product id: SOLP00048

This controller is 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. When LED shows "0", it means the system voltage is 12V. While shows "1", means 24V.

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 avaialable for the storage battery, so that storage battery is always in the perfect working state. The variouse working modes of controllers can meet customers' different requirements.
