G. Charger Information
G.1.1 Charging Cycle
The fully automatic Invertek Battery Charger is adjusted at the factory so
that most lead-acid and lead-gel batteries can be charged to the maximum,
As soon as the minimum AC voltage is available at the AC input (“AC IN” LED is
lit),the Battery Charger is switched on automatically (“CHARGER” LED is lit). The
battery is automatically charged to match the pre adjusted voltage levels and
charge current. Thanks to the Invertek sophisticated and intelligent Floating Charge
System, the batteries can be left in charge mode for unlimited time.
During the charging cycle, the AC loads are continually supplied with power from
the incoming AC voltage source. (“AC OUT” LED is lit).
The charger functions are shown in the following diagram:
G.1.2 Equalization charging (P-04):
Equalization charge is a higher voltage applied to the batteries for a specified
period of time.
Equalization mode should never be used when using Gel-Batteries
Before you program the Invertek for Equalization-charge you must confirm with
your supplier that the batteries are suitable for this process.
Equalization is recommended for lead-acid batteries in order to mix the electrolyte
fluid and to clean the lead plates of the batteries.
If the Invertek is operating with a lead-acid battery which is suitable for
equalization, set the P-04 is “ENABLE”. In this setting, at every 25 charge cycles an
equalization cycle will be carried out for 2 hours (factory setting). During such a
charge cycle the “Equalize” LED lit. During a Charge cycle, equalization can be
started independent of the actual programming.
CAUTION: During the equalization process, the batteries will produce a lot
more gas.
DANGER OF N EXPLOSION!!
G.1.3 Input current repartition (Power sharing)
To manage the power available on the AC INPUT the Invertek is equipped with a
system usually called “Power sharing” or INPUT power distribution. With this
feature it is possible to limit the AC INPUT current assigned to the charger. The
more current used by the AC load, the less power is given to the charger. Priority
for the AC Loads. When power sharing is used the red 200% LED on the power
monitor is lit to show that the battery charging is being limited.
