Bottom LED Flash RED Instant Low DC Voltage Shutdown. Battery or battery wiring fault.
Solution
1. Give battery bank a full charge and equalise charge.
2. Check all battery wiring including the battery bank interconnections, connections at the DC fuse or
CB and the main battery connection to the SP PRO.
3. Check all battery sense/pro-charge wiring.
4. Check for faulty or failed cells withing the battery bank.
NOTE
: When all LEDs are flashing RED the inverter has been put in Low DC Shutdown Override by the
user. In emergency situations, this override enables the SP PRO to be forced to work beyond the battery
shutdown limits. The SP PRO will continue to operate at reduced capacity until the battery can no longer
supply enough power to keep the inverter and loads running. Please remember that this feature should
only be used in an emergency as it overrides the SP PRO normal battery shutdown protections and may
damage the batteries or connected equipment.
