High-quality solar charge controller with built-in USB interface.Precise and gentle charging of the usual solar battery types is guaranteed thanks to the four different charging programs. A wide range of protective measures against overvoltage and overload provide for a safe operation of the solar charge regulator. The overcharge protection and deep discharge protection supports the longevity of the connected solar battery. In addition, you can use the USB interface is a connection between the solar controller and PC build and so user-specific charging program. The two built-in LEDs show the current charge level, warn against deep discharge and the status of the load output again.Charging methodDepending on the defined type and its end-of-charge voltage, the charging in no more than 3 levels. At the end of charging level 1 Charging is done with maximum current until the corresponding charging end voltage is reached. This will still for a defined time with charging level 1 is loaded and then goes in level 2. Here, pulse width modulation (PWM) of the charging current, as limited. The user-specific charging profile can also charge level 3 can be achieved. At a discharge of more than 30 minutes, the device returns to charging mode 1.Low voltage disconnectIn order to protect the battery before irreparable damage in the case of deep discharge, when reaching the discharge voltage, the connected load output is switched off. The load output is switched, depending on the corresponding settings, again, if the battery is sufficiently charged again.Temperature compensationWith the supplied temperature sensor can be an optimization of the end-of-charge voltage to the ambient temperature can be achieved. Also a user-specific temperature coefficient is defined.Configuration and monitoring of the solar controller by means of a PCAn exact mode of operation of the solar controller is implemented through the Battery sense connection possible. Through the free software, you can simply and conveniently on the PC settings, such as charging profile, deep discharge protection, temperature coefficient, function of the load output, the time and date can be carried out. The operating data for the solar charging controller can also be logged and monitored.Voltage Sensor for batteryAn exact mode of operation of the solar controller is implemented through the Battery sense connection possible. Configuration and monitoring of the solar controller by means of a PC: through the free software, you can simply and conveniently on the PC settings, such as charging profile, deep discharge protection, temperature coefficient, function of the load output, the time and date can be carried out. The operating data for the solar charging controller can also be logged and monitored.Programmable load outputThe following four adjustable options are available for the load output possible:1. Load output switches on and off at defined times.2. When the discharge end voltage is reached, the load output for reactivation voltage.3. Night light function: in the absence of solar power switches the load output after 2 minutes, when there is a solar power again.4. When the discharge end voltage is reached, the load output off permanently.This text is machine translated.
