The 30A Digital PWM Solar Charge Controller with LCD and USB Output Port regulate current from a solar panel into a battery by switching the charge connection on and off rapidly as the battery approaches full voltage. That pulse-width modulation reduces charge current smoothly rather than cutting it abruptly, extending battery cycle life compared to simple on/off regulation. The digital pwm solar charge controller handles up to 30 amps of charge current – enough for approximately 360W of solar panels on a 12V system or 720W on 24V – and auto-detects which battery voltage is connected without jumpers or menu navigation.
The LCD display shows battery voltage, charge current, load current, and system status in real time. That live data removes the guesswork that simple LED indicators leave behind, letting the operator confirm the system is charging correctly without connecting a separate meter. The 3A USB output at 5V delivers enough current to fast-charge a phone or power a small IoT monitoring device directly from the solar system without a separate inverter.
Solar input stays below 50V, covering standard 12V and 24V panel open-circuit voltages safely within the controller’s input range. The pwm solar charge controller operating temperature from -35°C to 60°C suits rooftop, outdoor shed, and vehicle roof installations across climate conditions year-round. The 30A solar controller suits medium-sized off-grid systems where the 20A variant no longer provides sufficient headroom. Available on StemVolt.
