Request Battery Equalise
The BATTERY EQUALISE display shows whether the SP PRO will perform an equalise
charge when it next achieves Float (Equalise Pending). Pressing the button will toggle
between Equalise Pending and No Equalise Pending. Pressing the button will also stop
a current Equalise process.
Setting Charge Efficiency Index
The Charge Efficiency Index will automatically adjust itself in the SP PRO but a number
of faults in the installation could cause it to become erroneous (including poorly calibrated
or installed DC current shunt or failing batteries). For a correctly installed system with
new batteries the index should be between 0.900 and 1.000. If it is a long way out of
range, rectify the system fault then reset it back to 0.950.
Zero Shunts
To accurately measure and calculate inputs and outputs to and from the batteries the
SP PRO needs to start its measurements knowing what is Zero. To set this parameter
you must ensure all inputs and outputs are switched off – that is no solar, wind or other
inputs coming into the system and all DC loads are switched off – then the ZERO
SHUNT 1 and ZERO SHUNT 2 buttons should be pressed.
The figures above the buttons indicate what the on board computer in the SP PRO
perceives the relative current to be before zeroing.
Fan Type
The cooling fan within the SP PRO is a long life, high quality component. As the control
section of the SP PRO calculates the hours of life left in the fan (along with other
components) it is important that the fan – when it is eventually necessary – is replaced by
an authorised spare part. However we are aware that components become obsolete and
other fans may need to be used, so we have allowed settings for 4 different fan types.
These settings are based around all the fan types available at this time and we will clearly
mark any replacement fans with their fan type as they become available.
Expansion Card
The current status of the EXPANSION CARD is displayed. The SP PRO can be set
to use (Enabled) all the connected functions from the expansion card like shunts and
battery temperature sensor or to ignore (Disabled) them. By default the Expansion Card
is enabled.
