The charge controller is a key component of a solar power system and specifying the best one for the system requires some analysis.
The two types of charge controllers most commonly used in today’s solar power systems are pulse width modulation (PWM) and maximum power point tracking (MPPT). Both adjust charging rates depending on the battery's charge level to allow charging closer to the battery’s maximum capacity as well as monitor battery temperature to prevent overheating.
GEESYS MPPT solar controller with Microcontroller technology is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic(PV) systems. The controller features a smart tracking algorithm that maximizes the energy harvest from the PV and also provides load control to prevent over discharge of the battery.
The GEESYS MPPT is well suited for both professional and consumer PV applications including automatic lighting control. Its charging process has been optimized for long battery life and improved system performance. This product is epoxy encapsulated for environmental protection, may be adjusted by the user via four settings switches or connection to a personal computer, and has an optional remote meter and battery temperature sensor.
