Overview
The controller is for off-grid solar system and control the charging and discharging of the battery, especially suitable for street light system. The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.
The controller charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.
Although the controller is very simple to configure and use, please take your time to read the operator’s manual and become familiar with the controller. This will help you make full use of all the functions and improve your solar PV system.
