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.
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 VRLA type AGM / Gel / Lithium cell batteries UNLESS permitted by
battery manufacturer.
Carefully read battery manuals before operation.
Do
NOT
let the positive (+) and negative (-) terminals of the battery touch each other.
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.
Do NOT connect any inverters or battery charger into the load terminal of
the charge controller.
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
Recycle battery when it is replaced.

General Information
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.
The Rover Series charge controllers are intelligent controllers 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
dis
connect 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.
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 solar panels 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.
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.

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) .
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,
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.

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.
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.
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.
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.
WARNING
WARNING
WARNING
The Rover MPPT charge controller has a reactivation feature to awaken a sleeping lithium
battery. The protection circuit of lithium battery will typically turn the battery off and make it
unusable if over-discharged. This can happen when storing a lithium battery pack in a
discharged state for any length of time as self-discharge would gradually deplete the remaining
charge. Without the wake-up feature to reactivate and recharge batteries, these batteries would
become unserviceable and the packs would be discarded. The Rover will apply a small charge
current to activate the protection circuit and if a correct cell voltage can be reached, it starts a
normal charge.

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 c
ontroller 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.

When selecting User, the battery type is to be self-customized, and in this case, the default
system voltage parameters are consistent with those of the sealed lead-acid battery. When
modifying battery charging and discharging parameters, the following rule must be followed:
PV Power – Conversion Efficiency Curves
Temp 25℃
2. 24 Volt System Conversion Efficiency1.12 Volt System Conversion Efficiency
Illumination Intensity: 1000W/ m

3. 48 Volt System Conversion Efficiency
Default charging parameters in LI mode are programmed for 12.8V LFP battery. Before
using Rover to charge other lithium battery, set the charging parameters according to the
suggestions from battery manufacturer.
The above parameters are based on 12V system settings. Parameters are multiplied by 2
for 24V systems, multiplied by 3 for 36V systems, and multiplied by 4 for 48V systems.
For Equalization Interval Setting under USER mode, 0 Day refers to turning off the
equalization function.
