This
controller is for off-grid PV system to 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.
Charging process has been optimized for long battery life and improved system
performance.
