Bateria Power Sunrock 20Pro 20A MPPT Solar Charge Controller — 12V/24V, Bluetooth app monitoring

The Bateria Power Sunrock 20Pro is a 20-amp MPPT solar charge controller for 12V/24V systems that provides wireless phone-app monitoring, multi-chemistry battery support, and built-in safety protections.

This compact MPPT regulator is built to boost solar harvest and simplify system oversight. It automatically detects 12V or 24V systems, supports common battery chemistries (LiFePO4, AGM, Gel, Flooded, Sealed lead-acid), and pairs to a Bluetooth phone app for remote monitoring and custom charging profiles. The unit includes plug-and-play SAE connectors and two extension cables to speed installation and layout flexibility.

How does the Sunrock 20Pro increase charging efficiency?

The Sunrock 20Pro uses Maximum Power Point Tracking (MPPT) to extract more usable energy from panels than a simple PWM regulator. By continuously optimizing panel voltage and current, it reduces charging time and makes better use of available sunlight.

• MPPT tracking automatically follows optimum panel output for higher yield.
• Rated 20A continuous current, suitable for small off-grid or vehicle systems.
• Claims up to 20–30% faster charging versus non-MPPT controllers in many conditions.
• Automatic 12V/24V detection simplifies setup and prevents manual errors.

Which battery types and voltages are compatible with this controller?

This regulator is designed specifically for 12V and 24V battery banks and supports a variety of common chemistries. Choose the correct system voltage and battery type in the app or controller settings to ensure proper charge profiles and longevity.

• Supports LiFePO4, AGM, Gel, Flooded, Sealed lead-acid, and deep-cycle batteries.
• Do not connect batteries above 24V—unit is not rated for higher voltages.
• PV input must not exceed 60V; follow the recommended connection sequence: battery first, then panel.
• Customizable "USE Mode" in the app for advanced or unusual battery requirements.

What safety features and protections are included?

The Sunrock 20Pro integrates multiple hardware and software protections to guard both the battery and the controller. Intelligent three-stage charging and standard protective circuits reduce risk from common faults and stressors.

• Intelligent 3-stage charging: Equalize, Boost, Float for better battery maintenance.
• Protections include overcharge, over-temperature, over-voltage, over-current, and short-circuit.
• Reverse polarity and discharge protection to prevent wiring mistakes and battery drain.
• Built-in thermal management and monitoring via the phone app for safe operation.

How does the wireless phone app improve system control?

Bluetooth app connectivity gives on-site and remote access to real-time status and configurable charging parameters. The app allows monitoring of panel production, battery voltage, charging state, and lets installers save or restore custom settings.

• Real-time monitoring of panel output and battery condition via BT app.
• "USE Mode" enables custom charge parameters for specialty batteries or uses.
• Factory-settings recovery resets the controller if you need to undo DIY changes.
• Easy firmware updates and diagnostics through the app when available.

Who is this for? The Bateria Power Sunrock 20Pro is aimed at DIY off-grid enthusiasts, vanlife and RV owners, boaters, and small home or cabin system installers who need a compact MPPT controller with smartphone control. It suits anyone who wants improved harvest from their panels, flexible battery compatibility, and layered safety protections. Note: this unit is for 12V/24V setups only and requires that PV voltage stays below 60V; always connect the battery before attaching the solar array.
