BougeRV Sunflow 30A MPPT Solar Charge Controller 12V/24V — Bluetooth APP, Low-Temp Cut-Off

BougeRV Sunflow 30A MPPT is a 12V/24V solar charge controller that delivers high-efficiency MPPT charging, app and LCD control, and low-temperature cut-off protection for LiFePO4 and other battery types.

Designed for RVs, boats, off-grid cabins and mobile power setups, the BougeRV Sunflow 30A combines MPPT tracking with smart controls to maximize solar harvest while protecting batteries. It supports 12V and 24V systems, up to 30A charging current, and works with LiFePO4, SLA (AGM, GEL), and other lead-acid chemistries. Built-in safeguards and a compact heat sink keep the unit reliable in everyday use, while Bluetooth APP access and a backlit LCD let you monitor and tweak settings without tools.

How does the Sunflow 30A improve solar charging performance?

The controller uses MPPT (Maximum Power Point Tracking) to continuously find the optimal operating point of your solar array so panels deliver more usable energy than a basic PWM regulator. BougeRV reports tracking efficiency up to 99.5% and peak conversion efficiency near 99% to reduce wasted input and speed battery recharge.

• Adjustable charging current from 0A to 30A to match battery capacity and load.
• Max PV input power: 450W at 12V, 900W at 24V for substantial array support.
• High-voltage input tolerance up to 95V for flexible panel configurations.

What battery protections and compatibility does it offer?

Sunflow supports LiFePO4 and multiple lead-acid types with a low-temperature cut-off that prevents charging below 32°F (0°C) for LiFePO4 cells. The unit includes a suite of electronic protections to guard batteries and connected equipment from common faults.

• Low-temp cut-off and restart for LiFePO4 to avoid charging at unsafe temperatures.
• Protections for over-temperature, over-current, short-circuit, reverse polarity, open-circuit and reverse current.
• Dual MOS circuit design reduces heat and prevents reverse flow into panels overnight.

How do I monitor and control the controller—locally or remotely?

BougeRV equips the Sunflow with a backlit LCD and physical buttons for local setup and a mobile APP for remote monitoring within about 32 feet. Choose full-featured display mode to adjust parameters without the app, or connect via Bluetooth for a more convenient readout of solar, battery and load status.

• Three display modes: full-featured, no-load, and viewing-only for flexible local control.
• Bluetooth APP control provides remote status and setting access up to ~32 feet.
• Screen wakes and recognizes battery when battery is connected first—follow the wiring order for proper start-up.

What installation and technical limits should I know about?

The Sunflow is sized for small- to medium off-grid systems and requires correct wiring sequence and appropriate cable gauges. It is CE and RoHS certified and comes with dedicated tech support if you need setup help.

• System voltages: 12V/24V auto-recognized; wire size recommended 15–8 AWG.
• Rated charging current: up to 30A; rated load current listed at 20A for load output usage.
• Max PV input voltage: 95V; ensure panel Voc stays below this limit.

Who is this for: The BougeRV Sunflow 30A MPPT controller is aimed at RV and marine owners, tiny-home and cabin users, and anyone running small off-grid systems who needs reliable MPPT performance, LiFePO4-safe features, and convenient Bluetooth or local LCD control. It’s a practical upgrade for users who want more solar harvest, smarter battery protection, and straightforward setup without bulky hardware.
