MPPT Technology:

This solar charge controller utilizes advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels. This point varies depending on sunlight exposure and temperature, and the technology ensures maximum efficiency of your solar system. It outperforms standard PWM solar controllers and has a wide solar input voltage range, allowing it to work with a variety of solar panels. For a 12V battery system, the maximum combined input solar power allowed is 260W, and for a 24V system, it's 520W.

Full System Protection:

The charge controller includes a range of electronic protection functions, such as reverse current prevention at night, automatic cut-off to prevent over-charging and deep discharge, solar panel over-voltage protection, over-load protection, short circuit protection, and reverse polarity protection. It also has self-diagnostic capability and can highlight system errors using advanced fault-targeting technology. Additionally, there is an optional audible alarm to alert the user of any system failures.

Additional Features:

The controller automatically recognizes 12/24V battery systems and has LED lights to indicate charging status and battery condition. It also features a current limiting function, die-cast aluminum design for heat dissipation, and multiple connectivity options. These options include connection to a remote meter with an LCD screen, a Wi-Fi module for monitoring and adjusting parameters through a mobile app, and connection to a PC/laptop using an RJ45 to USB cable.

Using one of these communication methods, the user can access various charging parameters such as voltage, current, battery state of charge, accumulated charge and discharge energy, min/max voltage, and more. Additionally, the controller has a socket for connecting a remote temperature sensor to measure the battery temperature more precisely and optimize the charging process.
