By intelligently monitoring the battery voltage, this controller ensures that the lithium battery pack is not 

harmed by an output voltage that is either excessively high or low . In doing so, the battery’s lifespan is 

extended. Despite its straightforward architecture, the system exhibits exceptional efficacy. The lithium 

battery and controller device are stable and straightforward to integrate and maintain . Nova split solar 

street lights are appropriate for illumination in off-grid regions, residential and commercial areas, 

roadways and squares, pedestrian and bicycle paths, and parking lots .
