Periodic Equalise
. Battery banks used in cyclic applications may, over time develop
charge (and voltage) imbalances and may require an “equalise” charge . How often an
equalise occurs is set using
Equalise Period
. The equalise charge voltage, current and
duration are set in the CHARGER tab. (See “Charger Settings” section)
When an equalise charge is carried out by a charging source that is external to the
SP PRO (i.e. DC coupled solar or wind sources) the SP PRO monitors this and
reschedules its equalise. For the SP PRO to reschedule, the battery voltage must be
taken to or above the
EQUALISE STAGE
voltage for the
EQUALISE TIME
settings
in the SP PRO therefore it is important to match or slightly exceed these setting in the
external renewable controller.
Periodic Recharge
is for systems that remain on Float charge for long periods of time
such as Solar Hybrid or Boats in Marinas. Battery banks operating in these conditions
benefit from periodically being put through a full charge process. When enabled, after
remaining in Float for the number of days set by the
Recharge Period
, the SP PRO will
return to Initial charge stage.
Soft Battery
setting is only available when Custom Battery Type is selected and is for
battery banks that are “soft” meaning they have a relatively high internal impedance.
Useful with aqueous type battery technologies or battery banks with high internal
impedance. Technically this function is achieved within the SP PRO by reducing the
gain of the battery charger’s voltage control loop thereby increasing the damping of said
loop. Settings are Softness 1 to Softness 6 with Softness 6 being the “softest” setting.
This setting is only effective with battery technologies that have an
inherently high internal impedance such as aqueous type technologies.
Using this setting with serviceable lead acid or lithium battery technologies
may cause unintended charger operation and in some cases over voltage
shutdowns.
Mid
Point Monitoring
is a function designed to highlight any significant voltage
variation between one half of the battery bank and the other. If one half of the bank is
lower than the other it may suggest that the batteries need an equalisation charge or,
perhaps, that there is a cell in one half that is not performing correctly. In
Mid Point
Range
you determine how much variation between the two halves you will allow before
notification. With this function you can help predict battery problems. To make use
of this feature you will need to install an additional wire to the battery, see installation
section for details. We recommend the use of this handy feature.
Often these problems can be solved by an equalisation charge so we have included
provision for you to request such a charge by enabling the
Equalise Request
setting
.
Peukert’s Exponent
is a legacy setting and is not required in SP PRO firmware
versions 7.06 and greater. The firmware now intelligently learns and compensates for
the battery performance resulting in a more accurate SoC calculation.
OVER TEMP. PROTECTION
This feature reduces the charge current automatically as
the battery temperature rises above the temperature specified in
Limit Charge above
.
It reduces the charge current by the
Limit Rate
for every degree Celsius that the
temperature is above the temperature specified.
With the default settings the charge rate will drop 10% for every degree over 45
°
C. e.g.
no charging current at 55
°
C.
