SOLAR CHARGEMASTER MONITORING
The first thing to do every time DataControl has
started up, is reading the data from the Solar
ChargeMaster.
Figure 5-5: Read from charge controller
5.3.1 State and Current Values
As soon as the Solar ChargeMaster data has been
read, the status screen shows an overview of
important data.
Switching between the different windows of the
program is accomplished by clicking the buttons on
the left side of the screen. (i.e. Status, Current
Values, …, Menu Setting, Night Light).
Figure 5-6
The table explains the Status variables
Variable
Description
Battery voltage in V
Battery voltage at the moment, in V
Battery type
Liquid lead acid (wet battery) or GEL
Low voltage
disconnect current
compensated in V
The voltage at which the load should be disconnected from the battery to protect it from
deep discharge (Low Voltage Disconnect). The value is shown in the same screen.
Night light function
Load settings for the nightlight function. See section 7.1 for more information.
System Performance
