Charge Controller Conguration and Software Setup
A standard unit comes pre congured with the following default settings:
• Standard (nominal battery voltage) 24.0 V
• Bulk absorption voltage 28.8 V
• Float voltage setting 27.2 V
• Battery Amp-Hours rating (AH) 100 AH
However the SolarMax is user programmable for (24 – 72) V nominal batteries. If the settings
need to be changed or the unit requires a fresh installation, the unit must rst be connected to
a computer using the RS232 serial port. If your computer or laptop does not have a serial port,
a usb to serial converter will be required. They are readily available at any computer store.
The computer must have the SolarMax Power Wizard software installed. The Software for
SolarMax consists of two les. The rst is a Windows only executable named SolarMax.exe.
The second le is a conguration le that contains all the setup values for the SolarMax unit.
The conguration values can be changed by the software.
Wherever the two les are located a Data folder and a Logs folder are created to hold the
data logging les and logging le respectively. The folder structure should look like this:
C:\Program Files\ASW\SolarMax
Data Logs SolarMax.exe
SolarMax_Conguration.pty
The rst time you start the Software, you need to have the serial cable connected to a
powered SolarMax. The program will test all the serial ports on your PC to nd the one
connected to the SolarMax
