Usage Tips:Experience next-level functionality with our Enhanced 30A PWM Solar Charge Controller. Capable of automatic detection between 12V and 24V systems, this device supports up to 750W on 12V and 1500W on 24V systems. Our versatile solar charge controller is compatible with all 12V & 24V &36V&48V batteries and features a CUS mode for custom parameter settings. Easily switch between preset types: (lithium ferrophosphate), FLD (flooded), SLD (sealed lead acid), GEL (gel type), ensuring broad application suitability. Precision is critical, and our advanced controller excels with latest upgrades ensuring measurement accuracy within 1% error. The clear LCD display, alongside ly added buttons, enhances user interaction, allowing for fluid navigation and adjustments. Incorporating intelligence in energy management, our three-stage PWM (Pulse Width Modulation) charging (bulk, absorber, float) maximizes efficiency. Various protections-including reverse polarity, short circuit, overcurrent, and thermal safeguards-help extend battery life and improve overall safety. Built to withstand the demands of outdoor environments, our controller features a metal plate for optimal heat dissipation. perfect for RVs, camping, and marine applications, it ensures reliable performance in weather conditions.
