  Warning : Serial solar and battery fuses or DC circuit breakers are required in the system. These guards are located outside the MPPT controller.
  Warning: Installation must comply with electrical code requirements. Select suitable specifications for circuit breakers and fuses based on application requirements.

Installation Steps

Check the controller for shipping damage. Do not install directly on flammable surfaces as the radiator may become hot under certain operating conditions.

To ensure room for airflow, allow at least 30 cm (12 in) above and below the controller and 50 mm (2 in) on both sides. Do not install in a container where accumulator gas may accumulate.

Note: There should be enough space between the top and bottom for the fan to dissipate heat.

Step 1: Check Controller Parameter Limits
Check that the maximum temperature compensated solar array open circuit voltage (Voc) and load current do not exceed the ratings of the MPPT version being installed. Multiple controllers can be installed in parallel on the same battery pack for greater total charge current. In this type of system, each MPPT must have its own solar panel. The load terminals of multiple controllers can be connected together only if the total load does not exceed the rated current of a single controller.
Step 2: Connect the input and output power cables
 
Follow the wiring sequence ①, ②, ③ to wire and tighten the screws.
Step 4: Make mounting holes in the mounting wall

Measure and mark the distance on the wall, drill 4 holes of 6mm diameter and fill the 4 holes with plastic expansion pellets

Step 5: Mount the Controller to the Wall
Align the fixing holes of the controller with the mounting holes made in step 4, use M4 self-tapping screws to fix the controller on the installation wall and tighten the screws.

Step 6: Power on and run

Check to make sure the solar panel and battery are in normal condition, double check that the
input and output cables are connected correctly, then power up the battery first, then the solar panel, the controller will run automatically.
Note: Before connecting the battery, the open circuit voltage of the battery must be measured . It must exceed 10 volts to activate the controller. If the system voltage is set to auto detect, battery voltages over 18V will be detected as a nominal 24V battery and the device will charge the 24V battery. 12/24/48V only auto-selected at power-up.
Warning : Potential for damage Disconnect the battery from the MPPT as soon as possible after the solar input is disconnected. If the battery is removed during MPPT charging, there is a low chance of damage to the controller.
Note: To prevent damage, power must be turned on in the following order; power off must be reversed from power on

Start steps ：step 1： Turn on the circuit breaker connected to the battery first, make sure that the controller is connected to the battery (the controller LCD will display the content), and set the battery type;
step 2： If a DC output is required to control the load， Please set the output control mode first， Then open the DC output “breaker”；
step 3： Connect a circuit breaker that turns on the PV input of the solar panel ，If the voltage of the PV input is within the charging operating range of the controller, the controller will enter the charging state；
shutdown process ： Turn off the “circuit breaker” in turn ③,②,①

Working principle and operation guide

The maximum power point tracking technology

Power is equal to the product of voltage and current. The following equation holds *:

1. Input power of MPPT = output power of MPPT
2. Input voltage × input current = output voltage × output current

Assumes 100% conversion efficiency, ignoring line losses and energy conversion losses.
If the Vmp of the solar panel array is greater than the battery voltage, the battery current must be proportionally greater than the solar input current to balance the input and output power. The greater the difference between the maximum photovoltaic input voltage and the battery voltage,  the greater the difference between the input and output currents.

For a given input power, a higher input voltage of a solar module array results in a lower solar input current. An array of high voltage solar input modules allows the use of smaller gauge solar wiring. This is very beneficial for systems that require long wiring between the solar module array and the MPPT.

Compared to the traditional controller, the principle of it is to connect the solar module directly to the battery when charging. This requires the solar module to operate in a voltage range lower than the module Vmp. For example, in a 12V system, the battery voltage may be between 10-15- VDC, but the Vmp of the module is usually around 17V. The figure below shows a typical current vs. voltage output curve for a nominal 12V charging system.

Charge status and parameters

The controller charges the lead-acid battery

The MPPT controller has a 4-stage battery charging algorithm for fast, efficient and safe charging
of lead-acid batteries.

1. – CC State (Constant Current Charging): Fast Charging Phase – FAST
2. – CV state (constant voltage charging): regulated charging phase – KEEP
3. – CF Status (Float Charging): Prevents the battery from being overcharged for a long time. And make up for the loss of self-discharge. -FULL
4. – Boost charging: activate battery chemistry, desulphurization effect

The controller charges the lithium-ion battery

The MPPT controller will charge according to the specifications of the lithium-ion battery, mainly in two stages. In the first stage, when the battery voltage is lower than the saturation voltage, it will rapidly charge according to the maximum power point that is tracked; in the second stage, when the battery voltage is equal to the saturation voltage, it will charge at a constant voltage, and the charging current will gradually decrease to 0.

Charging parameter settings

Note : These settings are general guidelines for user operation. MPPT can be set to meet various charging parameters. Check with the battery manufacturer for  the best battery charging settings.

Load Control

The main purpose of the load control function is to disconnect the system load when the battery is discharged to a low voltage state and reconnect the system load when the battery is charged back to a certain level. System loads can be lamps, DC appliances, or other electronic equipment. The total current of all loads must not
exceed the MPPT maximum load rating.
Reminder : Risk of Equipment Damage
Do not connect any AC inverter to the load terminals of the MPPT. The load control circuit may be damaged. The inverter should be connected to the battery. If any other load may sometimes exceed the maximum voltage or current limit, the device should be connected directly to the battery or battery pack. Brief description of load control:

Do not connect multiple MPPT load outputs in parallel to power supply dc loads that consume more than 30A current, depending on the MPPT model used.

Be careful when connecting loads with specific polarities to controller load terminals. Reverse polarity connections may damage the load. Be sure to check the load connection carefully before powering on.

The load output voltage of the controller is the same as that of the battery string. For example, when the battery voltage is 25.2V, the load output voltage is also 25.2V.
When the load output current is lower than the rated load current, the system provides stable power to the load.

When the load output current exceeds the preset load current and lasts for 5 minutes in the range of 100% to 120%, the load output is shut down and switches to the normal off mode.

When the load output current is detected to exceed 120% of the rated load current, the load output will be shut down immediately and switch to the normal off mode.
****Attention: When the Load switches to normal off mode, in order to restart the Load, the user needs to reset the Load to “ON” mode ON the controller or reset the Load mode through the mobile APP, upper computer, and meter header.

Load Control Mode:

1.  Normal on/Normal Off mode: The load output state is on or off.
2. Optical control mode: The load output is turned on or off according to whether there is light (input voltage limit). Refer to the following diagram for the working mechanism.
3. Dual-period timing control mode: The load switch of two different periods is controlled according to two timers. Refer to the following diagram for the working mechanism.
4. Fixed time light control mode: according to whether there is light (input voltage limit), the load output is controlled to turn on or off in hourly units.

Light (PV) Control Mode

Dual-timer Interval Control Mode

Time & Light (PV) Control Mode

Attention : Only the normal ON/normal OFF mode can be set on the controller panel. Other modes need to beset through other optional accessories.
Attention: Please refer to Section 4.5 for setting the normally on/OFF mode

LED Indicators

Green: Indicates charging status. When flashing fast, it means it is in fast charging state (CC mode); when flashing slowly, it means it is in constant voltage charging state (constant voltage charging CV); when it is always on, it means it is in floating charging state (CF) or standby mode.

Red: If a fault occurs, the indicator is steady on. If it is off, it indicates that the device is running normally without faults.

Common faults and handling

WARNING : Danger of electric shock. Inputs and outputs are not electrically isolated and may be energized with dangerous solar voltages. Under certain fault conditions, the battery may overcharge. Before making contact, test the impedance between all terminals and ground.
Warning: Danger of electric shock
A means of disconnecting all power electrodes must be provided. These disconnections must be included in the fixed wiring. Disconnect all power supplies before removing the controller wiring cover or repairing the wiring.

Fault

The LCD screen doesn’t light up, and the controller doesn’t seem to be powered on. Solution: Use a multimeter to check the voltage of the battery terminals on the MPPT. The battery voltage must be 10 VDC or higher. If the voltage on the controller battery terminal is between 10 and 60 VDC and no indicator light is on, contact the authorized distributor for repair. If the voltage is not measured, check the wiring, fuses, and circuit breakers.

Fault :
The controller is not charging.

Solution :

Check fuses, circuit breakers, and wiring connections in power wiring. Using a multimeter, check the array voltage directly on the MPPT solar input terminals. Before starting charging, the input voltage must be greater than the battery voltage. Check whether the battery voltage displayed on the LCD screen is within the recognition range of the controller system.

Fault :
The battery has been in a low or dead state for a long time.

Solution :

Possible reasons: 1. There are too few solar panels to generate enough energy to meet the system use, and the solar panel array can be increased appropriately. 2. The battery capacity is too small to store enough energy for the system to use, and the capacity of the battery pack can be appropriately increased.

Maximum 1-way wire distance for 12 Volt systems, solid copper, 2% voltage drop
Attention: *Wires larger than 4 AWG (25 mm2) must be terminated at the combiner box outside the MPPT. Use 4 AWG (25 mm2) or smaller wire to
connect the MPPT to the combiner box.
Attention: • The specified wire lengths are for a pair of wires (one- waydistance) from the solar or battery power source to the controller.
• For a 24-volt system, multiply the length in the table by 2.
