ECO-WORTHY 20A MPPT Solar Charge Controller 12V/24V with Bluetooth, LCD & Multi-Battery Support

The ECO-WORTHY 20A MPPT Solar Charge Controller is a compact, Bluetooth-enabled regulator that optimizes solar panel output for 12V or 24V battery systems while providing multi-level safety protections.

This MPPT (Maximum Power Point Tracking) controller from ECO-WORTHY combines high tracking efficiency with wireless monitoring and adjustable charging profiles. It automatically detects 12V or 24V battery banks, supports common battery chemistries including GEL, SLA, FLD and LFP, and includes features to protect and extend battery life. The built-in Bluetooth and clear LCD simplify setup and day-to-day oversight without extra hardware.

How does the MPPT improve solar energy harvest?

This controller continuously finds the optimal operating point for your solar array so panels produce near-maximum power. Compared with simpler PWM regulators, MPPT can convert more panel output into usable charge current under varying sunlight and temperature.

• Tracking efficiency ≥ 99% for sustained power optimization.
• Peak conversion efficiency ≥ 99% to reduce energy loss.
• Low self-consumption so the controller uses minimal power when idle.
• Automatic 12V/24V detection for easy integration with typical battery banks.

What battery types and charging modes are supported?

The unit supports GEL, SLA, FLD and lithium (LFP) batteries and allows activation of lithium-specific safeguards. Charging follows a three-stage algorithm to balance fast replenishment with battery longevity.

• Automatic battery voltage recognition (12V/24V) for plug-and-play use.
• Three-stage charging: bulk, absorption/balanced, and float stages.
• External temperature sensor included to adapt charging to thermal conditions.
• Configurable settings through the app or on-device controls for custom battery profiles.

Can I monitor and configure the controller remotely?

Yes — the built-in Bluetooth eliminates the need for an additional communication module. Pair the controller with the ECO-WORTHY app to view real-time data, adjust parameters, and review fault alerts from your smartphone.

• Integrated Bluetooth for wireless monitoring via mobile app.
• High-resolution LCD displays system status, voltages, currents and error codes.
• Remote parameter setup saves trips to the installation site.
• App-based logging helps track performance trends over time.

What safety and installation features should I expect?

The controller includes multiple protections and a straightforward mounting design to ensure safe, reliable operation. Terminals are covered for shipping and must be uncovered before wiring; installation typically takes minutes for a standard small system.

• Protections for over-voltage, over-charge, over-discharge, over-temperature and short circuits.
• Terminal protective cover—remove before connecting wires for safety.
• Durable buttons and firm terminals for reliable connections and easy operation.
• Quick 5-minute installation for most DIY and professional setups.

Who is this for: The ECO-WORTHY 20A MPPT controller is intended for homeowners, RV and boat owners, small off-grid cabins, and anyone running modest solar arrays who wants better power conversion, Bluetooth convenience, and comprehensive battery protection. It fits systems using 12V or 24V battery banks and is especially useful where monitoring from a phone or quick setup is desired.

Package contents include the 20A MPPT controller, a 1.5m temperature sensor, mounting screws and anchors, plus an English instruction manual for a complete out-of-box installation.
