540V 50A MPPT solar charge controller for solar batteries

Product Description

540V 50A MPPT solar charge controller for solar batteriesMPPT Solar Charge Controller DescriptionThe solar controller adopts multiphase synchronous rectification technology and common negative pole design, it chooses high speed processor and advanced MPPT algorithm to make it has high response speed, high reliability and other standards.The advanced MPPT algorithm that the solar controller adopts can trace the maximum power point of PV arrays quickly in any situation to obtain the max. power from PV arrays. And the multiphase synchronous rectification technology can achieve high conversion efficiency in any charging environment and improve the utilization rate of solar power system greatly. According to the rated voltage of battery bank system, our factory can provide the MPPT solar charge controller from 192V to 540V which suitable to almost off grid solar power systemMPPT Solar Charge Controller FeaturesHigh speed and performance 32bit processor, advanced EMC designAdvanced MPPT tracking algorithm, the tracking efficiency more than 99%High performance IGBT power module as electronic switch, plus multiphase synchronous rectification technology, improves the stable greatlyUltrafast maximum power point tracking speed to ensure tracking efficiencyPerfect battery protection function and advanced battery activation technology which increases battery lifespan 30% at least and improves the system performanceWidely PV arrays voltage input, this can save the cost of PV combiner box, wires and constructionFull enclosed duct design and high speed fan for cooling makes the controller suitable for various harsh environments3 inch LCD screen and LED indicators show working parameters and system statusParameters can be adjusted through touching keys in LCD panelUsers can check the power generation of daily, monthly and total through the statistical function of generating capacity (SOC)Complete menu display and operation, plus the humanized design of browsing interface, makes the operation more easyIt shows the environment temperature, data and real time, auto temperature compensation functionTwice protection function to protect battery from damage when the power switch is downStandard Modbus communication protocol for RS485 or GPRS communication to extend the communication distance (optional function)DNM-540V/50A MPPT Solar Charge Controller Technical ParametersModel: DNM-540V/50ARated system voltage: 540VMax. input solar power: 27KWRated charging current: 50AController properties: MPPTMPPT Efficiency: >99%No. of input for PV arrays: 1 groupOpen circuit voltage (Voc): 850VStart charge voltage: Vbat+10VOver voltage disconnect: VOver voltage reconnect: 675VEqualize charging point: 648VFloat charging point: 621VEqualize charging recovery: 594VOver discharging warning: 472.5VEqualize charging time: 120 Minutes (These parameters can be adjusted according to demands of different type battery)Charge method: Four stages: quick charging (MPPT), equalize charging, float charging and end chargingDisplay: LCD (backlight)+LEDDisplay language: EnglishIndicator light: Abnormal, Charging, BatteryTerminal type: TC series barrier terminalElevation: <2000M, should reduce power if the elevation high than 2000MStorage temperature: -25 to +55CelsiusIP (Ingress protection): IP20Dimension: 494 x 384 x 220mmNet weight: 27KGAfter-sales Service: Lifetime MaintenanceWarranty: 2 YearsCondition: NewCertification: ISO, CEApplication: Solar System Controller, Charger Controller, Solar Working Station, Voltage ControllerRated Voltage: 192-500VDC optional
