SOLAR HOME SYSTEM General Information. I. Use MCU and professional software as the control center to fulfill intelligent system control. II. The accurate control point depends on the battery discharge rate, final discharging voltage is the control point of corrected discharging curve. eliminate the discrepancy by the single voltage control, meet the battery characteristics, which is different charge rate has different final voltage. III. With intelligent protection against over charging, over discharging, electronicc short-circuit, over load, polarity reverse and etc. no damage for any components, and no burning for the fuse. IV. With series PWM charging circuit, the voltage loss of charging loop is only half of the LED charging circuit, the charging efficiency is higher 3% %-6% than the ON/OFF one, and saved the energy. The boost, direct, and float charging enhanced the lifetime of the system. Also it has specific temperature compensation. V. Direct LED indicator for the statues of the system. With flash memory saving the control make the setting digital, eliminate the discrepancy. VI. One key setting, easy and convenient.
