[. . . ] LYNCOM MODEL N25T PV SYSTEM LIGHTING CONTROLLER Lyncom's microprocessor based charge controllers incorporate state-of-the-art design and advanced pulse-width-modulation (PWM) battery charging operation, offering the highest quality and more features than comparably priced PV controllers. [. . . ] Model N25T features an automatic load timer, which senses dusk by the solar array and initiates the lighting time period, which is field adjustable. The Model N25T lighting timer can be pre-set for operation of 2, 4, 6, 8, 10 hours, or from dusk to dawn. A low battery voltage load disconnect circuit (LVD) prevents battery over-discharge during extended overcast periods. Model N25T features four system status LED's and a red reverse polarity LED for PV or battery.
