2,Overview
Win series solar controller is based on an advanced maximum power point tracking (MPPT) technology
developed, dedicated to the solar system, the controller conversion efficiency up to 98%.
The controller can rapidly track the maximum power point(MPP) of PV array to obtain the maximum
energy of the panel, especially in case of a clouded sky, when light intensity is changing continuously, an
ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers.

2.2 MPPT
MPPT profile
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could
detect the real-time power of the solar Modulel and the maximum point of the I-V curve that make the
highest battery charging efficiency.
Current Boost
Under most conditions, MPPT technology will "boost" the solar charge current.
MPPT Charging:Power Into the controller (Pmax)=Power out of the controller (Pout)
Iin x Vmp= Iout x Vout
* Assuming 100% efficiency. Actually, the losses in wiring and conversion exist.
If the solar module's maximum power voltage (Vmp) is greater than the battery voltage, it follows that the
battery current must be proportionally greater than the solar input current so that input and output power are
balanced. The greater the difference between the Vmp and battery voltage, the greater the current boost.
Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the
battery as described in the next section.
High Voltage Strings and Grid-Tie Modules
Another benefit of MPPT technology is the ability to charge batteries with solar arrays of higher nominal
voltages. For example, a 12 Volt battery bank may be charged with a 12-, 24-, 36-, or 48-Volt nominal off-grid
solar array. Grid-tie solar modules may also be used as long as the solar array open circuit voltage (Voc) rating
will not exceed the maximum input voltage rating at worst-case (coldest) module temperature. The solar module
documentation should provide Voc vs. temperature data.
Higher solar input voltage results in lower solar input current for a given input power. High voltage solar input
strings allow for smaller gauge solar wiring. This is especially helpful and economical for systems with long wiring
runs between the controller and the solar array.

An Advantage Over Traditional Controllers
Traditional controllers connect the solar module directly to the battery when recharging. This requires
that the solar module operate in a voltage range that is usually below the module's Vmp. In a 12 Volt
system for example, the battery voltage may range from 10.8-15 Vdc,but the module's Vmp is typically
around 16 or 17V.
Because traditional controllers do not always operate at the Vmp of the solar array, energy is wasted that
could otherwise be used to charge the battery and power system loads. The greater the difference
between battery voltage and the Vmp of the module, the more energy is wasted.

Contrast with the traditional PWM controller, MPPT controller could play a maximum power of the solar
panel so that a larger charging current could be supplied. Generally speaking, the MPPT controller's
energy utilization efficiency is 15%~20% higher than PWM controller.
Conditions That Limit the Effectiveness of MPPT
The Vmp of a solar module decreases as the temperature of the module increases. In very hot weather,
the Vmp may be close or even less than battery voltage. In this situation, there will be very little or no
MPPT gain compared to traditional controllers. However, systems with modules of higher nominal voltage
than the battery bank will always have an array Vmp greater than battery voltage. Additionally, the savings
in wiring due to reduced solar current make MPPT worthwhile even in hot climates.

MPPT Charge
In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is
used to recharge the battery.
Boost Charge
When the battery has recharged to the Boost voltage setpoint, constant-voltage regulation is used to
prevent heating and excessive battery gassing. The Boost stage remains 120 minutes and then goes to
Float Charge. Every time when the controller is powered on, if it detects neither over discharged nor
overvoltage, the charging will enter into boost charging stage.
Float Charge
After the Boost voltage stage, the controller will reduce the battery voltage to Float voltage setpoint.
When the battery is fully recharged, there will be no more chemical reactions and all the charge current
transmits into heat and gas at this time. Then the controller reduces the voltage to the floating stage,
charging with a smaller voltage and current. It will reduce the temperature of battery and prevent the
gassing, also charging the battery slightly at the same time. The purpose of Float stage is to offset the
power consumption caused by self consumption and small loads in the whole system, while maintaining
full battery storage capacity.
In Float stage, loads can continue to draw power from the battery. In the event that the system load(s)
exceed the solar charge current, the controller will no longer be able to maintain the battery at the Float
setpoint. Should the battery voltage remains below the boost reconnect charging voltage, the controller
will exit Float stage and return to Bulk charging.
Equalization Charge
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. If it detects that the battery
is being over discharged, the solar controller will automatically turn the battery to equalization charging
stage, and the equalization charging will be 120mins. Equalizing charge and boost charge are not carried
out constantly in a full charge process to avoid too much gas precipitation or overheating of battery.

5,Installation
Please read all instructions and precautions in the manual before installing.
5.1 Installation Notes
⑴The solar charge controller may only be used in PV systems in accordance with this user manual and
the specifications of other modules manufacturers. No energy source other than a solar generator may be
connected to the solar charge controller.
⑵Before wiring installation and adjustment of controller, Always disconnect the solar modules and
insurance or circuit breaker of battery terminal.
⑶Only to comply with the range of the battery charge controller.
⑷Batteries store a large amount of energy, never short circuit a battery under all circumstances. We
strongly recommend connecting a fuse directly to the battery to avoid any short circuit at the battery
wiring.
⑸
Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame. Make sure
that the battery room is ventilated.
⑹Uses insulated tools and avoid placing metal objects near the batteries. ⑺Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash
and clean any contact with battery acid.
⑻
Avoid touching or short circuiting wires or terminals. Be aware that the voltages on special terminals or
wires can be as much as twice the battery voltage. Use isolated tools, stand on dry ground, and keep your
hands dry.
⑼
Prevent water from entering the internal controller, outdoor installation should avoid direct sunlight
and rain penetration.
⑽After installation check that all connections are tight line, avoid heat accumulation caused by virtual
access danger.
5.2 Mounting Location Requirements
Do not subject the solar charge controller to direct sunshine or other sources of heat. Protect the solar
charge controller from dir t and moisture. Mount upright on the wall on a non-flammable substrate.
Maintain a minimum clearance of 15cm below and around the device to ensure unhindered air circulation.
Mount the solar charge controller as close as possible to the batteries.
Mark the position of the solar charge controller fastening holes on the wall, drill 4 holes and insert
dowels, fasten the solar charge controller to the wall with the cable openings facing downwards.

5.3 Wiring Specifications
Wiring and installation methods must comply with national and local electrical specifications.
The wiring specifications of the solar, battery must be selected according to rated currents, and see the
following table for wiring specifications:
Rat ed char ging c urren t
20A 5 /10 5/1 0
!
The wire size is only for reference. If there is a long distance between the PV array and the
controller or between the controller and the battery, larger wires can be used to reduce the voltage
drop and improve performance.
5.4 Connection
We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the
battery wiring. Solar PV modules create current whenever light strikes them. The current created varies
with the light intensity, but even in the case of low levels of light, full voltage is given by the modules. So,
protect the solar modules from incident light during installation. Never touch uninsulated cable ends, use
only insulated tools, and make sure that the wire diameter is in accordance with the expected currents of
solar charge controller. Connections must always be made in the sequence described below.
WARNING: Risk of electric shock! Exercise caution when handing solar wiring. The solar
PV array can produce open-circuit voltages in excess of 100V when in sunlight. Pay more
attention to it.
WARNING: Risk of explosion! Once the battery's positive and negative terminals or leads
that connect to the two terminals get short-circuited, a fire or explosion will occur. Always
be careful in operation.
1st step: Connect the battery
Connect the battery connection cable with the correct polarity to the middle pair of terminals on the
solar charge controller (with the battery symbol). If the system is 12V, please make sure that the battery
voltage is within 5V~15.5V, else if the system is 24V, the battery voltage should between 20V~31V.
2nd step: Connect the solar module
Ensure that the solar module is protected from incident light. Ensure that the solar module does not
exceed the maximum permissible input current. Connect the solar module connection cable to the correct
polarity of the left pair of terminals on the solar charge controller (with the solar module symbol).
3th step: Final work
Tighten all cables connected to the controller and remove all the debris around the controller (leaving a
space of approx. 15 cm).
5.5 Grounding
Be aware that the negative terminals of controller are connected together and therefore have the same
electrical potential. If any grounding is required, always do this on the negative wires.
For common-negative system, such as motorhome, it is recommended to use a commonnegative controller; but if in the common-negative system, some common-positive
equipment are used, and the positive electrode is grounded, the controller may be
damaged.
