WATTSTUNDE 40A 90V MPPT Charge Controller WSL40100

The WATTSTUNDE 40A 90V MPPT charge controller WSL40100 is a controller that can be connected between a solar panel and a battery. The alternating voltage of the solar panel is converted into a constant voltage to charge the battery. The innovative method of measuring the maximum power (in short MPPT) makes it possible to generate additional yields even when the weather conditions are unfavorable.

The new WPT 40.100 charge controller from the MPPT series has a built-in LCD display in which you have a visual control of the charging process, the voltage, the status of the battery, as well as the time and temperature. In this way, the system is easy to monitor.

With the help of intelligent disconnection in the charge controller, the battery will automatically disconnect its charge with the connected device when it has reached a critical charge status. In this way the battery is protected against too deep a discharge.

The new WSL-MPP series from WATTSTUNDE is equipped with the MPPT (Maximum Power Point Tracker) system. With the MPPT technology, the controller determines the optimal operating point of the solar panel several times per second. It can therefore transform the voltage surplus of the panels into an increased charging current for the battery. This charging current amplification ensures shorter charging times and optimum power consumption of the system. Compared to a simple PWM charge controller, this ensures a higher yield of up to 30%. Especially during cloudy conditions.

The system voltage with a 12V or 24V battery is automatically detected. With the external temperature sensor the charging voltage can be adjusted automatically, depending on the ambient temperature. Furthermore, the charge controller has the following protections; overcharging and the prevention of discharge of the battery via the solar panel (at night). In addition, there are protections against polarity reversal, too high a voltage of the solar panel, short-circuit and overload.
