Rover Protections

Protection Behavior

When PV shot circuit occurs, the controller will stop charging.

Clear it to resume normal operation.

If the PV voltage is larger than maximum input open voltage

100VDC, PV will remain disconnected until the voltage drops

below 100VDC.

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 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 the 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.
