Explanation

  1. CD Connection for a RTS (Remote Temperature Sensor) to remotely detect battery temperature.
  2. Monitor controller by PC and update controller software via RS485 (RJ45 interface).

Accessories Instructions

  1. Remote Temperature Sensor (Model: RTS300R47K3.81A)
    Acquisition of battery temperature for undertaking temperature compensation of control parameters, the standard length of the cable is 3m (length can be customized). The RTS300R47K3.81A connects to the port (3th ) on the controller.
    NOTE: Unplug the RTS, the temperature of battery will be set to a fixed value 2s0c.

  2. Remote Meter ( Mode l: MT50)
    The digital remote meter displays system operating information, error indications, parameters setting and self-diagnostics.

  3. Super Parameter Programmer ( Mode l: SPP-02)
    The SPP-02 can realize one-key setting operation which is suitable for bulk quantity products setting in the projects.

  4. USB To RS-485 converter ( Mode l: CC-USB-RS485-150U)
    USB To RS-485 converter is used to monitor each controller on the network using Solar Station PC software and update the firmware. The length of cable is 1.5m. The CC-USB-RS485-150U connects to the RS-485 Port on the controller.

Maximum Power Point Tracking Technology
Due to the nonlinear characteristics of solar array, there is a maximum energy output point (Max Power Point) on its curve. Traditional controllers, with switch charging technology and PWM charging technology, can’t charge the battery at the maximum power point, so can’t harvest the maximum energy available from PV array, but the solar charge controller with Maximum Power Point Tracking (MPPT) Technology can lock on the point to harvest the maximum energy and deliver it to the battery.
The MPPT algorithm of our company continuously compares and adjusts the operating points to attempt to locate the maximum power point of the array. The tracking process is fully automatic and does not need user adjustment.
As the Figure 1-2, the curve is also the characteristic curve of the array, the MPPT technology will ‘boost’ the battery charge current through tracking the MPP. Assuming 100% conversion efficiency of the solar system, in that way, the following

formula is established

Normally, the VMpp is always higher than Vsat, Due to the principle of conservation of energy, the lsa1 is always higher than lpv. The greater the discrepancy between VMpp &Vsat, the greater the discrepancy between lpv& lsat• The greater the discrepancy between array and battery, the bigger reduction of the conversion efficiency of the system, thus the controller’s conversion efficiency is particularly important in the PV system.
Figure 1-2 is the maximum power point curve, the shaded area is charging range of traditional solar charge controller (PWM Charging Mode), it can obviously diagnose that the MPPT mode can improve the usage of the solar energy resource. According to our test, the MPPT controller can raise 20%-30% efficiency compared to the PWM controller. (Value may be fluctuant due to the influence of the ambient circumstance and energy loss.)

Figure 1-3 Mutil-MPP Curve Figure 1-2 Maximum Power Point Curve

In actual application, as shading from cloud, tree and snow, the panel maybe appear Multi-MPP, but in actually there is only one real Maximum Power Point. As the below Figure 1-3 shows:

Figure 1-3 Mutil-MPP Curve

If the program works improperly after appearing Multi-MPP, the system will not work on the real max power point, which may waste most solar energy resources and seriously affect the normal operation of the system. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately, improve the utilization rate of the array and avoid the waste of resources.

Battery Charging Stage
The controller has a 3 stages battery charging algorithm (Bulk Charging, Constant Charging and Float Charging) for rapid, efficient, and safe battery charging.

Figure 1-4 Battery changing stage Curve

Bulk Charging
In this stage, the battery voltage has not yet reached constant voltage (Equalize or Boost Voltage), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging).

Constant Charging
When the battery voltage reaches the constant voltage setpoint, the controller will start to operate in constant charging mode, this process is no longer MPPT charging, and in the meantime the charging current will drop gradually, the process is not the MPPT charging. The Constant Charging has 2 stages, equalize and boost. These two stages are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of battery.

Boost Charging
The Boost stage maintain 2 hours in default, user can adjust the constant time and preset value of boost voltage according to demand.
The stage is used to prevent heating and excessive battery gassing.

Equalize Charging

WARNING: Explosive Risk!
Equalizing flooded battery would produce explosive gases, so well ventilation of battery box is recommended.

CAUTION: Equipment damage!
Equalization may increase battery voltage to the level that damages sensitive DC loads. Verify that all load allowable input voltages are 11 %greater than the equalizing charging set point voltage.

CAUTION: Equipment damage!

Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them. Too high an equalizing charge or for too long may cause damage. Please carefully review the specific requirements of the battery used in the system.
Some types of batteries benefit from equalizing charge on a regular basis, which is able to stir electrolyte, balance battery voltage and accomplish chemical reaction. Equalizing charge increases battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte.
The controller will equalize the battery on the 28th each month. The constant equalization period is 0~180 minutes. If the equalization isn’t accomplished in one-time, the equalization recharge time will be accumulated until the set time is finished. Equalize charge and boost charge are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of battery.

NOTE

  1. Due to the influence of ambient circumstance or load working, the battery voltage can’t be steady in constant voltage, controller will accumulate and calculate the time of constant voltage working. When the accumulated time reach to 3 hours, the charging mode will turn to Float Charging.

  2. If the controller time is not adjusted, the controller will equalize charge battery once every month following the inner time.
    C) Float Charging

  3. After the Constant voltage stage, the controller will reduce charging current to Float Voltage setpoint. This stage will have no more chemical reactions and all the charge current transforms 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 and 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.

  4. In Float charging stage, loads are able to obtain almost all power from solar panel. If loads exceed the power, the controller will no longer be able to maintain battery voltage in Float charging stage. If the battery voltage remains below the Recharge Voltage, the system will leave Float charging stage and return to Bulk charging stage.

PVarray maximum power
This MPPT controller has a limiting function of charging current, the charging current will be limited within rated range, therefore, the controller will charge the battery with the rated charging power even if the input power at the PV exceeds.
The actual operation power of the PV array conforms to the conditions below

  1. PV array actual power s controller rated charge power, the controller charge battery at actual maximum power point.
  2. PV array actual power > controller rated charge power, the controller charge battery at rated power.
    If the PV array higher than rated power, the charging time at rated power to battery will be longer, more energy to battery yields.

WARNING: Controller will be damaged when the PV array straight polarity and the actual operation power of the PV array is three times greater than the rated charge power!
WARNING: Controller will be damaged when the PV array reverse polarity and the actual operation power of the PV array is 1.5 times greater than the rated charge power!

When the PV array straight polarity, the actual operation of the PV array must NOT exceed three times of rated charge power, When the PV array reverse polarity, the actual operation must NOT exceed 1.5 times. For real application please refer to the table below

Protections, Troubleshooting and Maintenance

Protection

  • PV Over Current
    The controller will limit battery charging current to the Maximum Battery Current rating. Therefore an over-sized solar array will not operate at peak power.

  • PV Short Circuit
    When PV short circuit occurs, the controller will stop charging. Clear it to resume normal operation.

  • PV Reverse Polarity
    Fully protection against PV reverse polarity, no damage to the controller will result. Correct the misfire to resume normal operation.

WARNING: Controller will be damaged when the PV array straight polarity and the actual operation power of the PV array is 1.5 times greater than the rated charge power!

  • Battery Reverse Polarity
    • Fully protection against battery reverse polarity, no damage to the controller will result. Correct the misfire to resume normal operation.
  • Battery Over voltage
    • When battery voltage reach to the voltage set point of Over Voltage Disconnect Voltage, the controller will stop charging the battery to protect the battery overcharge to break down.
  • Battery Over discharge
    • When battery voltage reach to the voltage set point of Low Voltage Disconnect Voltage, the controller will stop discharging the battery to protect the battery over discharged to break down.
  • Battery Overheating
    • The controller detect the battery temperature through the external temperature sensor. If the battery temperature exceeds 65°C, the controller will automatically start the overheating protection to stop working and recover below 50 °C.
  • Load Overload
    • If the load current exceeds the maximum load current rating 1.05 times, the controller will disconnect the load. Overloading must be cleared up through reducing the load and restarting controller.
  • Load Short Circuit
    • Fully protected against load wiring short-circuit. Once the load shorts (more than quadruple rate current), the load short protection will start automatically. After five automatic load reconnect attempts, the fault must be cleared by restarting controller.
  • Damaged Remote Temperature Sensor
    • If the temperature sensor is short-circuited or damaged, the controller will be charging or discharging at the default temperature 25 °C to prevent the battery damaged from overcharging or over discharged.
  • Controller Overheating
    • If the temperature of the controller heat sinks exceeds 85 °C, the controller will automatically start the overheating protection and recover below 75 °C.
  • High Voltage Transients
    • PV is protected against small high voltage surge. In lightning prone areas, additional external suppression is recommended.
