Intelligent control is realized by using microprocessor and dedicated control calculation¡£
Five load working modes: pure lighting control, lighting control & timing control, hand operation and debug mode.
Using large-diameter wire terminal, can fix the wire which max size is 6mm
Parameter is set to power-down save function, the system model and control parameters, and other important data are stored inside the chip, after power is not lost, to make the adjustment more convenient, more reliable system.
Using 2 digital LEDs display and settings, one-button operation to complete all of the settings, intuitive and easy to use.

Let the little children away from the storage battery and the controller
1*Digital PWM 30A Solar Charge Controller
Industrial-grade chips and precision components are adopted for all the controls. Therefore, the controller performs well in very low and high temperature, as well as humid environment. At the same time, with the use of crystal timing control, the timing function of controller is much more reliable.
Various protections include over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverse protection. All the protections are harmless to any parts and fuse; fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage. None wore jumpers design improves the reliability and durability of the products.
Scientific management of battery: as it is overcharged, the battery will get booster tension charge. As a result compulsory maintenance is available for the battery. In normal working state, the direct charge and floating charge are both available, so that the battery life-span is increased. Besides, the adoption of high precision temperature compensation makes the charging more accurate
Comparing with the charging loops using diodes, the one that adopts double MOS series circuit control makes the voltage loss dropped by 50%. With the PWM fuzzy control in charging, the charge efficiency is improved a lot.
LED screen shows the working state of solar battery, storage battery and load. LED shows the adjusted parameter. In this way, users can learn the operation state in real time. Besides, there are various choices for parameter; users can select the proper working mode based on the different conditions.
