Solar LCD Charge and Discharge Controller 10A-60A for 12V/24V Lead-Acid Batteries with PWM Charging and Self-Healing Protections

This solar controller ensures your lead-acid battery bank stays charged efficiently by automatically detecting 12V or 24V system voltages during initial setup, eliminating guesswork. Its large-screen LCD lets you monitor and adjust charge and discharge parameters directly, giving you control over your solar power system. Designed for reliability, it uses industrial-grade components and a dual MOS anti-backflow circuit to keep heat low and performance steady. Available in 10A, 20A, 30A, 50A, or 60A ratings, it fits a range of small to medium solar installations.

Features and Construction

The controller combines practical protection circuits with clear data display, making it suitable for off-grid cabins, RVs, or backup power systems. All protections reset automatically, so no manual intervention is needed after a fault clears.

Industrial-Grade Main Chip

The controller uses an industrial-grade master chip for consistent switching and voltage regulation, reducing the chance of failure under variable solar input conditions.

Large-Screen LCD Display

The LCD screen shows system status and allows you to adjust charge and discharge parameters without extra equipment, simplifying setup and monitoring.

Three-Stage PWM Charging

Complete three-stage PWM charging management optimises battery charging by delivering bulk, absorption, and float stages, prolonging battery life while preventing overcharging.

Protection and Safety

Built-in protections cover the most common wiring faults, and all are self-healing, so the controller resumes normal operation once the fault is removed.

Over-Current and Short-Circuit Protection

If current exceeds safe levels or a short circuit occurs, the controller disconnects automatically and resets when safe conditions return, preventing damage.

Open-Circuit Protection

Should the battery or solar panel become disconnected, the controller protects the system components from voltage spikes.

Reverse Connection Protection

If the battery or solar panel polarity is reversed, the controller protects itself and the connected equipment, with automatic recovery once corrected.

Uses and Placement

The controller is best used with photovoltaic panels only, installed close to the battery to minimise voltage drop from long cables. Place it on a flat, ventilated surface to dissipate heat during normal operation.

Off-Grid Solar Systems

Ideal for cabins, sheds, or remote installations where reliable battery charging from solar panels is needed, with adjustable parameters for different battery types.

RV and Marine Use

Compact and robust, this controller works well in mobile settings where space is limited and consistent charging is required for lead-acid house batteries.

Backup Power Systems

Use as part of a small backup solar setup to maintain batteries in standby mode, with PWM charging to prevent overcharging when grid power is available.

Benefits and Buying Value

This controller offers straightforward protection and monitoring without complex programming, making it suitable for DIY installers and professionals alike. Its self-healing features reduce the need for manual resets, saving time and hassle.

Reuse and Low Maintenance

The self-healing protection circuits mean the controller can automatically recover from most common faults, minimising downtime and maintenance visits.

Why Choose This Product

With adjustable LCD parameters, multi-stage PWM charging, and industrial-grade components, it provides reliable solar charge management at a practical price point for 12V/24V lead-acid systems.
