Over-load and short circuit protection

Overload protection: when the current of controller is 1.25 times of the rated current, the controller works for 30 seconds; 1.5 times of rated current, works for 5 seconds Short circuit protection: when the current of controller is more than or equal to 3 times of rated current, the protection starts.

Circuit protection

Over-charge, over-discharge, short circuit and over-load protection

All the protections are harmless to any parts and fuse of controller

Anti- connection-reverse protection for solar battery and storage battery.

>SOLAR CHARGE INTELLIGENT PV CONTROLLER PRODUCT 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 ream 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. TVS thunder proof protection is also available. Non wire jumpers design improves the reliability and durability of the products.

Technical 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.

Discharge rate revision controls: Different discharge rate match

es with different cut-off voltage, which is in compliance with the characters of storage battery.

Digital LED display and one button setup make the device easy to handl.
