Resolve any issues found in steps 4 and 5 above and reconnect the output cables to the
POWERmini USB.
Audible Alarm Cancel
If the audible alarm is enabled, you can silence the audible alarm from the Status page by pushing the SEL
button and releasing after about 1 second. The audible alarm will remain disabled until you manually re-
enable it (see Figure 7 Control Settings page). The audible alarm is enabled when the asterisk is shown at
the lower left of the Status page (see Figure 8).
Solar Charger Disconnect
When a solar panel is only partially illuminated it may not provide enough voltage to charge the battery.
If POWERmini determines that the solar panel voltage is not sufficient then the solar panel input is
disconnected from the battery.
The POWERmini enables charging only when the battery is in the safe area. To prevents charging of a
possibly defective battery, POWERmini will not charge a battery at or below that voltage.
If POWERmini USB detects a solar panel output current greater than 11A the POWERmini solar input will
be automatically disconnected and the warning message “FAULT” will be displayed in the bottom of the
solar panel window. To reset the POWERmini solar input, disconnect the solar panel from POWERmini
and then reconnect it.
USB Dedicated Charger Port (DCP)
The 5V USB charge port is compatible with the requirements of the USB Battery Charging Specification
1.2. This supports different charge current limits for a wide variety of devices including most popular cell
phones and tablets. The maximum charge current is set by the device connected to the USB charger port.
This requires a standard 4 conductor USB cable. Note that if you do not use the standard cable the
charger will default to a maximum charge current of 500mA (900 mA USB3.0).
The maximum output is current limited by specification to 1.5A.
Fault reporting
The POWER LED serves dual functions. When the unit is working normally the LED is green indicating
normal operation. A fault condition is indicated by the front panel POWER LED changing color to flashing
red. Examples of fault condition are over-voltage and under voltage battery voltage.
Operating Time
POWERmini USB keeps track of the amount of time that has passed from power up time and displays the
information on the System Report page.
