Changing Configuration Settings
The following is recommended when adjusting system settings:
• Save existing configuration file
• Change the minimum set of parameters at any one time then check for expected results.
• Save new configuration file.
System Shutdown
If the system is to be left unattended with the power off:
• Turn off the inverter
• Isolate battery from the inverter.
• Isolate the solar array or other renewable from the inverter.
Your installer will provide details of how to do this.
Operating Without the Generator
If the generator is not available the following recommendations should be followed to conserve the battery:
•
TURN ON ECONO MODE
. The SP PRO will pulse the output voltage and only supply continuous voltage
when the load exceeds a defined limit. If present, renewable energy will recharge the battery.
•
SWITCH OFF THE SP PRO
when ever possible to reduce the load on the battery, allowing the battery to be
recharged even by small renewable power.
•
IF THE BATTERY BECOMES HEAVILY DISCHARGED
, the SP PRO will automatically stop supplying AC
power to the load, to prevent battery degradation or damage. Switching on the Low Battery Override
function will restore power for a time at the expense of discharging the battery even more deeply.
Note: The SP PRO internal electronics are powered from the DC (battery) side, not from the AC
(generator) side. Therefore if the battery is excessively discharged, the electronics may not be
able to start up until the battery is partially recharged, from renewable power for example.
Installer Maintenance
Other than ensuring all AC and DC connections are always tight, there are only three areas that may require
maintenance.
•
FAN ALERT
– This can be checked in the “Now” tab of the “Data View” section. A fan alert generally
indicates that the fan is stationary when it should be running. This will mean that either the fan needs
replacement or that a foreign body is stuck in the fan. Either situation is unlikely as the SP PRO is protected
against pest infestation and the fan life monitor should predict fan failure.
•
FAN LIFE
is recorded in the “Technical Data” section of the “Data View” tab (see below). Fan life is
expressed in the percentage of fan life used ie The figure starts at 0% and rises the longer the fan runs. As
fan life is projected to be in excess of 40,000 hours quite a high percentage of fan life can be used before
replacement is necessary.
•
CAPACITOR LIFE
is measured on both halves of the power module and is expressed, as before, in
percentage of life used. The power module should be replaced when capacitor life, in either half, reaches
95%.
There are no user replaceable parts within your SP PRO. Any maintenance, other than fan filter
cleaning, should be performed by a Selectronic Authorised Installer.
