MPPT 20A Solar Charge Controller 12V 24V Solar Regulator

With the advanced - or multi- tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum point. A -in maximum point tracking algorithm can significantly the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM .
A combination of multiple tracking algorithms enables tracking of the optimum working point on the I-V curve in an extremely short time. The product boasts an optimum MPPT tracking efficiency of up to 99.9%. Advanced digital supply technologies raise the circuit's energy conversion efficiency to as high as 98%. Charging program are available for different types of batteries including batteries, sealed batteries, open batteries, lithium batteries, etc.
The controller features a limited current charging mode. When the solar panel exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging and bring the charging current to the rated level. Instantaneous current startup of capacitive loads is supported. Automatic recognition of battery voltage is supported.
LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults. Historical data function is available, and data can be stored for up to a year. The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters. The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
The controller employs a -in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat. Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life. This product can keep monitoring the solar panel's generating and tracking the highest voltage and current values (VI) in real time, enabling the system to charge the battery in maximum . It's designed to be used in off-grid solar photovoltaic systems to coordinate operation of the solar panel, battery and load, functioning as the core control unit in off-grid photovoltaic systems.
This product features an LCD screen which can dynamically display the operating status, operating parameters, controller logs, control parameters, etc. Users can conveniently check parameters by the The controller utilizes standard Modbus communication protocol, making it easy for users to check and modify system parameters on their own. Besides, by providing free monitoring software, we give users the maximum convenience to satisfy their varied needs for remote monitoring.
With comprehensive electronic fault self-detecting functions and electronic protection functions inside the controller, component damage caused by installation errors or system failures can be avoided to the greatest extent possible.
