This controller is designed for DC power supply system, small and medium-sized pv modules
power system, using a dedicated computer chip to realize the intelligent control, all chips adopt
industrial level, can be used in harsh environment. Meanwhile system offers specific indication
for the charge, load , sorts of failure and various protections such as short circuit, over-load, over
charge, particular anti-reversed polarity protection and so on, the controller used computer chip
to sample the parameter of the battery voltage, photovoltaic cell voltage, discharge current and
environment temperature. According to the battery’s character, realized the accurate control to
discharge rate, correction of the temperature compensation through special control model
calculation.charging with the intelligent PWM dim way and charging compensation in
accordance with the current temperature of the battery, compensation factor is 3mv/℃/unit.LCM
could show all of the parameters and modes. Dial switch need to adjust if adopting different
voltage system.
The controller carried with LCM module which can display system status and parameters
Begin to ascending charging automatically when the voltage of battery below the ascending charging
recover voltage
Temperature compensation become more accurate due to Double temperature sensors design,inner
temperature sensor test the inner temperature of the controller， outer temperature sensor test the
outer temperature of the controller.
The controller could figure out everyday’s power of charge and discharge which make user assess
the controller and entire system more easily
With the charging current overload protection function, the controller will reduce the charge current to
protect the charging circuit after it surpass the rated current.
A equalizing charge every 30 days in order to prevent battery vulcanization
Industrial-grade chips and precision components makes the controller can operate in any harsh
environment
Design of double MOS series control circuit and PWM dim control make the charging efficiency
increased greatly
The setting parameter possess the saving function which makes the parameter won’t be erased after
losing the electricity and system become more reliable.
Three kinds of load work mode: purely light-operated, light-otime controlled,long-term on
mode.

Attention
Read the instruction and attention carefully before use
Do not disassembly and repair the controller freely
Avoid direct sunlight and pay attention to ventilation When installation
Install appropriate fuse or circuit breaker on the outside of the controller
Disconnect the external fuse or circuit breaker when wiring
Be careful to prevent short-circuit when installing the battery
To ensure adopt the correct wire diameter, connect firmly, fasten the wire after connection
Temperature resistance should be fixed on the battery,the othe end connect to the controller
