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 Module 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 ChargingPower 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 offgrid 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 the 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 PWM controllers connect the solar module directly to the battery when recharging. This requires that the solar module operates 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.

In 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 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 to or even less than the 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 the battery voltage. Additionally, the savings in wiring due to the reduced solar current make MPPT worthwhile even in hot climates.

2.3 MPPT–Four Charging Stages

Magicube series controller has a 4-stage battery charging algorithm for rapid, efficient, and safe battery

charging.

TIME

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. Whenever the controller is powered on, if it detects neither over discharged nor overvoltage, the charging will enter into the 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 the 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 the Float stage, loads can continue to draw power from the battery. If 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 the Float stage and return to Bulk charging.

Equalize 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 the 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 the

battery.

WARNING: Risk of explosion!

Equalizing flooded battery can produce explosive gases, so well ventilation of battery box is

necessary.

CAUTION: Please read all instructions and precautions in the manual before proceeding with the installation! It is recommended to remove the protective film cover from the LCD screen before operation. 5.1 Installation Notes This charge controller must only be used in PV systems by requirements given in this user manual and the specifications of other system components provided by their manufacturers. No energy source other than a PV generator may be connected to the PV charge controller referred to herein. PV-modules must always be disconnected prior to the installation and adjustments of the charge controller; Make sure the circuit breaker, fuse or disconnects of the battery terminal are turned off. Double check whether battery voltage meets the voltage range of the Charge Controller. Batteries store a large amount of energy, never short circuit a battery under any circumstances. We strongly recommend connecting a protection fuse directly to the battery terminal for protection in case of short circuiting the battery. Batteries can produce flammable gases. Avoid provoking any sparks, using fire or any exposed flame close to any batteries, ever. Make sure that the battery room is well ventilated to disperse any gases. Only use insulated tools and avoid placing (any) metal objects near/close to batteries. Be extremely cautious when working with batteries. Wear eye protection by all means. Have fresh water available to immediately wash and clean any contact with battery acid. Get immediate medical aid in case of any hazard that may occur. Never install/handle with batteries alone. Avoid touching or short-circuiting wires or terminals. Be aware that voltages on given system components, terminals or wires can be a multiple of battery voltage. Only use insulated tools, stand on dry ground, and keep your hands always dry and protected by proper (approved) electrician gloves when working on PV-Systems. Prevent any water, ever, from penetrating the controller, outdoor installation must avoid any direct sunlight and penetration of any water (e.g. rain) and humidity. After installation make sure that all connections are properly tightened, and eliminate any electrical loose connections to eliminate by all means any hot electrical connection spots.

We strongly recommend connecting a fuse directly to the battery terminal to protect from any short circuit in the battery circuit. PV-modules generate current whenever light shines on them. The generated current is directly proportional to the light intensity. Even low levels of light, will deliver the PV-Modules no load, full voltage. It is thus utterly advisable to protect PV-modules from any incident light during installation; Never touch uninsulated cables (ends), only use electric insulated tools, and make sure that the wire cross section is adequate for the PV module operating currents. Connections must always be conducted in the sequence as described below.

RS485 communication
interface

1st step: Connect accessories (1)Connect the remote temperature sensor cable Connect the remote temperature sensor cable to the interface and place the other end close to the battery. (2)Connect the accessories for RS485 or IoT communication. 2nd step: Connect loads Connect the load cable with the correct polarity of the right-hand side pair of terminals on the solar charge controller (with the lamp symbol). To avoid the presence of any tension on the cable/wires, please connect these first to the load before connecting them to the charge controller. 3rd step: Connect the battery Connect the battery cables observing the correct polarity to the center pair of terminals (make sure you identify the battery marking/symbol on the controller casing!) of the PV charge controller. Pay greatest attention to polarity. Never, ever invert the plus+ and minus- poles).
1) Should your system be nominal 12 Vdc, make sure the battery voltage is between the 5 and 15.0 Vdc voltage range;
2) for 24 Vdc nominal voltage, the battery voltage should be within the 20 to 31 Vdc range; 3) for 36 Vdc nominal voltage, the battery voltage should be within the 31 to 42 Vdc range; 4) for 48 Vdc nominal voltage, the battery voltage should be within the 42 to 62 Vdc range. 5) Voltages are identifiable when the controller is set to a lithium battery. If the polarity is correct, the LCD on the controller will begin to display those. 4th step: Connect the solar module When connecting the PV-Module make sure to cover it from incident sun light. Double check the PVModule will not exceed the maximum permissible input current of the Charge Controller (please refer to the section Technical Data). 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). 5th step: Final work Tighten all cables connected to the controller and remove all the remains around the controller (leaving a void of minimum 15 cm).

Street Lamp Function When the load is set to Dusk to Dawn or Evening mode, the Day/Night threshold voltage and the Day/Night delay time can be set by IoT, RS485 or bluetooth APP, and the load can be turned on or off by the test function during the day charging process. 2.1 Day/Night threshold voltage The controller recognizes day and night based on the solar array open circuit voltage. This day/night threshold voltage can be modified according to local light conditions and the solar array used. Day/Night threshold setting range: 3.0~10.0/6.0~20.0/9.0~30.0/12.0~40.0V(Default: 8/16/24/32V) 2.2 Day/Night delay time In the evening, when the solar array open circuit voltage reaches the setting day/night detect voltage, you can adjust the day/night delay time to make the load turn on a little bit later. Day/Night delay time setting range: 0~30min(Default: 0min) 2.3 Test Function When the controller is working in Dusk to Dawn or Evening mode, press the MENU key for 3s to turn on the load. Press the MENU key again or the load turns off automatically after 1 minute. If the controller is operating in always on mode, the test function does not work.
3.User-defind Mode If the load mode is selected “USE”, then you can switch on and off the load output manually by pressing MENU shortly. The default switching state of the load in manual mode can be changed by IoT, RS485 or bluetooth APP. At the same time, the output to the load can be turned on or off.
1.If the controller turns off the load due to low voltage protectionovercurrent protectionshort-circuit protection or over temperature protection, the load will turn on automatically when the controller recovers from protection state. 2.Please note: Pushing the MENU button can still activate the function of the key, even during of the above four kinds protection states.
7, Troubleshooting, Protections and maintenance
7.1Trouble shooting

Faults

Reason Short Circuit Over Current Battery voltage is too low

Troubleshooting
Clear short circuit fault Restart the controller or press the key to restore the load output Reduce electrical equipment; Restart the controller or press the key to clear the fault load and restore the output
Load will be reconnected when battery is recharged.

Battery voltage is too high

Check if other sources overcharge the battery or battery parameter is set correctly. If not, controller is damaged.

Battery voltage is abnormal

Charge or discharge the battery so that the battery voltage is within the normal operating range(5.0~15.0V

at start-up

or 20~31V or 31~42 or 40~62V).

Over temperature

After the temperature decreases, the controller will work normally.

7.2 Protection

Protection PV Over Current PV Short Circuit

Description
The controller will limit charging power to the rated level. Over-sized PV array will not be able to operate at the maximum power point.
When PV short circuit occurs, the controller will stop charging. Remove it to resume normal operation. When the PV doesn’t charge, the controller will not be damaged if short-circuit just happened in the PV array. Warning: It is forbidden to short-circuit the PV array during charging. Otherwise, the controller may be damaged.

PV Reverse Polarity

Fully protection against PV reverse polarity, no damage to the controller. Correct the connection to resume normal operation.

Battery Reverse Polarity

Fully protection against battery reverse polarity, no damage to the controller. Correct the connection to resume normal operation.

Battery Over voltage

Should there are other energy sources to charge the battery, when the battery voltage exceeds 15.8 / 31.3 / 46.8 / 62.3V(Overcharge protection voltage of lithium battery equals target voltage plus 0.2V), the controller will stop charging to protect the battery from overcharging damage.

Battery Over discharge

When the battery voltage drops to the low voltage disconnect setting, the controller will stop discharging to protect the battery from over discharging

Load Over Current Protection
Load Short Circuit Protection
Over Temperature Protection
Damaged Remote Temperature Sensor

IIf the load current exceeds the maximum load current rating 1.25 times, the controller will automatically cut off the output. If the load reconnects the output automatically 10 times, it needs to be cleared by pressing the test key, restarting the controller or switching from Night to the Day. When the load output of the controller is short circuited, the controller will automatically cut off the output. If the load reconnects the output automatically 10 times, it needs to be cleared by pressing the test key, restarting the controller or switching from Night to the Day. The controller detects the internal temperature through internal sensor, when the temperature exceeds the setting value, the charging current will decrease. The controller stops working when the internal temperature exceeds 75 and resumes work when the internal temperature is below 65.
When the external temperature sensor is damaged or not connected, the controller will charge at 25 by default to prevent overcharge from damaging the battery.

7.3 Maintenance For best system performance, the following inspections and maintenance tasks are recommended to be carried out for at least two times a year.
Make sure no block on air-flow around the controller. Clear up any dirt and fragments on radiator.

Check all the naked wires to make sure insulation is not damaged. Repair or replace some wires if necessary.

Tighten all terminal screws to the indicated torque; Inspect for loose, broken, or burnt cable/wire connections.

Check and confirm that LCD is consistent with required. Pay attention to any troubleshooting or error indication. Take corrective action if necessary.

Make sure all system components are effectively and tightly connected to ground.

Check all terminals for any corrosion signs, damaged insulation, increased temperature .

Check for any dirt, nesting insects and any corrosion signs. Implement corrections actions as early as possible.

WARNINGRisk of electric shock! Make sure that all the power is turned off before above operations, and then follow the corresponding inspections and operations.
