Product Introduction
This solar charge controller is designed specially for solar power system and solar DC street lamp. Adopting dedicated computer chips for intelligent charge controller. Using one-click light touch switch to complete all operation and install; Having global protective measure of short circuit protection, overload protection, unique anti inversed connection protective, auto cut off when full of charge and overdischarge,recover. Detailed charging indicator, battery status, loads and all kinds of failure indicator.
This solar charge controller conduct sampling to battery terminal voltage, discharge current, environment temperature which involve battery capacity by computer chips. Calculate by special control model to meet battery charactistic discharge rate and adapt high efficiency PWM battery charge mode to ensure the best status when battery work and prolong battery service life. Also having various of work mode, output mode for choice to meet customers requirements.
Charactistics
1, Using the single chip microcomputer and special software, adopted specialized software based on expert control system, realized intelligent SOC control
2,Temperature compensation used the external temperature sensor,precision is higher with a built-in temperature sensor control
3,Having automatic control for overcharge, discharge, electronic short circuit protection, overload protection, unique anti inversed connection protective, the above protection do not damage any parts and burn insurance
4, Adopted tandem PWM chargie main circuit, make the charging loop voltage loss reduce nearly half than using diode charging circuit, charging efficiency is high 3% ~ 6% compared with PWM and increases power use time;Had overdischarge recover ascension of charging, normal straight charger, floating automatic control method to make the system have a longer service life and a high precision temperature compensation at the same time
5, Intuitive LED luminous tube indicate the current battery status, make users comprehend the status
6,All control adopt the industrial-grade chip, can be run freely in cold, high temperature, damp environment, use the crystals timing control, timing control precision at the same time
7, Using digital LED display and equipment, one-click operation can complete all settings and very convenient
8, With multi-stage single time load time setting, and multistage load time setting can be set up independently of the double time
9, Double session Settings adopted fuzzy control automatic identification and according to the actual correction night shut down load time (accurate to the minutes) to ensure loads only open at set time after it gets darkthe before morning.
