high quality 40A solar charger controller solar controller for charging battery

  Product Description   high quality 40A solar charger controller solar controller for charging battery     Specifications 1.protection of battery over charge 
2.simple led display shows working status clearly 
3.Adapt to wide range of temperature The design features  1, PWM multi-way charging: constant voltage, constant current, floating organic combination of intelligent charging mode conversion, no manual settings.  2, High stability: As the system has over voltage, under voltage, overheating, short circuit, reverse polarity, lightning protection, battery open-circuit protection, complete protection, thus ensuring the stability of the system. 
3, LCD display battery voltage and charge status: the LCD displays the battery voltage, charging current, battery status and capacity. So that the product is designed humanized.
4, LED display: Green LED display system status; red LED shows the battery status, when the red LED is flash mean the battery voltage is low, when the red LED constant on mean the battery is full. 
5, Digital intelligent control: combine the hardware and software, so the external circuit structure is simple, thus ensuring excellent performance and stability.     Note PV charge controller has been designed to fully protection, but any protection are not perfect, some features (such as short circuit protection, reverse battery protection ) will start frequently cause great damage to internal components, so users should not only rely on these protective measures, the following precautions for extending the life of the crucial: 
1. Check the system regular, make sure all the part of the system working normally
   a) photovoltaic cells, battery is connected correctly and firmly. 
   b) Whether the rules and procedures manual. 
2. Clean the battery terminal regular, make the connected is good. 3. Reverse battery is strictly prohibited! 4. The machine should be placed in the room staff easy access and well-ventilated place. The machine should not be covered by other items, there should not be near the explosive, flammable!     Company Information   Our factory picture FAQ
