Safety Instructions and Liability Waiver

Safety

1. the solar charge controller may only be used in PV systems in accordance with this user manual and with solar panel specifications in line with the requirements of this controller. No energy source other than solar panels may be connected to the solar charge controller Batteries store a large amount of energy, never short-circuit a battery under any circumstances.
2. We strongly recommend connecting an in-line fuse or circuit-breaker on the “+” wire between the battery and controller, no more than 15cm from the battery terminal.
3. Batteries can produce flammable gases. Avoid sparks and flames near the batteries. Make sure the battery is installed in a well-ventilated area.
4. Avoid touching or short-circuiting wires or terminals. Be aware that the voltages on special terminals or wires can be several times greater than the battery voltage. Use isolated tools and only perform any work in a dry environment.
5. Keep children away from batteries and the charge controller.

Liability Exclusion

• The manufacturer shall not be liable for damages to the controller or battery caused by use other than as instructed in this manual, or if the battery manufacturer’s recommendations are neglected.
• The manufacturer shall not be liable if there has been service or repair carried out by any unauthorized person, unusual use, incorrect setup, or bad system design.

Dimensions

Installation

The following diagram provides an overview of the terminals. Please make sure to follow the proper order of connection.

1. As the chart, Connect the load first with corresponding red(positive) and black (negative) cables, then seal them with tape.
2. Connect the battery with corresponding positive and negative cables, load will be on.
3. Connect panel with the corresponding red(positive) and black( negative) cables, the controller begins charging.
4. Confirm the LED display status, please refer to the
   • Faults and Alarms to identify the reason.
   • Make sure the wire length between battery and controller is as short as possible.
   • Recommended Wire size: 10A:2.5mm2 15/20A: 4mm2.

Remote control, Default settings

Settings can be changed using the “S-Unit” infrared remote programmer. For detailed instructions and settings, please see the S-Unit programmer remote manual. Be sure to only set one controller at a time.

Reading the parameters

Press the “Parameter” key of the S-Unit to read the setting parameters of the controller

Dimming function, if you set 0%, the load will be off, otherwise, the load will be on.”Load I” and “Dim Auto” settings are for DC series controllers with built-in LED driver, and do not work in this type of controller

Reading the running status

Press the “Status” key of the S-Unit to read the running status of the controller. This will display the current mode of the controller and any measured values

Press the “Test” key of S-Unit, the controller will turn on the load for 30s. During the daytime, this can verify correct installation and help with troubleshooting. In default “24H” mode, the test key is invalid.

Starting up the controller

• Self Test

As soon as the controller is powered, it starts a self-test routine. After this, the LED display will change to normal operation.

• System Voltage

The controller applies to Lithium, AGM, Liquid and Gel battery, the factory default setting is suitable for Gel batteries. It is your responsibility to check and ensure that these settings are correct for your battery, otherwise, they must be amended. When the controller is set to a Lithium battery, the charging target voltage and charging recovery voltage can be set according to customer requirements. The controller adjusts itself automatically to 12V or 24V system voltage when it is set to Gel, Liquid or AGM battery. If the battery voltage on start-up is 10V-15V then the controller infers a 12V system. If the battery voltage is 20V-30V the controller infers a 24V system.If the battery voltage is not within the normal operating range (ca.10 to 15V or ca.20 to 30V) at start-up, please refer to 9.2 Faults & Alarms.

0℃ Charging Protection(Lithium Battery)

“0℃ Chg” can be set to “Yes”, “Slow” or “No”. When the controller detects that the ambient temperature is higher than 0℃, the charging function is normal. when the ambient temperature is low than 0℃, if the “0℃ Chg” is set to “Yes”, the charging function is normal, else if the “0℃ Chg” is set to “slow”, the max charging current is 20%of the rated current, else if the “0℃ Chg” is set to “No”, the controller does not charge the battery

Load Output Timer Modes

Smart-MPPT series controller has advanced day/night time control functions. The modes of lighting can be based on customer needs.

Standard(24H)

If “Time1” is set to “24H” and sent to the controller successfully, the controller’s load will always be on.

Dusk to Dawn (D2D)

If “Time1” is set to “D2D”, the controller works in dusk to dawn mode.

1. The dimming setting will still be active in this mode.
2. If “Time1” is set to D2D mode, “Time4” cannot be set to T0T mode

Five-stage Night Mode

Time 1-5 and Dim 1-5 can be set individually to give variable load power throughout the night.

T0T mode(can set the load on time before dawn)

If “Time4” is set to “T0T”, this mode is T0T mode. If “Time4” is set to “T0T” then the controller will determine Time4 based on Time5 and previous data on the time of sunrise.  While “Time4” is set to T0T mode, “Time1” cannot set to D2D mode

LVD, LVR, Threshold

Low Voltage Disconnect (LVD)

When the battery voltage drops below the LVD voltage, the controller will disconnect the load to prevent deep discharge of the battery  this occurs, the battery should be well charged before resuming use.

Gel, Liquid, and AGM Battery

• Battery capacity control SOC1:
  • 11.0-11.6V/22.0-23.2 V
  • sOC2: 11.1-11.7V/22.2-23.4 V
  • SOC3: 11.2-11.8V/22.4-23.6 V
  • SOC4: 11.4-11.9V/22.8–23.8 V

• Battery voltage contro LVD range:
  • 10.8-11.8V/21.6-23.6V. 2.
• Lithium Battery LVD range: 9.0-30.0V. 8.2
• Low Voltage Reconnect (LVR) If the low voltage disconnect is triggered, the controller will restore load connection only when the battery voltage increases above the LVR voltage. 1. Gel, Liquid and AGM Battery LVR range: 11.4-12.8V/224-25.6. 2.
• Lithium Battery LVR range: 9.6-31.0V. 8.3 Day/Night Threshold, Day/Night Delay The controller recognizes day and night based on the solar array open circuit voltage. This day/night threshold can be modified according to local light conditions and the solar array used. Day/Night threshold setting range: 3.0-20.0V. The actual time of turning on can be delayed by up to 30 minutes from the time the threshold was reached using the Day/Night delay setting (D/N Dly).Day/Night delay time setting range: 0~30min

Day/Night threshold voltage of load disconnect is 1V higher than the setting data, which means the load will disconnect when the solar voltage at 4.0~21.0V.Day/Night threshold voltage of load disconnect is 1V higher than the setting data, which means the load will disconnect when the solar voltage at 4.0-21.0OV. The controller will automatically adjust the day/night threshold. If the lowest solar voltage is higher than the day/night threshold. The load will have no output the first night, then 24 hours later the controller will automatically adjust the setting to give output the following night
