USER MANUAL MSC4010 Mestic

The Shiner series controller adopts the industry-leading MPPT to achieve the maximum energy tracking for the solar panel, that is, it can quickly and accurately track the maximum power point of the solar battery on any condition, and obtain the maximum energy of the solar panel in real time, signicantly improving the energy utilization rate of the solar system. It is widely used as the core control component in the off-grid PV systems to manage the work of solar panels, batteries, and loads. Besides, it has complete software and hardware fault detection and protection functions to avoid damage to product components caused by installation errors and system faults to the greatest extent. The Maximum PowerPoint Tracking (MPPT) system is an advanced charging technology with more energy output from the solar batteries by adjusting the operating state of the electrical modules. Due to nonlinearity of the solar battery array, there is a maximum power point on its curve. The PWM charging technology used in the traditional controller cannot charge the battery continuously at the point, so it cannot obtain the maximum energy of the solar panel. Instead, the solar controller with MPPT can always track the maximum power point of the array, so as to charge the battery with maximum energy. For example, for the 12V solar system, since the peak-to-peak voltage (Vpp) of the solar battery is about 17V, but the battery voltage is about 12V, therefore, when the common charge controller is charging the battery, the voltage of the solar battery is about 12V, that is, the solar battery does not fully exert its

ENENThe MPPT controller can overcome the problem and adjust the input voltage and current of the solar panel in real time to reach the maximum input power. Moreover, compared with the traditional PWM controller, it can exert the maximum power of the solar battery to provide a larger charging current. Generally speaking, it can improve the energy utilization rate by 15%~20% than the PWM PWM charging

MPPT point Fig. 2-1 Battery panel output characteristic curve The maximum power point often changes due to the different ambient temperature and lighting conditions. And the MPPT controller is able to adjust the parameters in real-time under different conditions, thus making the system status always near the maximum operating point. The whole process is completely automatic without any adjustment. As light intensity decreases,the current decreases.And as light intensity decreases, the open-circuit voltage decreases.

ENENSelect such battery types as SLD/FLD/GEL/USE, and select the appropriate system voltage. As shown in Fig. 4-1, the charging stages of lead-acid battery are: MPPT charging, constant voltage charging (equalizing/ boost/oating charging), and current-limiting charging.The constant voltage charging is divided into three stages:equalizing charging, boost charging and oating charging:[MPPT charging] When the battery voltage has not reached thetarget constant voltage value, the controller will perform MPPT charging. When the battery voltage reaches the constantvoltage value, it will automatically exit MPPT charging and switch to constant voltage charging (equalizing/boosting/oating charging).[Equalizing charging] Regular equalizing charging is good for some batteries. Equalizing charging is mainly to make the charging voltage of battery higher than the standard supplementary voltage, besides, it can vaporize the battery electrolyte to balance the battery voltage and complete relevant chemical reaction. Equalizing charging and boosting charging arenot repeated during one full charging to avoid excessive gas evolution or overheating of the battery.Notes:1) Since the equalizing charging of oored lead-acid battery produces explosive gas, the battery compartment must bewell ventilated.2) Although the equalizing charging elevates the battery voltage, it may damage the level of sensitive DC loads, therefore, it is necessary to verify that the allowable input voltage of all loads in the system is greater than the set battery voltage value in equalizing charging.3) Excessive charging and excessive gas evolution may damage the battery plate and cause the active substances on thebattery plate to fall off.Besides, excessive high equalizing charging voltage or excessive long equalizing charging duration may damage the battery. Please set relevant parameters according to the specications of the battery used in the system. [Boost charging] The duration of boost charging is 2 h (default). When the duration reaches the set value, the system will switch to oating charging. [Floating charging] Floating charging is the last constant voltage charging stage in the charging cycle of lead-acid battery. The controller keeps the charging voltage constant at the oating charging voltage. At this stage, the battery is charged with a very weak current to ensure that the battery is in full-charging. When the battery voltage is as low as the reconnect voltage of boost charging, the system will exit the oating charging stage and re-enter the next charging cycle.Fig. 4-1 Charging curve of lead acid batteryChargingvoltage Time Equalizing charging voltage MPPT Boost charging voltageFloating charging voltageCharging reconnect voltageConstant voltageFloatingChargingcurrent Time Select such battery types as LI/USE LI, and select the system voltage from 12V/24V. As shown in Fig. 4-2, the charging stages of lithium battery are: MPPT charging/boost charging/ current-limiting charging. [MPPT charging] When the battery voltage does not reach the target constant voltage value, the controller conducts MPPT charging to charge the battery with maximum solar power, when reaches, it automatically switches to boost charging. [Boost charging] In the boost charging stage of lithium battery, when the battery voltage is lower than the boost charging voltage, the system conducts MPPT charging or current-limiting charging, when reaches, it switches to boost charging.
