Its large LCD screen gives you clear, adjustable control over charging and discharging parameters, helping you keep your battery within its safe voltage range. Built with an industrial-grade master chip and robust PWM charging management, it protects your battery from overcharging, deep discharge, and short circuits. The controller includes over-current, short-circuit, open-circuit, and reverse connection protection, all self-healing so the device remains undamaged after a fault. Available in five current ratings from 10A to 60A, it is designed specifically for photovoltaic solar panels and lead-acid batteries.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Solar LCD charge and discharge controller with large screen and PWM charging for lead-acid batteries\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/3534\/2025-10-16\/original-image\/1958404506520.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe controller uses proven industrial electronics and a smart charging algorithm to manage power flow efficiently. Its dual MOS anti-backflow circuit reduces heat generation and prevents battery discharge at night.\u003c\/p\u003e\u003ch3\u003eIndustrial-Grade Master Chip\u003c\/h3\u003e\u003cp\u003eThe controller is built around an industrial-grade master chip that ensures stable operation under varying solar and load conditions. This chip manages the PWM charging stages and monitors system parameters continuously.\u003c\/p\u003e\u003ch3\u003eLarge-Screen LCD Display\u003c\/h3\u003e\u003cp\u003eThe LCD screen shows real-time battery voltage, charging current, and system status. You can adjust the charge and discharge parameters directly via buttons on the controller, giving you manual control when needed.\u003c\/p\u003e\u003ch3\u003eComplete 3-Stage PWM Charging\u003c\/h3\u003e\u003cp\u003eThe controller uses a three-stage PWM charging algorithm: bulk, absorption, and float. This cycles the battery through fast charging to high voltage, then holds it at a safe level, and finally maintains a trickle charge to prevent overcharging and sulfation.\u003c\/p\u003e\u003ch2\u003eProtection and Safety\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Solar LCD charge and discharge controller with large screen and PWM charging for lead-acid batteries\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/3534\/2025-10-16\/original-image\/2054585858850.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe controller includes multiple self-healing protection circuits that guard against common installation and operating errors. These protections automatically reset once the fault clears, so no replacement or manual reset is required.\u003c\/p\u003e\u003ch3\u003eOver-Current and Short-Circuit Protection\u003c\/h3\u003e\u003cp\u003eIf the load draws too much current or a short circuit occurs, the controller instantly cuts power to protect both the battery and connected devices. Once the fault is removed, normal operation resumes automatically.\u003c\/p\u003e\u003ch3\u003eOpen-Circuit and Reverse Connection Protection\u003c\/h3\u003e\u003cp\u003eThe controller can handle open-circuit conditions on the solar panel side without damage. If the battery or solar panel is connected with reversed polarity, the controller protects itself and the connected components.\u003c\/p\u003e\u003ch3\u003eDual MOS Anti-Backflow Circuit\u003c\/h3\u003e\u003cp\u003eTwo MOS transistors in series prevent current from flowing back from the battery to the solar panel at night.
