In the event of a fault with the unit installation, either battery or solar panel, ALL the LEDs on the unit
will flash to indicate the fault type.
Table 1.7.1:
Flashing Sequences
LED State
Description
1 flash (followed by 3.5 second off)
Internal hardware fault
2 flash (followed by 3.5 second off)
Unit under temp fault
3 flash (followed by 3.5 second off)
Unit over temp fault
4 flash (followed by 3.5 second off)
Output battery fault (Volts too high)
5 flash (followed by 3.5 second off)
Input under voltage (Battery)
*3
6 flash (followed by 3.5 second off)
Input over voltage (Battery or Solar panel)
*3 If the unit is being supplied power from the vehicle and solar simultaneously and ONE of those sources is
undervoltage, that specific source LED will flash 5 times. If the unit is being supplied power from the vehicle and
solar with BOTH sources under voltage, OR if the unit is being supplied power from one input only and that input
is undervoltage, ALL LED’s will flash 5 times.
1.8 Battery Test Mode
The unit features a battery test mode which occurs every 100 seconds. The test mode is designed
to both test that the input conditions are still met and check for the presence of a battery on the
output of the unit. This feature is designed to protect the vehicle battery from over discharge and
protect the vehicle and wiring in the event of damage to the output connection. During low output
current situations (when in Float mode for example) this battery test may take up to 60 seconds to
complete.
