Product Details 🏷️

The Renogy Wanderer-Li is a 30A PWM solar charge controller that incorporates efficient PWM crediting boost battery life and improving system performance.

30A PWM Solar Charge Controller (RS-PWM30P) – Auto 12V/24V detection, supports sealed/GEL/flooded/lithium batteries. Features 3-stage PWM charging, temp compensation, and equalization. 450W (12V)/900W (24V) power, 55V input, IP30 rated.

ECO-WORTHY upgraded 30A PWM Solar Charge Controller with improved internal components. Automatically detects 12V/24V DC system voltage, maximum discharge current of 30A, supporting a maximum system power of 12V 750W; 24V 1500W. Built-in dual USB outputs 5V/2A for charging your devices on–go.

It also protects your battery from being overcharged by the solar panel, or over-discharged through the DC loads connected to terminals 5-6 (if any). The unit uses PWM (Pulse Width Modulation) current control techniques to regulate the charging current (and so the voltage) being supplied to the battery by the panel (or panels).
