10A 20A 30A solar charge controller for street light
System description
1. 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, the system will identify the voltage when the controllers are charged initially.
2. 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.
3. 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.
4. Intelligent control is realized by using microprocessor and dedicated control calculation.
5. Four load working modes: Pure lighting control, lighting control & timing control, hand operation and debug mode.
6. 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 lifespan is increased. Besides, the adoption of high precision temperature compensation makes the charging more accurate.
7. 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.
8. 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.
9. 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.
10. 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.
11. Digital LED display and one button setup make the device easy to handle.
12. Discharge rate revision controls: Different discharge rate matches with different cut-off voltage, which is in compliance with the characters of storage battery.
