Load Short Circuit
Error status LED: Flashing red. Battery status LEDs: R/G-Y
sequencing. Fully protected against load wiring short-
circuits. After two (2) automatic load reconnect attempts (10
seconds between each attempt) the EcoBoost MPPT will
wait, and then automatically reconnect the load, once the
short is cleared.
High Solar Voltage Disconnect
Charging Status LED: R flashing. No battery status errors.
If the solar input open-circuit voltage (Voc) exceeds the 120
volt maximum rating, the array will remain disconnected
until the Voc falls safely below the maximum rating.
Remote Temperature Sensor (RTS)
Error status LED: Flashing red. Battery status LEDs: R/Y -
G/Y sequencing. A bad RTS connection or a severed RTS
wire has disconnected the temperature sensor during
charging. Charging automatically resumes when the
problem is fixed. To resume operation without an RTS,
disconnect all power to the EcoBoost MPPT and then
reconnect. If the controller is re-started with the failure
still present, the controller may not detect that the RTS is
connected, and the LEDs will not indicate a fault.
A metered model, an RM-1 meter, or MSView PC software
can be used to determine if the RTS is working properly.
Battery / Load High Voltage Disconnect (HVD)
Error status LED: Flashing red. Battery status LEDs: R-G
sequencing. This fault is set when battery voltage is above
normal operating limits. The controller will disconnect the
solar input and set a High Voltage Disconnect fault. This
fault is commonly caused by other charging sources in the
system, charging the battery above the EcoBoost MPPT
regulation voltage. Recovery occurs at HVD re-connect
threshold, and the fault will automatically clear. See Section
7 - Technical Specifications for values.
36 Troubleshooting
High Heatsink Temperature
Error status LED: Flashing red. Battery status LEDs: R-Y
sequencing. The heatsink temperature has exceeded safe
limits and the load is disconnected. The load will automati-
cally reconnect when the heatsink cools to a safe
temperature.
Battery Over-current
Error status LED: Flashing red. Battery status LEDs:
R/Y-G sequencing. While rare, if battery current exceeds
approximately 130% of the controller's output current
rating, this fault can occur. The fault is generally related
to fast, large battery voltage transients (connecting a very
heavy or capacitive load like an inverter) that are faster
than the controller can regulate, and it shuts off to protect
the circuitry. The controller will automatically re-start in 10
seconds.
Settings (DIP) Switch Changed
Error status LED: Flashing red. Battery status LEDs:
R-Y-G sequencing. If a settings switch is changed while
there is power to the controller, the LEDs will begin
sequencing and the solar input will disconnect. The
controller must be re-started to clear the fault and begin
operation with the new settings.
Custom Settings Edit
Error status LED: Flashing red. Battery status LEDs: R-Y-G
sequencing. A value has been modified in custom settings
memory. The controller will stop charging and indicate a
fault condition. After all settings have been modified, the
controller must be reset by removing and then restoring
power to the controller. The new programmed settings will
be used after the power reset.
