Product Specification

Battery Charge MPPT Solar Charge Controller 12V 24V 700W 20A With LCD Display For Home Use

Product Feature 

SECM series solar MPPT controllers are intelligent controllers specially designed for small off-grid photovoltaic power generation systems. Based on the advanced MPPT control algorithm design, this series of products adopts an integrated all-cast aluminum heat dissipation shell, which is elegant, economical and practical.

In any environment, it can quickly track the maximum power point of the photovoltaic array, obtain the maximum energy of the solar panel in real time, and significantly improve the energy utilization rate of the solar system. This series adopts the communication interface of standard MODBUS communication protocol and the use of remote GPRS, which is convenient for users to expand applications and meet different monitoring needs to the greatest extent. It can be used in communication base stations, household systems, RV systems, street lighting systems and field monitoring field. With USB charging function, it can be used for mobile phone charging and other occasions. Comprehensive electronic fault self-test function and powerful electronic protection function can avoid the damage of system components due to installation errors and system failures to the greatest extent.

Protection

Solar anti-reverse charging: In the case of poor light such as at night, the voltage of the battery may be higher than the terminal voltage of the solar cell array. The controller has an anti-reverse charging circuit to prevent the battery from reverse charging the solar cell.

Reverse battery connection protection: When the battery is reversely connected, the controller will not work and no display will be displayed. An internal fuse protects the controller circuit. If the battery does not work properly after connecting the positive and negative poles of the battery correctly, just replace the fuse.

Battery open circuit protection: After long-term use, the battery may have an open circuit or poor contact. The controller will protect the device itself from damage when the battery is open circuited. Please check the wiring connections regularly.

overvoltage and Load overload protection: When the battery voltage reaches the overvoltage point, the controller will disconnect the photovoltaic charging circuit. The controller load will automatically cut off the circuit in case of overload.

Power failure protection: When the controller is working normally, when the battery falls off or the lithium battery protection board is protecting, the controller will stabilize the photovoltaic voltage at the equipment working voltage point to prevent equipment damage.

Lightning protection: Lightning protection refers to the last level of protection necessary for equipment. For lightning-prone areas, it is necessary to use a multi-level lightning protection system composed of special lightning protection devices. If the user has this requirement, it is necessary to increase the corresponding power distribution system and cost, which should be stated when ordering.
