30A LCD PWM Solar Charge Controller with Timer and Dual USB Ports (12V/24V Auto)

Meet a dependable, cost‑effective solution for off‑grid power: the 30A LCD PWM Solar Charge Controller designed for lead‑acid battery systems. With automatic 12V/24V detection, built‑in timer, and a clear LCD readout, this regulator puts precise charging and reliable protection at your fingertips—without the complexity of more advanced controllers.

Smart, user‑friendly charging you can trust

• 30A charge current and 30A discharge capability to handle typical rural or small‑scale solar setups with heavy daily cycles.
• LCD display for real‑time voltage, status icons, and quick system checks—no guesswork.
• Built‑in timer to automate charging schedules, helping optimize battery life even when you’re away from the system.
• Dual USB ports provide convenient mobile device charging directly from your solar setup.
• Temperature compensation tailored to your environment, helping preserve battery health across temperatures.
• Dual MOSFET reverse current protection minimizes self‑discharge at night, preserving every watt.

Reliability you can count on in challenging conditions

• Proven protection suite: overcharge, overdischarge, short‑circuit, and polarity safeguards keep both panel and battery protected.
• Moisture‑tight coating and a built‑in electronic fuse reduce maintenance needs and shield electronics from humidity and pests.
• Low heat production and high‑reliability design focus on long‑term operation in remote or rural environments.
• Compact, durable enclosure designed for wall or panel mounting in harsh outdoor or shed settings.

Compatibility, limits, and what you can power

• Battery compatibility: specifically designed for lead‑acid batteries (OPEN, AGM, GEL) — not suitable for NiMH, lithium‑ion, or other chemistries.
• PV input: up to 50V with a maximum PV input power of 390W at 12V or 780W at 24V.
• Operating range: reliable performance from −35°C to +60°C, making it suitable for a wide range of climates.
• Self‑consume: ≤10mA, so it won’t drain your battery when idle.
• Weight: lightweight design at around 150g for flexible mounting in compact installations.

Ideal uses and practical installations

Perfect for small off‑grid homes, remote cabins, village electrification projects, CCTV or cell‑site backups, and emergency power kits. The “set‑and‑forget” nature of this controller, combined with its adjustable parameters accessible via the LCD, makes it easy to tailor charging to your battery type and panel configuration without technical complexity.
