Redodo MPPT Solar Charge Controller 24V 40A Bluetooth — 100V PV Input, 99% Tracking, RS485

Redodo 24V 40A (Bluetooth) MPPT Solar Charge Controller is a compact, high-efficiency regulator that maximizes PV harvest with 99% tracking and remote monitoring via built-in Bluetooth.

This MPPT controller is engineered for small to medium off-grid and backup solar systems where efficiency, monitoring and safety matter. It supports 12V/24V battery banks, accepts PV inputs up to 100V, and delivers up to 40A charging current while offering multiple battery profiles and robust protection features. The aluminum alloy casing helps dissipate heat and keeps the unit reliable under continuous use.

How does it improve solar charging efficiency?

The controller uses maximum power point tracking (MPPT) algorithms to follow the solar array’s optimal operating point so the batteries receive the most power available. With tracking efficiency up to 99% and peak conversion close to 98%, it reduces energy loss compared with PWM controllers.

• MPPT algorithm that searches maximum power point continuously
• Tracking efficiency rated up to 99% for better yield
• Peak conversion efficiency about 98% to minimize losses
• Accepts high PV voltage (up to 100V) for larger panel strings

Can I monitor and adjust settings remotely?

Yes — the unit includes a built-in Bluetooth module for real-time monitoring and setup from a smartphone. For wired communication or networked systems, it supports RS485 via the included RJ12 cable, allowing integration with compatible management tools.

• Built-in Bluetooth for local wireless monitoring and configuration
• RJ12 port with RS485 support for wired data networks
• On-unit LCD and LEDs give immediate status and error indications
• Four front buttons enable manual configuration without external devices

Which battery types and voltages does this controller support?

The Redodo controller automatically supports 12V and 24V systems and ships with a LiFePO4 charging profile by default. You can change settings to accommodate lead-acid varieties such as flooded, sealed and gel types, tailoring charge parameters to the battery chemistry in use.

• Auto-detect/selection for 12V or 24V battery banks
• Default LiFePO4 charge mode with adjustable parameters
• Selectable profiles for flooded, sealed, and gel lead-acid batteries
• Adjustable charge voltages, float levels and charge current limits

What safety and build features protect my solar setup?

The controller is housed in an aluminum alloy shell designed for thermal transfer and long-term durability. It incorporates multiple electrical protections to shield panels, batteries and loads from common faults and harsh conditions.

• Aluminum alloy enclosure for improved heat dissipation
• Reverse-polarity and short-circuit safeguards to prevent damage
• Overvoltage, overpower and over-temperature shutdown features
• Durable connectors and clear terminal labeling for safe wiring

Who is this for: Installers, vanlifers, cabin owners and small off-grid system builders who need a reliable, feature-rich MPPT controller that balances high conversion efficiency with flexible monitoring. Choose this model if you want a 40A charging capacity, Bluetooth monitoring and support for multiple battery chemistries while keeping PV string voltage options up to 100V.
