There should be NO load on
the batteries when in equalization charging stage.
WARNING
Over-charging and excessive gas precipitation may damage the battery plates and
activate material shedding on them. Too high of equalizing charge or for too long
may cause damage. Please carefully review the specific requirements of the battery
used in the system.
