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 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 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.
Nominal 12 Volt Solar Module I-V curve and output power graph.
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.

MPPT—Four Charging Stages

Magicube series controller has a 4-stage battery charging algorithm for rapid, efficient, and safe battery charging.
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. 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
⑴ 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.
⑵ 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.
⑶ Double check whether battery voltage meets the voltage range of the Charge Controller.
⑷ 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.
⑸Batteries 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.
⑹ Only use insulated tools and avoid placing (any) metal objects near/close to batteries.
⑺ 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.
⑻ 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.
⑼ 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.
⑽ 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.
5.2 Mounting Location Requirements
Do not subject the PV charge controller to direct sunlight or any other heat sources. Protect the PV charcontroller from any dust, dirt and moisture. Mount it flat to a vertical wall. Must be a non-flammable material. Maintain a minimum clearance of 15 cm below and around the controller to ensure unhindered air circulation. Mount the PV charge controller not too far from the  batteries (for accurate voltage sensing least lessening).
Mark the position of the PV charge controller fastening holes on the wall, drill 4 holes and insert dowels, fasten the PV charge controller to the wall with the cable openings facing downwards.5.3 Fix the controller
Drill 4 mounting holes in the wall according to “installation position” and fix the four screws(M5) , then aim the controller’s fixing holes at the screws and mount the controller on.5.4 Connection
WARNING: The PV-module/array can produce open-circuit voltages in excess of 100 Vdc when exposed to sunlight. Pay highest attention to this fact.
WARNING: Risk of explosion! In case the battery’s positive and negative terminals or leads get ever in touch, i.e. short-circuited, a fire or explosion hazard might get triggered.
Always pay maximum when handling batteries and related circuits.
CAUTION: 1. When the controller is not connected with the external temperature sensor, the internal temperature of the battery is 25 ℃. 2.If a power inverter is used the system, directly  connect the inverter to the battery.
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.

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 ot 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).
5.5 Wiring Specifications
Wiring and installation methods must comply with national and local electrical code/specifications.
The wiring specifications of the PV-system battery must be selected according to rated currents. Please check following table for wiring specifications:

Model	Rated charging current	Rated discharging current	Solar wire diameter (mm2/AWG)	Battery wire diameter (mm2/AWG)	Load wire diameter (mm2/AWG)
MC2010	20A	20A	6/10	6/10	6/10
MC4010	40A	30A	10/8	10/8	6/9
MC6010/6015	60A	30A	16/5	16/5	6/9

The indicated cable/wire sizes are for reference only. If longer runs between the PV array and the controller or between the controller and the battery are required, than larger capacity  cables must be used to reduce voltage drop and improve system performance.
5.6 Grounding
Be aware that the negative terminals of controller are interconnected and therefore bear the same electrical potential. If any grounding is required, always do this on the negative  wires/terminals.

CAUTION: For common-negative system, such as motorhome, it is recommended to use a common-negative controller; but if in a common-negative system, some common-positive equipment is used, and the positive pole is grounded, the controller may get damaged.

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.

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