Exterior and Interfaces

Introduction to Maximum Power Point Tracking Technology

• Maximum Power Point Tracking (MPPT) is an advanced charging technology that enables the solar panel to output more power by adjusting the electric module’s operating status.
• Due to the nonlinearity of solar arrays, there exists a maximum energy output point (maximum power point) on their curves. Unable to continuously lock onto this point to charge the battery, conventional controllers (employing switching and PWM charging technologies) can’t get most of the power from the solar panel. But a solar charge controller featuring MPPT technology can continuously track arrays’ maximum power point to get the maximum amount of power to charge the battery.
• Take a 12V system as an example. As the solar panel’s peak voltage (Vpp) is approximately 17V while the battery’s voltage is around 12V, when charging with a conventional charge controller, the solar panel’s voltage will stay at around 12V, failing to deliver the maximum power.
• However, the MPPT controller can overcome the problem by adjusting the solar panel’s input voltage and current in real-time, realizing a maximum input power.
• Compared with conventional PWM controllers, the MPPT controller can make the most of the solar panel’s max. power and therefore provide a larger charging current. Generally speaking, the latter can raise the energy utilization ratio by 15% to 20% in contrast with the former.
• Meanwhile, due to changing ambient temperature and illumination conditions, the max. power point varies frequently, and our MPPT controller can adjust parameter settings according to the environmental conditions in real-time, to always keep the system close to the max. operating point.
• The whole process is entirely automatic without the need for human intervention.

Charging Stage Introductions

As one of the charging stages, MPPT cannot be used alone. It is usually required to combine boost charge, floating charge, equalizing charge and other charging methods to complete the battery charging process. A complete charging process includes Quick charge, holding charge and floating charge.

The charging curve is shown below:

• a) Fast charging
  • At the fast charging stage, as the battery voltage has not reached the set value of full voltage (i.e. equalizing/ boost voltage) yet, the controller will perform MPPT charging on the battery with the maximum solar power.
  • When the battery voltage reaches the preset value, constant voltage charging will begin.
• b) Sustaining charging
  • When the battery voltage reaches the set value of holding voltage, the controller will perform constant voltage charging. This process will no longer include MPPT charging, and the charging current will gradually decrease with time.
  • Holding charge comes in two stages, i.e. equalizing charge and boost charge. The two stages are conducted without repetition, in which equalizing charge is started once every 30 days.

Boost charging

• By default, boost charging generally lasts for 2h, but users can adjust preset values of duration and boost voltage point according to the actual needs.
• When the duration reaches the set value, the system will then switch to floating charging.

Equalizing charging

• Warning: Risk of explosion!
  • In equalizing charging, an open lead-acid battery can produce explosive gas, therefore the battery chamber shall have good ventilation conditions.
• Note: risk of equipment damage!
  • Equalizing charging may raise the battery voltage to a level that may cause damage to sensitive DC loads. Check and make sure that allowable input voltages of all the loads in the system are greater than the set value for battery equalizing charging.
• Note: risk of equipment damage!
  • Overcharge or too much gas generated may damage battery plates and cause active material on the battery plates to scale off. Equalizing charging to an excessively high level or for too long a period may cause damage.
  • Read carefully the actual requirements of the battery deployed in the system.
  • Some types of batteries benefit from regular equalizing charging which can stir the electrolyte, balance the battery voltage and finish the electrochemical reaction.
  • Equalizing charging raises the battery voltage to a higher level than the standard supply voltage and gasifies the battery electrolyte.
  • If the controller then automatically steers the battery into equalizing charging, the charging duration is 120 mins (default).
  • To avoid too much generated gas or battery overheating, equalizing charging and boosting charging won’t repeat in one complete charging cycle.

Note:

1. When due to the installation environment or working loads, the system can’t continuously stabilize the battery voltage to a constant level, the controller will initiate a timing process, and 3 hours after the battery voltage reaches the set value, the system will automatically switch to equalizing charging.
2. If no calibration has been done to the controller clock, the controller will perform equalizing charging regularly according to its internal clock.

Floating charging

• When finishing the sustaining charging stage, the controller will switch to floating charging in which the controller lowers the battery voltage by diminishing the charging current and keeps the battery voltage at the set value of floating charging voltage.
• In the floating charging process, very light charging is carried out for the battery to maintain its full state.
• At this stage, the loads can access almost all the solar power.
• If the loads consume more power than the solar panel can provide, the controller will not be able to keep the battery voltage at the floating charging stage.
• When the battery voltage drops to the set value for returning to boost charging, the system will exit floating charging and reenter into fast charging.

PRODUCT INSTALLATION

Installation Precautions

• Be very careful when installing the battery. For open lead-acid batteries, wear a pair of goggles during installation, and in case of contact with battery acid, flush with water immediately.
• To prevent the battery from being short-circuited, no metal objects shall be placed near the battery.
• Acid gas may be generated during battery charging, thus make sure the ambient environment is well-ventilated.
• Keep the battery away from fire sparks, as the battery may produce flammable gas.
• When installing the battery outdoors, take sufficient measures to keep the battery from direct sunlight and rainwater intrusion.
• Loose connections or corroded wire may cause excessive heat generation which may further melt the wire’s insulation layer burn surrounding materials, and even cause a fire, therefore make sure all connections are tightened securely.
• Wires had better be fixed properly with ties, and when needs arise to move things, avoid wire swaying to keep connections from loosening.
• When connecting the system, the output terminal’s voltage may exceed the top limit for human safety. If an operation needs to be done, be sure to use insulation tools and keep your hands dry.
• The wiring terminals on the controller can be connected with a single battery or a pack of batteries. The following descriptions in this manual apply to systems employing either a single battery or a pack of batteries.
• Follow the safety advice given by the battery manufacturer.
• When selecting connection wires for the system, follow the criterion that the current density is not larger than 4A/mm2.
• Connect the controller’s earth terminal to the ground.

Wiring Specifications

Wiring and installation methods must comply with national and local electrical specifications. The wiring specifications of the battery and loads must be selected according to rated currents, see the following table for wiring specifications:

Models| Rated charging current| Rated discharging current| Battery wire diameter (mm 2 )| Load wire diameter (mm 2 )
---|---|---|---|---
ML2420| 20A| 20A| 5 mm2| 5 mm2

Installation and Wiring

Warning: risk of explosion! Never install the controller and an open battery in the same enclosed space! Nor shall the controller be installed in an enclosed space where battery gas may accumulate.

Warning: danger of high voltage! Photovoltaic arrays may produce a very high open-circuit voltage. Open the breaker or fuse before wiring, and be very careful during the wiring process.

Note: when installing the controller, make sure that enough air flows through the controller’s radiator, and leave at least 150 mm of space both above and below the controller so as to ensure natural convection for heat dissipation. If the controller is installed in an enclosed box, make sure the box delivers a reliable heat dissipation effect.

• Step 1: Choose the installation site Do not install the controller at a place that is subject to direct sunlight, high temperature or water intrusion, and make sure the ambient environment is well-ventilated.
• Step 2: first place the installation guide plate in a proper position, use a marking pen to mark the mounting points, then drill 4 mounting holes at the 4 marked points, and fit screws in.
• Step 3: fix the controller Aim the controller’s fixing holes at the screws fit in Step 2 and mount the controller on.
• Step 4: wire First remove the two screws on the controller, and then begin the wiring operation. To guarantee installation safety, we recommend the following wiring order; however, you can choose not to follow this order and no damage will be incurred to the controller.

1. Connecting to the external temperature sampling interface
2. Connecting communication cable
3. Connecting power cable
  *  **Warning:** risk of electric shock! We strongly recommend that fuses or breakers be connected at the photovoltaic array side, load side and battery side to avoid electric shock during wiring operation or faulty operations and make sure the fuses and breakers are in an open state before wiring.
  *  **Warning:** danger of high voltage! Photovoltaic arrays may produce a very high open-circuit voltage. Open the breaker or fuse before wiring, and be very careful during the wiring process.
  *  **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. First, connect the battery, then the load, and finally the solar panel. When wiring, follow the order of first “+” and then “-“.
4.  **Power on**
  * After connecting all power wires solidly and reliably, check again whether the wiring is correct and if the positive and negative poles are reversely connected. After confirming that no faults exist, first, close the fuse or breaker of the battery, then see whether the LED indicators light up and the LCD screen displays information. If the LCD screen fails to display information, open the fuse or breaker immediately and recheck if all connections are correctly done.
  * If the battery functions normally, connect the solar panel. If sunlight is intense enough, the controller’s charging indicator will light up or flash and begin to charge the battery.
  * After successfully connecting the battery and photovoltaic array, finally, close the fuse or breaker of the load, and then you can manually test whether the load can be normally turned on and off. For details, refer to information about load working modes and operations.

Warning: when the controller is in a normal charging state, disconnecting the battery will have some negative effect on the DC loads, and in extreme cases, the loads may get damaged.
Warning: within 10 minutes after the controller stops charging if the battery’s poles are reversely connected, internal components of the controller may get damaged.

Note:

1. The battery’s fuse or breaker shall be installed as close to the battery side as possible, and it’s recommended that the installation distance be not more than 150mm.
2. If no remote temperature sensor is connected to the controller, the battery temperature value will stay at 25 °C.
3. If an inverter is deployed in the system, directly connect the inverter to the battery, and do not connect it to the controller’s load terminals.

Load Mode Setting Interface

Load modes introduction: This controller has 5 load operating modes which will be described below.

present, the solar panel voltage is lower than the light control on voltage, and after a time delay, the controller will switch on the load; when sunlight emerges, the solar panel voltage will become higher than the light control off voltage, and after a time delay, the controller will switch off the load.
1~14| Light control + time control 1 to 14 hours| When no sunlight is present, the solar panel voltage is lower than the light control on voltage, and after a time delay, the controller will switch on the load. The load will be switched off after working for a preset period.
15| Manual mode| In this mode, the user can switch the load on or off with the keys, no matter whether it’s day or night. This mode is designed for some specially purposed loads and is also used in the debugging process.
16| Debugging mode| Used for system debugging. With light signals, the load is shut off; without light signals, the load is switched on. This mode enables a fast check of the correctness of system installation during installation debugging.
17| Normal on mode| The energized load keeps outputting, and this mode is suitable for loads that need a 24-hour power supply.

Load mode adjustment
Users can adjust the load mode as needed on their own, and the default mode is debugging mode (see “load modes introduction”). The method for adjusting load modes is as follows:

Manual load on/ off page

• Manual operation is effective only when the load mode is manual mode (15), and tap the Set key to switch on/ off the load under any main interface.

System Parameter Settings

• Under any interface other than load modes, press and hold the Set key to enter into the parameter setting interface.
• After entering into the setting interface, tap the Set key to switch the menu for setting, and tap the Up or Down key to increase or decrease the parameter value in the menu.
• Then tap the Return key to exit (without saving parameter setting), or press and hold the Set key to save setting and exit.
• Note: after the system voltage setting, the power supply has to be switched off and then on again, otherwise the system may work under an abnormal system voltage.
• The controller enables users to customize the parameters according to the actual conditions, but parameter setting must be done under the guidance of a professional person, or else faulty parameter settings may render the system unable to function normally.
• For details about parameter settings, see Table 3.

PRODUCT PROTECTION AND SYSTEM MAINTENANCE

Protections

• Waterproofing protection
  • Rating: IP32
• Input power limited protection
  • When the power of the solar panel is higher than the rated value, the controller will limit the power of the solar panel within the rated power range to prevent damage by over current, and the controller will enter the current-limiting charge.
• Battery reverse polarity protection
  • If the battery polarity is reversed, the system will not work but it will not burn out the controller.
• PV input end voltage is too high
  • If the voltage at the PV array input end is too high, the controller will automatically shut off the PV input.
• PV input end short circuit protection
  • If the voltage at the PV array input end is short-circuited, the controller will turn off charging; after the short circuit is removed, charging will automatically recover.
• PV input reverse polarity protection
  • When the polarity of the PV array is reversed, the controller will not be damaged, and normal operation will continue after the wiring error is corrected.
• Night reverse charging protection
  • Prevent battery discharge through the solar panel at night.
• TVS lightning protection
• Over-temperature protection
  • When the controller temperature exceeds the set value, it will decrease the charging power or halt charging.

See the following diagram:

System Maintenance

• To maintain the best long-term performance for the controller, it is recommended to conduct inspections twice a year.
• Make sure the airflow around the controller is not obstructed and remove any dirt or debris from the heat sink.
• Check if the insulation layers of all exposed wires are damaged due to sun exposure, friction with other objects nearby, dry rot, destruction of insects or rodents, etc. If so, it is necessary to repair or replace the wire.
• Verify if indicators are consistent with the device operations. Please note to take corrective actions for any malfunctions or error indications if necessary.
• Check all wiring terminals for corrosion, insulation damage, and signs of high temperature or burning/discolouration and tighten the terminal screws firmly.
• Check for dirt, insects nesting and corrosion and clean as required.
• If the lightning arrester has failed, replace it in time to protect the controller and other devices of the user from being damaged by lightning. operations. Please note to take corrective actions for any malfunctions or error indications if necessary.
