other.

Recycle battery when it is replaced.

Over-charging and excessive gas precipitation may damage the battery plates and

activate material shedding on them. Too high of an equalizing charge or too long

of one may cause damage. Please carefully review the specific requirements of

the battery used in the system.

Equalization is carried out only for non-sealed / vented/ flooded / wet cell lead acid

batteries.

Do NOT equalize sealed / VRLA type AGM / Gel cell batteries UNLESS permitted

by battery manufacturer.

WARNING: Connect battery terminals to the charge controller BEFORE connecting

the solar panel(s) to the charge controller. NEVER connect solar panels to charge

controller until the battery is connected.

WARNING: Do NOT connect any inverters or battery charger into the load terminal

of the charge controller.

WARNING: Once equalization is active in the battery charging, it will not exit this

stage unless there is adequate charging current from the solar panel. There should

be NO load on the batteries when in equalization charging stage.

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.

The Rover’s charging process has been optimized for long battery life and improved

system performance. The comprehensive self-diagnostics and electronic protection

functions can prevent damage from installation mistakes or system faults.

Key Features

Automatically detect 12V or 24V DC system voltages

Innovative MPPT technology with high tracking efficiency up to 99% and peak

conversion efficiency of 97%

Deep cycle Sealed, Gel, and Flooded battery option ready

Electronic protection: Overcharging, over-discharging, overload, and short circuit

Reverse protection: Any combination of solar module and battery, without causing

damage to any component

Customizable charging voltages

MPPT Technology

The MPPT Charge Controller utilizes Maximum Power Point Tracking technology to

extract maximum power from the solar module(s). The tracking algorithm is fully

automatic and does not require user adjustment. MPPT technology will track the array’s

maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that the

maximum power is harvested from the array throughout the course of the day.

Current Boost

In many cases, the MPPT charge controller will “boost” up the current in the solar system.

The current does not come out of thin air. Instead, the power generated in the solarpanels

is the same power that is transmitted into the battery bank. Power is the product of Voltage

(V) x Amperage (A).

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.

The voltage generated at the solar module needs to be stepped down to a rate that could

charge the battery in a stable fashion by which the amperage is boosted accordingly to

the drop. It is entirely possible to have a solar module generate 8 amps going into the

charge controller and likewise have the charge controller send 10 amps to the battery

bank. This is the essence of the MPPT charge controllers and their advantage over

traditional charge controllers. In traditional charge controllers, that stepped down voltage

amount is wasted because the controller algorithm can only dissipate it as heat. The

following demonstrates a graphical point regarding the output of MPPT technology.

Limiting Effectiveness

Temperature is a huge enemy of solar modules. As the environmental temperature

increases, the operating voltage (Vmp) is reduced and limits the power generation of the

solar module. Despite the effectiveness of MPPT technology, the charging algorithm will

possibly not have much to work with and therefore there is an inevitable decrease in

performance. In this scenario, it would be preferred to have modules with higher nominal

voltage, so that despite the drop in performance of the panel, the battery is still receiving

a current boost because of the proportional drop in module voltage.

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*.

Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available

solar power to recharge the battery and is equivalent to constant current. In this stage the

battery voltage has not yet reached constant voltage (Equalize or Boost), the controller

operates in constant current mode, delivering its maximum current to the batteries (MPPT

Charging)

Constant Charging: When the battery reaches the constant voltage set point, the

controller will start to operate in constant charging mode, where it is no longer MPPT

charging. The current will drop gradually. This has two stages, equalize and boost and

they are not carried out constantly in a full charge process to avoid too much gas

precipitation or overheating of the battery.

Boost Charge: Boost stage maintains a charge for 2 hours by default. The user

can adjust the constant time and preset value of boost per their demand.

Float Charge: After the constant voltage stage, the controller will reduce the battery

voltage to a float voltage set point. Once the battery is fully charged, there will be no more

chemical reactions and all the charge current would turn into heat or gas. Because of this,

the charge controller will reduce the voltage charge to smaller quantity, while lightly

charging the battery. 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 28 days of the month. It is intentional overcharging

of the battery for a controlled period of time. Certain types of batteries benefit from

periodic equalizing charge, which can stir the electrolyte, balance battery voltage and

complete chemical reaction. Equalizing charge increases the battery voltage, higher

than the standard complement voltage, which gasifies the battery electrolyte.

WARNING: Once equalization is active in the battery charging, it will not exit this

stage unless there is adequate charging current from the solar panel. There should

be NO load on the batteries when in equalization charging stage.

WARNING: Over-charging and excessive gas precipitation may damage the battery

plates and activate material shedding on them. Too high of equalizing charge or for

too long may cause damage. Please carefully review the specific requirements of

the battery used in the system.

WARNING: Equalization may increase battery voltage to a level damaging to

sensitive DC loads. Ensure that all load allowable input voltages are greater than

the equalizing charging set point voltage.

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.

USB to RS-232 Converter Cable: This PC communication cable is

needed for remote monitoring using an optional PC software.

Through the software, users could customize their charge

parameters and other settings. Download the PC software through

Renogy’s website under the “Downloads” section.

NOTE: PC Communication requires the USB be connected at all times.

Wireless capability not available.

WARNING: Do NOT use a PC Ethernet cable. This can and will cause

permanent damage to a computer.
