MPPT Solar Charge Controller 60-100A with Dual USB

Smart MPPT Solar Charge Controller for Lead Acid & Lithium Systems

- Manage your off‑grid power reliably with this advanced MPPT solar charge controller, designed for 12V, 24V, 36V and 48V battery banks. Ideal for RVs, cabins, boats, telecom sites and small home systems, it optimises panel output while protecting your batteries and connected devices.

This controller uses high‑efficiency MPPT (Maximum Power Point Tracking) technology with tracking efficiency up to 99.5%, helping you extract more usable power from your solar array in changing light conditions. It supports a wide range of battery types including Sealed, GEL, Flooded and LiFePO4, with automatic voltage identification for 12V/24V/36V/48V systems. Maximum PV input power is up to 720W (12V), 1440W (24V), 2160W (36V) and 2880W (48V), with a maximum solar input (Voc) range of 15-25V (12V), 30-50V (24V), 45-75V (36V) and 60-100V (48V). Charging current is 60-100A, providing strong support for medium to larger off‑grid installations.

The integrated LCD with backlight clearly displays key operating data in real time, including working mode, battery voltage, PV charging current, battery discharge current, controller temperature and delay time. Seven selectable working modes allow precise control of load output: charging‑only mode, light control mode, light + time‑delay mode, universal (always‑on) mode, manual control mode, timing control mode and test mode for quick setup checks. Dual 5V USB ports on the front panel let you charge phones, tablets and other small electronics directly from your solar system without an additional adapter.

Built‑in electronic protections include over‑voltage, over‑current and over‑temperature protection, helping safeguard both your batteries and connected loads. Some parameters are user‑configurable and can be saved, allowing you to fine‑tune the controller to your specific battery chemistry and application, such as solar street lighting, courtyard lighting, traffic systems or remote communication power.

FAQ

Q: Which battery types are compatible with this controller?
A: It supports Sealed, GEL, Flooded and LiFePO4 batteries across 12V, 24V, 36V and 48V configurations. Always set the correct battery type and follow the battery manufacturer's charging recommendations.

Q: Can I use this controller for solar street lights or courtyard lights?
A: Yes. The light control and light + time‑delay modes are designed for lighting applications, allowing the load to turn on automatically at night and switch off after a set duration.

Q: What is the maximum solar panel power I can connect?
A: The maximum PV input power is approximately 720W for 12V systems, 1440W for 24V, 2160W for 36V and 2880W for 48V systems, provided the open‑circuit voltage (Voc) of the array stays within the specified range for each battery voltage.

Q: Does the controller show real‑time system information?
A: Yes. The backlit LCD displays working mode, battery voltage, PV charge current, load discharge current, controller temperature and delay time, giving you clear visibility of system status.
