Digital PWM 30A Solar Charge Controller Regulator 12V24V Autoswitch Solar Panel

Description:

- Our controllers are specially designed for solar power DC supply system, solar power DC street lamp system and mini solar power station system. Intelligent control is realized by using dedicated computer chips. The controllers can be used in hard environment, since its adoption of technical grade chips. To the controllers with 12V/24V automatic identification function, 12V and 24V battery auto sensing

- The short circuit, over-load, connection-reverse protection, as well as over-charge, over-discharge protection are available. Besides, the complete indications are usable, including indications for states of charge, storage battery and faults.

- Through the computer chips, the controllers take samples from the parameters of storage battery voltage, photo battery, discharge current and environment temperature, and then use the dedicated control mode calculation to control the discharge rate and make it matched with the characters of storage battery, realize the high accurate temperature compensation. PWM fuzzy charge mode and 7 phase voltage control are available for the storage battery, so that storage battery is always in the perfect working state. The various working modes of controllers can meet customers’ different requirements.

 

 

 

Main features:

- Intelligent control is realized by using microprocessor and dedicated control calculation

- Four load working modes: pure lighting control, lighting control & timing control, hand operation and debug mode

-  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.

- 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.

- 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.

- Using large-diameter wire terminal, can fix the wire which max size is 6mm2

- 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.
