Rover Protections
Protection Behavior
When PV short 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 current exceeds the maximum load current rating of 21A,
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
and shut down when temperature exceeds 80.
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.
