Solar Charge Controller 20A 12V/24V
The SLD TECH NR Series Solar Charge Controller is a 20A PWM controller designed to manage solar charging for 12V and 24V battery systems, with automatic system voltage detection. It uses vivid LED indicators to show battery capacity status and load state at a glance, making it easy to monitor your off-grid power setup.
PWM charging increases charging efficiency by 3%-6% compared with non-PWM charging, while automatic charge/discharge parameters help keep your battery healthy. Built-in protection guards against over-charge, overload, over-discharge, and reverse connection, providing reliable operation for gate, access-control, and other remote solar-powered installations.
An integrated USB output (5V/1A) lets you charge a cell phone or other small device directly from the controller, and an On/Off power button gives you simple manual control over the load.
