High efficiency 40A MPPT solar charge controller with LCD display and 5m cable for solar panels up to 520W (12V) / 1040W (24V) up to 150V

MPPT Technology: This solar charge controller uses advanced Maximum Power Point Tracking (MPPT) technology to maximize the efficiency of your solar system. It can work with standard 12/24V solar panels as well as high voltage or multiple panels with voltage up to 150V. The maximum combined input solar power allowed for this controller is 520W for a 12V battery system or 1040W for a 24V system. 

Full system protection: The controller offers a comprehensive set of electronic protection functions including reverse current protection, over-charging and deep discharge prevention, solar panel over voltage, over load, short circuit, and reverse polarity protection. It also has self-diagnostic capability to identify any system errors.

Remote meter/display: The controller includes a remote LCD meter with a 5m cable to display various charging parameters, accumulated charge and discharge energy, and more. 

Factory default or personalized charging: You can choose to use standard factory settings or personalize charging parameters such as battery type and capacity, charging volts for different stages, duration of each charging stage, and load settings.

Additional Features: This controller is compatible with sealed, gel, flooded or user-defined lead acid batteries and can automatically recognize 12/24V battery systems. It also features a current limiting function (40A) and can work with more solar panels in the future. 

Specifications: The controller uses MPPT technology, offers fully automated operation, and features auto 12/24V selection. It also has multiple electronic protection features, communication port, grounding, current limiting function, and more. The remote meter has its own specifications including self-consumption, operating temperature, communication cable, size, and weight.

Warranty and Support: The solar charge controller is covered by a 2-year warranty and comes with a detailed user manual.

Free support for installation and technical questions is also available.

The product comes with a detailed user manual explaining wiring and operations, as well as a section on MPPT technology. Additionally, user manuals for the documents mentioned are available for download.
