Service and Maintenance
Multiple Sources of Supply
Hazardous voltages and energy are generated by and are fed into the SP PRO by external wiring from
multiple sources and may be stored in capacitors after the unit is switched off. Ensure the isolation of
all energy sources, including AC Source isolator, battery main isolator, battery pre-charge isolator and
all renewable energy sources (including solar, wind and hydro) before carrying out maintenance on the
SP PRO. A time of at least 5 minutes must elapse
after
the disconnection of the battery main isolator
and the battery pre-charge isolator before any trained technical staff gain internal access to the
SP PRO.
Cleaning the Fan and Fan Filter
Ensure the fan is stationary, i.e. not running.
Remove the four retaining screws that hold the fan filter in place.
Clean the filter mesh with a soft brush or similar implement.
Check to see if there is any foreign matter that could impede the fan’s operation.
Replace the filter and tighten the four retaining screws.
All other maintenance on the SP PRO should be performed by a suitably qualified installer.
Above the fan filter is a safety grill. Do not remove this grill – fast-moving fan blades can cause injury.
Monitoring the operation of the SP PRO
Monitoring of the power system will give early warning of any system issues and avoid unexpected system
shutdowns. A system may be monitored locally and remotely by adding an optional Select.live device.
It is Good to Keep an Eye on the Following:
Battery SoC%
– this is the fuel gauge for your battery. It lets you know how much energy you have available
now. A high average figure means good battery life.
The average Load kWh
– check that this is within the system design parameters. An increase in the site Loads
may mean a longer generator run time or extra energy taken from the grid.
Solar
– indicates how much energy is being provided by your installed PV. If this is lower than expected then
there maybe an issue with your PV panels or solar controller.
Grid import
– indicates how much energy taken from the grid. In an Off-Grid system this shows the energy
provided by the generator.
Events
– check to see how the system is operating. Each event is self explanatory. If in doubt, look at the
events in SP LINK >

System Shutdown and Startup
The installer will provide detailed shutdown and restart instructions specific to the installation.
Installer Maintenance of SP PRO
Other than ensuring all AC and DC connections are always tight, there are only three areas that may require
maintenance.
Fan Alert

Fan Alert
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 a foreign body is stuck in the fan.

Fan Life
is recorded in the >
Data View
>
Technical Data
>
Fan Life
Fan life is expressed in the percentage of fan life used. The figure starts at 0% and rises the longer the fan runs.
As the fan only runs during high loads and fan life is projected to be in excess of 40,000 hours, many years of
fan life can be expected before replacement is necessary.
Capacitor Life
is measured on both halves of the power module and is also expressed in percentage of life
used. The power module should be replaced when capacitor life, in either half, reaches 95%.
There are no user serviceable or replaceable parts within the SP PRO. Any maintenance, other than fan
filter cleaning, should be performed by a suitably qualified installer.
