Adisconnect is required for the battery and solar circuits to provide a means for removing power from the charger. Double pole switches or breakers are convenient for  disconnecting both solar and battery conductors simultaneously.

Connect the Power Wires

WARNING: Shock Hazard
The solar modules can produce open-circuit voltages in excess of 100 Vdc when in sunlight. Verify if solar input breaker or disconnect has been opened (disconnected)before connecting system wires.

Connect terminals by following below steps (Refer to diagram above):

1. Make sure that the system input and output disconnect switches are b o t h turned off before connecting power wires to the charger. There are no disconnecting switches inside the charger.

2. Make 4 power wires first. Remove insulation sleeve 10.5mm and the conductor should be plated Tin. Refer to the chart below.

3. Pull all wires into the wiring box. The Remote Temperature Sensor and Battery Sense wires can be inside the conduit with the power conductors. It is easier to pull RTS  and Sense wires before the power cables.
   WARNING: Risk of Damage
   Be sure that the battery connection i s made with correct polarity. Turn on the battery breaker/disconnect and measure the voltage on the open battery wires BEFORE  connecting to the controller. Disconnect the battery breaker/disconnect before wiring to the controller.

4. Connect positive terminal (+) of battery to the battery positive terminal (+) on the controller.

5. Connect negative terminal (-} of battery to one of the Common Negative terminals (-} on the controller.
   WARNING: Risk of Damage
   Be sure that solar connection is made with correct polarity. Turn on the solar breaker/disconnect and measure the voltage on the open wires BEFORE connecting to the controller. Disconnect solar breaker/disconnect before wiring to the controller.

6. Connect positive wire (+) of solar module to the solar positive terminal (+) on the controller.

7. Connect negative wire (-) of solar module to one of the Common Negative terminals (-) on the controller.

8. Screw four (4) power terminals tightly with 50 in-lbs torque. (5.65 Nm)

3.5 Grounding and Ground Fault Interruption
Use a copper wire to connect the grounding terminal in the wiring box to earth ground. The grounding terminal is identified by the ground symbol shown below that is  stamped into the wiring box just below the terminal:

The minimum size of the copper grounding wire is 8 AWG (10 mm2).

WARNING: Risk of Fire
DO NOT bond system electrical negative to earth ground at the controller.

3.6 Remote Temperature Sensor
The included Remote Temperature Sensor (RTS) is recommended for effective temperature compensated charging. Connect the RTS to the 2-pole terminal (see figure as  below). The RTS is supplied with 33 ft (10 m) of 22 AWG (0.34 mm2) cable. There is no polarity, so either wire (+ or -) can be connected to either screw terminal.

The RTS cable may be pulled through conduit along with the power wires. Tighten the connector screws with 5 in-Ib (0.56 Nm) torque.
NOTE: The RTS is optional package. Please check local dealer for the details.

CAUTION: The controller will not activate temperature compensate charging function if the RTS is not used.
CAUTION: Equipment Damage
Never place the temperature sensor inside a battery cell. Both the RTS and the battery will be damaged.
NOTE: The RTS cable may be shortened if the full length i s not needed.

3.7 Battery Voltage Sense
The voltage at the battery connection on the controller may differslightly from the voltage directly at the battery bank terminals due to connection and cable resistance. The  Battery Voltage Sense connection enables the controller to measure the battery terminal voltage precisel y with small gauge wires that carry very littlecurrent , and thus have  no voltage drop. Both battery voltage sense wires are connected to the 2-pole terminal inside o f wiring box (see figure as below).

Be careful to connect the battery positive (+) terminal t o the voltage sense positive (+) terminal and battery negative (-) terminal to the voltage sense negative terminal ( – ) .  No damage will occur if the polarity is reversed, but the controller cannot read areversed sense voltage.

Abattery voltage sense connection is not essential required to operate your controller, but it is recommended
for best performance. The battery voltage sense will ensure that the voltage display in LCD is very accurate.
The voltage sense wires should be cut to length as required to connect the battery to the voltage sense terminal.
The wire size can range from 16 to 24 AWG (1.0 to 0.25mm2). Atwisted pair cable is recommended but not required. Use UL rated 300 Volt conductors. The voltage sense  wires may be pulled through conduit with the power conductors. Tighten the connector screws with 5 in-lb (0.56 Nm) torque. The maximum length allowed for each battery voltage sense wire is 98 ft (30 m).

Reference Code

CHARGING LOGIC

5.1 3-stage Charging
In general, this solar charge controller is designed with 3-stage battery charging algorithm for fast, efficient, and safe battery charging. The following picture shows the sequence of charging stages.

1. Bulk charge stage
   In bulk charge stage, charge current begins to flow, typically at the maximum rate of the charge source. The controller will supply solar power to charge battery as much as possible.

2. Absorption stage
   When battery chargin g voltage is reached to Absorption voltage point, the charging stage changes from bulk charge to Absorption. Constant-voltage regulation is used to maintain battery voltage at the Absorption stage.
   If the charging current drops to one-tenth of the maximum charging current setting point, the charging status will change to Float stage.If the elapsed time of absorption stage is over setting value for C-V charging time, it will also transfer to Float stage.

3. Float Stage
   After the battery is fully charged in the Absorption stage, the controller will reduces the battery voltage to the setting point of Float voltage. Once in Float stage, constant-voltage regulation is used to maintain battery voltage at setting point of float voltage.
   In lithium battery mode: the charging logic has no floating charge stage

• Float timeout
  If the battery voltage remains lower than the Float voltage for 30 minutes, the controller will return to Bulk charging stage.

• Float cancel voltage
  Once the battery voltage drops to setting point of Float cancel voltage, the controller also returns to Bulk charging stage. Float cancel voltage = Floating charging voltage — (1V x battery numbers in series)

5.2 Equalize Stage
Equalization function is added into solar charge controller. It reverses the buildup o f negative chemical effects like stratification, a condition where acid concentration i s  greater at the bottom of the battery than at the top.
Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called su lfation, will reduce the overall capacity of  the battery. Therefore, it’s recommended to equalize battery periodically.![felicity solar SCCM Series MPPT Solar Charge Controller

• charging logic 5](https://manuals.plus/wp-content/uploads/2023/02/felicity- solar-SCCM-Series-MPPT-Solar-Charge-Controller-charging-logic-5.jpg)

When to Equalize
In Absorption stage, if the charging current drops lower than the maximum charging current o f battery equalization, the controller will start to enter Equalize stage.

If solar charge controller is working in float stage, but at this time, the setting equalization interval (battery equalization cycle) is arrived, it will transfer to equalize stage.

Equalize charging time and timeout
In Equalize stage, based on maximum charging current o f battery equalization, the controller will supply solar power to charge battery as much as possible until battery  voltage raises to battery equalization voltage.
Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage. The battery will remain i n the Equalize stage until setting battery equalized time is arrived.

However, in Equalize stage, when battery equalized time i s expired and battery voltage doesn’t rise to battery equalization voltage point, the solar charge controller will  extend the battery equalized time until battery voltage achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when battery  equalized timeout setting i s over, the solar charge control will stop equalization and transfer to float stage.

MPPT charger controller match to the Inverter

In actual application system, MPPT controller and inverter will charge the battery at the same time, the charging current will excessive to occur unsafe situation, so we add the function of matching the inverter to limit the charging current of the battery. However, since it needs to be matched with MPPT of different manufacturers , but the MPPT  charging current cannot be limited.
The current solution is to limit the charging current of the inverter.
The inverter match to the MPPT controller is mainly including two function:

1. Enabling or disable inverter to match the MPPT function. (Special attention: when upgrading the firmware of the inverter, it needs to disable the function matching  MPPT first);
2. Limited the charging current of the inverter. The methods are as follows:
   a) When the MPPT charging current 2 inverter setting charging current, the maximum allowable charging current of the inverter equal to 0;
   b) When the MPPT charging current < inverter setting charging current, the maximum allowable charging current of the inverter equal to inverter setting charging  current subtract MPPT charging current;

8.1 Match the inveter to the MPPT controller:

1. To enable the inverter to match the MPPT controller, the inverter and MPPT controller should be switched on first, and the communication lines between them have  been connected;
2. Then press the “Down’button of the inverter for more than 2.5 seconds, until the MPPT charger icon flashes. At this time, you can release the button. The icon flashing  indicates that the inverter is trying to communicate with the MPPT. The inverter is releasing. After pressing the button for 10 seconds, the icon stops flashing. When the  communication is successful, it means that the function is successfully enabled.
3. After successfully enabling, the matching MPPT function flag will be saved in the EEPROM. Restarting the inverter does not need to be manually enabled again.
4. After successfully enabling, turning the page on the LCD screen will display MPPT PV voltage, power and other information.

red box in the right picture flashes, indicating that the inverter is trying to communicate with MPPT. The icon stops flashing after the inverter loosens the button for 10 seconds.|

8.2 Matching MPPT function is prohibited:

1. To prevent the inverter from matching the MPPT function, the MPPT should be turned off or the communication connection between the two should be disconnected.
2. Then long press the “Down”button of the inverter for more than
   2.5 second, until the MPPT charger icon flashes. At this point, the button can be released. The flashing icon indicates that the inverter is trying to communicate with MPPT. The flashing icon will stop 10 seconds after the button is released. When communication fails, it means it is forbidden successfully.

the red box in the right picture flashes, indicating that the inverter is trying to communicate with MPPT. The icon disappears after the inverter loosens the button for 10 seconds.|

8.3 Matching MPPT function successfully enabled:

the MPPT function is successfully enabled, the icon in the red box in the right picture will appear|
Match MPPT function to enable successfully| If MPPT is not in the charging state, but
PV voltage is greater than 30V and s in
the startup state: When the MPPT function is successfully enabled, the icon in the red box in the right picture will appear|

8.4 Matching MPPT function is prohibited successfully:

enabled, the LCD interface page fuming will display PV voltage, power and other information:
