Protection Behavior
When PV shot circuit occurs, the controller will stop charging.
Clear it to resume normal operation.
The controller will limit the battery charging current to the
maximum battery current rating. Therefore, an over-sized
solar array will not operate at peak power.
if the PV voltage is larger than maximum input open voltage
100VDC. PV will remain disconnected until the voltage drops
below 100VDC.
If the current exceeds the maximum load current rating 1.05
times, the controller will disconnect the load. Overloading
must be cleared up by reducing the load and restarting the
controller.
If the temperature of the controller heat sink exceeds 65,
the controller will automatically start reducing the charging
current. The controller will shut down when the temperature
exceeds 85.
The controller will not operate if the PV wires are switched.
Wire them correctly to resume normal controller operation.
The controller will not operate if the battery wires are
switched. Wire them correctly to resume normal controller
operation.
Fully protected against the load wiring short-circuit. Once the
load short (more than quadruple rate current), the load short
protection will start automatically. After 5 automatic load
reconnect attempts, the faults must be cleared by restarting
the controller.
