WATTSTUNDE® 60 A 140 V MPPT solar charge controller WLR-BT 60,140 MPPT 12 / 24 / 36 / 48 V

MPPT Solar Charge Controller with LCD and Bluetooth Function from WATTSTUNDE®

Generate Your Own Electricity with the Advanced MPPT Solar Charge Controller from WATTSTUNDE® – Perfect for Your Motorhome, Caravan, Boat, and Any Off-Grid Solar System!

The MPPT solar charge controller from WATTSTUNDE® is the central component of any solar system, connecting PV modules, loads, and the solar battery. Its innovative MPPT (Maximum Power Point Tracking) technology converts the variable voltage from the solar panels into a constant voltage, charging your battery efficiently and gently. Even in less than ideal lighting conditions, energy generation remains efficient.

The WLR-BT 60.140 from the MPPT series features a new LCD display that clearly presents a variety of information and measured values. Get precise data on the battery's state of charge or the load current, allowing you to maintain a comprehensive overview of your solar system at all times. This enables you to check your system whenever necessary and make adjustments if needed.

Real-time display of energy flows and a statistics function for monitoring total solar yields make the charge controller particularly user-friendly.

The charge controller quickly and gently charges all common battery types (lead-acid, AGM, gel, lithium). The integrated low-voltage protection prevents dangerous deep discharges of the battery, while the intelligent load disconnection disconnects connected loads when the battery's state of charge becomes critical.

Maximize Your Solar Yield with the Smart MPPT Technology of the WATTSTUNDE® WLR 60.140. This technology optimizes the operating point of the solar panels multiple times per second and efficiently converts excess voltage into increased charging current. This results in shorter charging times and maximum power output – with up to 30% more yield compared to conventional PWM charge controllers.

Even in unfavorable lighting conditions, such as overcast skies or diffuse light, the MPPT charge controller achieves impressive energy yields. Automatic detection of the system voltage (12 or 24 V) and an external temperature sensor that adjusts the charging voltage to the ambient temperature ensure optimized charging performance. Overload and overcharge protection, as well as reverse current protection for the solar panels, provide additional safety for your system.

Highlight:

View Data Live on Your Smartphone! With a Bluetooth-enabled smartphone, you can view a lot of data in real time. Use the wireless connection to easily set up, monitor, and update your controller – all conveniently via your Apple or Android smartphone, tablet, or other devices.
