7.1. Error and Warning codes
This appendix gives a list of error and warning codes and possible solutions.
E0: Calibration failure
Internal malfunction – calibration data failure/missing
• Contact dealer for support – Fault is not user correctable and SBP requires replacement.
E1: Short circuit
Short circuit protection is activated in the event of a short circuit, an overload condition or excessive inrush current - such as when
attempting to directly power an inverter or inverter/charger.
1. Check for a potential short circuit condition.
2. Confirm that the load current draw does not exceed the SBP current rating.
3. Use the SBP to control the remote on/off switch on loads with high inrush currents, rather than directly powering/
disconnecting the DC supply.
4. Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation.
P2: Over temperature warning
Urgent intervention required to prevent load disconnection.
Internal temperature close to the limit. Over temperature protection will be activated if temperature continues to rise.
E2: Over temperature
Over temperature protection is activated in the event of excessive internal temperature.
1. Confirm that the load current draw does not exceed the SBP current rating.
2. Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation.
3. Do not install the SBP unit in a location exposed to high temperature or radiant heat - relocate SBP to a cooler position or
provide additional active cooling.
P3: Under voltage warning
Urgent intervention required to prevent load disconnection.
Under voltage protection will be activated in 90 seconds if no action is taken.
E3: Under voltage
Under voltage protection is activated in the event that the input voltage drops below the under voltage limit selected for 90
seconds.
1. Switch off/disconnect loads and recharge the battery.
2. Check charging system and battery for proper operation.
E4: Over voltage
Over voltage protection is activated in the event that the input voltage exceeds 16V (for 12V systems) or 32V (for 24V systems).
1. Confirm the configuration of all charging devices in the system - particularly system voltage and charge voltage settings.
2. Check charging system for proper operation.
3. Confirm SBP system voltage configuration is correct.
E5: Configuration failure
Internal malfunction - configuration data failure/missing.
To recover the SBP from this condition;
1. Reset the unit to factory defaults under - Settings > More options > Reset to defaults
2. Disconnect all power and wait 3 minutes before reconnecting.
