160W Solar Off-Grid System Kit, Solar Charge Controller 20A LR20ALCD, 2xUSB 12/24V

160W solar kit off-grid system with WATTSTUNDE LR20ALCD charge controller

The convenient start with your own self-sufficient solar power supply.

Free yourself from the power grid and gain your first experience with our solar kits and complete sets.

The complete sets in the beginner series are carefully assembled, and the high-quality components ensure independence from the public power grid. A special feature is that the charge controller can be freely selected according to your preferences.
Take advantage of the opportunity today to electrify your allotment garden, holiday home or barn - the 160 W solar kit makes it easy to set up a 12 V off-grid system.

Easy installation, quick setup and pre-prepared materials make your assembly a breeze!

The set consists of:

• 160 W-HV SOLA Frame monocrystalline solar module with MC4 connectors
• 20A PWM solar charge controller LR20ALCD
• 2 x 5 m solar connection cables 4mm²
• MC4 connector set (socket + plug) already pre-assembled
• 1.5 m battery connection cable 4mm² incl. 20 A blade fuse
• Operating instructions for all devices in German

One set - many applications

These kits are the perfect foundation for your off-grid power supply and offer a solid basis for a wide range of applications. For example, they can power allotments, garden sheds, tiny houses, lighting systems, surveillance systems, self-sufficient measuring devices, small holiday homes, boathouses, or other stationary applications.

The convenient USB charging function allows for easy charging of mobile phones, tablets, or laptops. All devices with 5V (USB, max 2A) or 12V (controllable load output) can be charged quickly and easily off-grid.

Which charge controller is the right one?

Basically, one can distinguish between two charging technologies: PWM or MPPT.

Pulse-width modulation (PWM) is a simple and robust way to charge a solar battery safely and quickly. The stored characteristic curve protects the battery from incorrect currents or voltages; the controller implements the appropriate values ​​depending on the state of charge. The controllers in the LR-ALCD series are therefore a cost-effective yet reliable solution.

In recent years, the modern Maximum PowerPoint Track (MPPT) method has become increasingly prevalent.
Intelligent microprocessor electronics constantly determine the operating point for maximum energy efficiency. Even higher voltages are optimally utilized for charging. This allows WSL MPPT series controllers to generate up to 30% higher yields compared to traditional PWM devices.

It's possible to select a charge controller that's "oversized." This allows you to retrofit identical solar panels later. For example, if energy consumption increases or the system was initially undersized – no problem, simply install another panel, and the solar system will grow with your needs!

All controllers feature an integrated LCD display – system voltages and currents are shown in real time. This allows you to keep a constant eye on your power supply.
