Operation
4.5 Protections, Faults & Alarms
The TriStar MPPT 600V protections and automatic recovery are important features that ensure
the safe operation of the system. Additionally, the TriStar MPPT 600V features real-time self
diagnostics that report Fault and Alarm conditions as they occur.
Faults are events or conditions that require the TriStar MPPT 600V to cease operation. A Fault
usually occurs when a limit such as voltage, current, or temperature has been surpassed. Fault
conditions are indicated with unique LED sequences and are also displayed on a TriStar Meter,
and in MSView software.
Alarms are events or conditions that may require the TriStar MPPT 600V to modify operation.
Alarmsarecommonlyusedtoalerttheuserthatthecontrollerisnearingaspecicvoltage,cur-
rent, or temperature limit. Alarm conditions are only displayed on a TriStar Meter, and in MSView
software.
Some basic Fault and Alarm conditions are reviewed below.
Protections
Solar Overload
The TriStar MPPT 600V will limit battery current to the Maximum Battery Current rating. See
Figure 9-1 - Battery Current vs. Array Voltage de-rating graph - in Section 9.0. An over-sized
solar array will not operate at peak power. The solar array power should be less than the
TriStar MPPT 600V Nominal Maximum Input Power rating for optimal performance.
Solar High Input Voltage
Solar input current will be limited as the array open circuit voltage approaches the 600 volt maxi-
mum input voltage limit.
High Temperature
The TriStar MPPT 600V will limit the solar input current if the heatsink temperature exceeds safe
limits. Solar charge current will be tapered back (to 0 amps if needed) to reduce the heatsink
temperature.
Faults
Remote Temperature Sensor Failure (R+Y / G+Y)
If a fault in the RTS (such as a short circuit, open circuit, loose terminal) occurs after the RTS has
beenworking,theLEDswillindicateafailure.However,ifthecontrollerisrestartedwithafailed
RTS, the controller may not detect that the RTS is connected, and the LEDs will not indicate a
problem. A TriStar meter or the PC software can be used to determine if an RTS is detected and
working properly.
