SP PRO Firmware Update Procedure
Introduction
This procedure provides instructions for updating the SP PRO operating program or Firmware.
This only needs to be performed if you have been specifically requested to update the
firmware. The firmware is updated using SP LINK and can be updated either on-site or
remotely.
Requirements
Install the latest version of SP LINK BEFORE updating the SP PRO firmware.
The latest SP LINK is available at
recently released firmware.
State of Charge (SoC)
The SP PRO defaults to 85% SoC after every restart or reset. The SP PRO must reset after the
update for it to use the new firmware. It is a good idea to record the present value of SoC so
that afterwards the SoC can be re-entered using the Reset SoC function under Service Settings.
Before updating firmware
After the latest version of SP LINK has been installed on your PC start SP LINK and connect to
the SP PRO. It is recommended that the current configuration settings be downloaded from the
SP PRO inverter and saved to your site file before updating the firmware. This can be done by:
1. Connect to the SP PRO.
2. Select the Configuration Settings tab.
3. Click the Get SP PRO's Configuration button.
4. Save Configuration settings. ("File", "Configuration Settings", "Save")
