12V/24V , MPPT-40A CHARGE CONTROLLER %

 Solar charge controller MPPT-40 is a 40A photovoltaic battery charge controller. Through the use of MPPT technology, it can increase charge current up to 30% or more compared to conventional controllers. Its 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, reverse current and reverse PV connections. An automatic current limit feature allows use of the full 40 amp capability without worrying about overload or nuisance fuse blow from excessive current, voltage or amp-hour based load control. 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 elements 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 it also includes an isolated RS232 port for connection to a PC computer for data logging and system monitoring. It can be easily installed in parallel connection, so it is also suitable for large system current application condition.
