Important Safety Instructions Please save these instructions. This manual contains important safety, installation, and operating instructions for the charge controller. The following symbols are used throughout the manual to indicate potentially dangerous conditions or important safety information. WARNING CAUTION NOTE Indicates a potentially dangerous condition.
Battery Safety Use only sealed lead-acid, flooded, gel or lithium batteries which must be deep cycle. Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases. Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid. Carefully read battery manuals before operation. Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.

General Information The Rover Series charge controllers are suitable for various off-grid solar applications. It protects the battery from being over-charged by the solar modules and over-discharged by the loads. The controller features a smart tracking algorithm that maximizes the energy from the solar PV module (s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.
Therefore, assuming 100% efficiency: Power In = Power Out Volts In * Amps In = Volts out * Amps out Although MPPT controllers are not 100% efficient, they are very close at about 92-95% efficient. Therefore, when the user has a solar system whose Vmp is greater than the battery bank voltage, then that potential difference is proportional to the current boost.
Four Charging Stages The Rover MPPT charge controller has a 4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization*. Battery Voltage A Bulk Charging B Constant Charging C Float Charging Equalize Boost Bu lk Boost Float Recharge Time Battery Current Duration Time:2h (Range:10~180min) Cumulative Time:3h Max Current Time Bulk Charge: This algorithm is used for day to day charging.
The purpose for this is to offset the power consumption while maintaining a full battery storage capacity. In the event that a load drawn from the battery exceeds the charge current, the controller will no longer be able to maintain the battery to a Float set point and the controller will end the float charge stage and refer back to bulk charging. Equalization: Is carried out every 30 days of the month. It is intentional overcharging of the battery for a controlled period of time.
Additional Components Additional components included in the package: Remote Temperature Sensor: This sensor measures the temperature at the battery and uses this data for very accurate temperature compensation. Accurate temperature compensation is important in ensuring proper battery charging regardless of the temperature. Controller Paralleling Cable: This communication cable is needed to parallel two or more Rover 100A charge controllers. Paralleling 100A Rovers allows for higher wattage systems.

Installation Recommended tools to have before installation: Screwdriver WARNING Multi-Meter Connect battery terminal wires to the charge controller FIRST then connect the solar panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery. INVERTER BATTERY CHARGER HIGH AMP DRAWING DEVICE CAUTION CAUTION Do not over tighten the screw terminals. This could potentially break the piece that holds the wire to the charge controller.

7. Paralleling Function (Optional) Parallel Port NOTE 13 Use the provided paralleling cable to combine multiple Rover 100A Charge Controllers. Connect the cable into the port labeled Parallel Operation on each Rover 100A. Using this function will allow the Rover to act as one large charge controller (Example above 300A).
Mounting Recommendations WARNING NEVER INSTALL THE CONTROLLER IN A SEALED ENCLOSURE WITH FLOODED BATTERIES. GAS CAN ACCUMULATE AND THERE IS A RISK OF EXPLOSION. 1. Choose Mounting Location — place the controller on a vertical surface protected from direct sunlight, high temperatures, and water. Make sure there is good ventilation. 2. Check for Clearance — verify that there is sufficient room to run wires, as well as clearance above and below the controller for ventilation.
Operation Rover is very simple to use. Simply connect the batteries, and the controller will automatically determine the battery voltage. The controller comes equipped with an LCD screen and 4 buttons to maneuver though the menus.

Protections Protection 25 Behavior PV Array Short Circuit When PV shot circuit occurs, the controller will stop charging. Clear it to resume normal operation PV Overvoltage If the PV voltage is larger than maximum input open voltage 150VDC, PV will remain disconnected until the voltage drops below 150VDC. PV Overcurrent 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.
System StatusTroubleshooting PV indicator Off during daylight BATT Indicator Troubleshoot Ensure that the PV wires are correctly and tightly secured inside the charge controller PV terminals. Use a multi-meter to make sure the poles are correctly connected to the charge controller. Troubleshoot White Slow Flashing Disconnect loads, if any, and let the PV modules charge the battery bank. Use a multi-meter to frequently check on any change in battery voltage to see if condition improves.
