Low power Solar Charge Regulator
The Tortech Solar charger controller is a 40/60 amp 12/24 voltage Maximum Power Point Tracking (MPPT) photovoltaic (PV) battery charge controller. Through the use of MPPT technology, Solar charger controller can increase charge current up to 30% or more compared to conventional controllers. Solar charger controller’s sophisticated three stage charge control system can be configured to optimize charge parameters to precise battery requirements.
The unit is fully protected against voltage transients, over temperature, over current, reverse battery and reverse PV connections. An automatic current limit feature allows use of the full 40 amp capability without worrying about overload 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 environmentally 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 Solar charger controller also includes an isolated RS232 port for connection to a PC computer for data logging and system monitoring. The Solar charger controller can easily install in parallel connection of output, so it also suitable for large system current application condition.
