WATTSTUNDE® PWM Solar Charge Controller 20 A with LCD Display and USB Ports for 12 V / 24 V Systems

LR20ALCD Solar Charge Controller 20 A with LCD Display and Numerous Programmable Functions

The LR20ALCD is an intelligent solar charge controller featuring an LCD status display. The 20A solar charge controller reliably and gently charges the battery and protects it from dangerous deep discharge by automatically disconnecting its consumers using intelligent load shedding when the battery reaches a critical charge state. The 20A charge controller has also been designed to be very user-friendly, making all individually adjustable parameters very easy to set.
