high efficiency charging way. Boost, recovery and float charging auto work for battery long-life and with

temperature compensation. It has high accuracy over discharging control by the discharging rate, overdischarging

control voltage modified by the battery discharging rate curve. Our controller has the function of self

protection from overload, outside and inside short circuit, reverse connection, thunder and lightning, PV panel

reverse current, over charging and discharging etc. During the short circuit and overload protection, no any

component will be damaged and need change, including fuse. The LED will indicate the working state of the

system in charging, overcharging power full, power low, over-discharging, over load, out short circuit, load on/off

and etc. Our products meet the industrial production standard with wide temperature running area -35oC to

+55oC. In order to make sure the control accurate and reliable we use flash memory to save all work control point

instead of adjustable resistance to project the control work point from going off as the adjustable resistance value

is easily changed by temperature and vibration. And our products are easy to operate, robust in design.

It's the second generation of the small solar controller, more reliable, and economical. It is ideal for rural electrification

system.

Characteristics of Controller:Work mode: Start and close lamp use the PV panel voltage as sunlight sensor; light start

lamp and close lamp by the setting time. Time calculation uses crystalline oscillator to sure the time control accuracy. 3. to

be 24hours work mode. 4. Test mode.

Charging mode: use high efficiency charging way. Boost, recovery and float charging auto work for battery long-life. Use

temperature compensation.

Self protection: protection to overload, outside and inside short circuit, reverse connection, thunder and lightning, PV

penal reverse current, over charging and discharging, over system voltage, etc. LED indication on system condition : LED

indicating the system of charging, overcharge, power full, power low, over-discharge, over load, out short circuit, load on/off,

etc. Industry level production standard: wide temperature running area -35 to +50 No adjustable hardware part: use flash

memory to save all work control point instead of adjustable resistance, to protect the control work point from going off as the

adjustable resistance value is easily changed by temperature and vibration, in order to make sure the control accuracy and

reliability.
