Shutdown if Output Battery < 4V
There is a maximum 20 second delay before the charger will produce an output
any time a source is introduced into the system, this allows the unit to provide
optimum input sharing and effective battery isolation.

Error Codes
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. Flashing sequences are
described in the table below.
LED State
Description
1 flash (1 flash followed by 3.5 second off)
Internal Hardware Fault
2 flash (2 flash followed by 3.5 second off)
Unit under temp fault
3 flash (3 flash followed by 3.5 second off)
Unit over temp fault
4 flash (4 flash followed by 3.5 second off)
Output Battery Fault (Volts too high)

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.
