Made in Mainland China.

Key Features

• True MPPT Algorithm: Delivers up to 98.5% conversion efficiency, significantly outperforming conventional PWM charge controllers.
• 3 USB Outputs: Includes 1× USB-C fast-charging port plus 2 additional USB ports, enabling multiple devices to charge simultaneously directly from your solar system.
• Real-Time LCD Display: Monitors voltage, current, temperature, and charging/discharging status at a glance. On-device buttons allow easy mode switching and parameter configuration — no computer required.
• LED Indicator Lights: Instant visual status feedback for charging, discharging, and fault conditions.
• Ergonomic Industrial Design: Streamlined blue ABS engineering plastic shell with layered button and USB port placement following a thumb-accessible layout. Side-mounted flip-top wiring compartment and bottom ventilation slots create an efficient three-dimensional heat dissipation channel.
• Premium Materials:
  • Main shell: Flame-retardant, fire-resistant PC+ABS composite (rated -40°C to +85°C) with anti-UV coating to prevent aging and discoloration.
  • Circuit board: FR-4 epoxy glass fiber substrate for excellent damp-heat and electromagnetic interference resistance.
  • Heat dissipation fins: Anodized aluminum alloy — rust-proof, wear-resistant, with anti-loosening nut structure for safe, reliable high-current connections.
• Versatile Installation: Compatible with wall mounting, floor mounting, and recessed mounting configurations.
• Wide Application: Ideal for residential solar systems, RV and camper van builds, off-grid cabins, and outdoor camping setups.

Frequently Asked Questions

Q: What is an MPPT solar charge controller and how does it differ from a PWM controller?

A: An MPPT (Maximum Power Point Tracking) solar charge controller continuously adjusts its input to harvest the maximum available power from your solar panels, achieving up to 98.5% conversion efficiency. A traditional PWM (Pulse Width Modulation) controller is simpler and less efficient — MPPT technology typically delivers 20%+ more usable energy, especially in variable light conditions.

Q: What types of solar systems is this controller compatible with?

A: This MPPT solar charge controller is designed for home solar systems, RV and camper van setups, off-grid cabins, and outdoor camping applications. Its versatile installation options (wall, floor, and recessed mounting) make it suitable for a wide range of configurations.

Q: Can I charge USB devices directly from this solar charge controller?

A: Yes! This controller features 3 built-in USB ports, including 1× USB-C fast-charging port, allowing you to power smartphones, tablets, and other USB devices directly from your solar system without a separate inverter.

Q: Do I need a computer or special software to configure the settings?

A: No. All parameter configuration and mode switching can be done directly on the unit using the on-device buttons and the built-in LCD screen. No computer or external software is required.

Q: What does the LCD screen display?

A: The LCD screen provides real-time monitoring of voltage, current, temperature, and charging/discharging status, giving you complete visibility into your solar system's performance at all times.
