Solarmate a 40amp 12/24V volt Maximum Power Point Tracking(MPPT) PV battery charge controller. Through the use of MPPT technology, Solarmate can increase charge current up to 30% or more compared to conventional controllers. Solarmate's sophisicated three stage charge control system can be configured against voltage transients, over temperature,over current, reverse battery and reverse PV connections. An automatic current limit feature allows use ofthe full 40 amp capacity wihtout worrying about overload or nuisance fuse blow from excessive current ,voltage or amp-hour based load control.
Series pass Pulse Width Modulation (PWM) charge voltage control combined with a multistage charge control algorithm leads to superior charging and enhanced battery performance . The filtered PWM power control system uses highly efficient and reliable power MOSFET transistors. The MOSFET's are turned on and off at high frequency to precisely control charge voltage and MPPT.
Fully automatic temperature compensation of charge voltage is available to further improve charge control and battery performance. The optional battery temperature sensor is built for long term reliability. The sensor element is enviromentally sealed and encapsulated into a plastic lug which adheres to directly to the battery terminal and by RJ11 port connect with the unit ,and the solarmate also includes and isolated RS232 port for connection to a PC computer for data logging and system monitoring. The Solarmate can easily install in parallel connection, so it also suitable for large system application condition.
