exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level. Pulse width modulation (PWM) [3] and maximum power point tracker (MPPT) technologies are
more electronically sophisticated, adjusting charging rates depending on the battery's level, to allow charging closer to its maximum capacity. Charge controllers may also monitor battery temperature to prevent overheating. Some charge controller systems also display
data, transmit data to remote displays, and data logging to track electric flow over time
