ST4 Series Solar Charge Controller
This controller applies in solar photovoltaic systems, which coordinates the working of solar panels, batteries and loads. It adds several protection functions, so that the entire system can be in efficient and safe operation.
Features:
●CPU controlled with PWM function: able to adjust the charge current and decide if to supply the loads electricity according to the voltage of battery;
●Compensation charging: according to various system temperatures, the controller will automatically compensate the temperature of the charging voltage;
●LCD monitor: showing the charging current, battery voltage, environment temperature and real-time data of the charging process;
●Temperature sensor: probing the temperature of environment and indicating the degree of charging;
●Automatic Identification System Voltage, 12V/24V auto recognition;
●Completed technical data for setup and modify;
●Discharge capacity control;
●Working Storage Function: record the total run time of system,
record timers of error during running time, record times of full
charged battery;
●Over voltage protection, short circuit protection, over load
protection, overcharge protection, over-discharge protection.
Applications:
Solar system.
