Solar Charge Controller Model – 8 ( 48V – 20A )
Excellent Charging algorithm, temperature compensated set points. 12V/24V Automatic identification by system. LED digital display and one-key operation, easy to use. The improved 3-section computing method can weekly give the battery a Balanced charging. It can stop the battery from being unbalancing and vulcanizing and let the battery been used for more time. The controller is equipped with the serial PWM charging main circuit with additional 3%~6% efficiency than the non-PWM circuit which can work for more time and increase the using period of the system. Controller has three load work ways and can be easily used in varies streetlights and monitors. Visualized LED display which can let the users get to know the conditions of solar power and storage battery. Overcharge, over discharge and overload protection; Electronic short circuit protection; Reverse connect preventing protection. Lightning prevention.
Controller installation must be stable, the size of overall and installation as below :
- Wire : firstly please check the wires length, confirm the installation position, as less as possible for wire length to cutting the power consumption.
- Connect to the battery: pls note the +(positive pole) and -(negative pole), don’t opposite, if you are right, the battery indicator light will be lighting, or else, you must to check the pole.
- Connect to the solar panel: pls note the +(positive pole) and -(negative pole), don’t opposite, if it is sunny, the charge indicator light will be lighting or charging flicker after about 10 seconds, or else, you must to check the connection.
- Connect to the load: put the dc load(led lighting power) connect cable into the controller output + and – pole, also please note the +(positive pole) and -(negative pole), don’t opposite to avoid damage device and any electric products.
