Solar Controller 20A PWM-Charge Controller SCPWM20

Product Overview

The SCPWM20 is a generic model for a 20A Pulse Width Modulation (PWM) solar charge controller. It manages the flow of power from solar panels to efficiently charge batteries in smaller off-grid solar systems, such as for RVs, boats, or garden sheds. It is designed to work with either 12V or 24V battery systems.

Key Features

• Automatic system detection: Automatically detects and adjusts for either a 12V or 24V system.
• Battery compatibility: Works with common lead-acid batteries like Sealed, Gel, and Flooded. Some variants may also support lithium batteries, but this is not a universal feature, PWM charging: Uses PWM technology to perform a multi-stage charging process, which helps prevent battery sulfation and extends the battery's lifespan. Display and interface: An integrated LCD screen is common, displaying system information like battery voltage and charging current.
