Off-grid System MPPT Solar Charge Controller 30A 12V 24V With Warranty For Solar Panel​

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.

Before installing, make sure you can't install a live state on your laptop while installing. It has nothing to do with the internal installation of safety equipment, dry and ventilated installation, and prevent leakage and direct sunlight. ASAP space or reliable application deployment. Maintenance from the human body for installation, electrical installation and strong electromagnetic interference. If you want to shake the wire output to make the insulation layer, ignite the surface material, or even cause a fire, make sure that the connectors are tightened, and the wires are best fixed, so as to avoid loose wire connectors when moving. There may be voltage on the terminals when connecting the system components. When the operation requires, pay attention to the use of insulated tools and ensure that they are dry. The battery connection terminals in the manual can also be connected with one battery, and can be connected with a group of batteries. When a single battery is used, it is also applicable to a group of batteries.

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.
