Renogy Charge Controller-Rover 40A MPPT 12V/24V Auto-Detect LCD Display | 99.9% Efficiency for Gel/Flooded/Lithium Batteries | Dual-Peak Tracking & Modbus Support

Dual-Peak MPPT for Partial Shading & Cloudy Days: Maximize solar energy harvest with 99.9% multi-peak tracking efficiency, even if panels are partially shaded or damaged. Advanced algorithms ensure 98% conversion efficiency—20% higher than PWM controllers. Perfect for RV solar systems, off-grid cabins, or marine setups with fluctuating sunlight. Compatible with gel, sealed, flooded, and lithium batteries for versatile energy storage solutions.

Smart -40°F to 149°F Temp Control & TVS Lightning Guard: Automatically adjusts charging parameters for extreme weather durability, preventing overheating in deserts or freezing climates. Built-in TVS surge protection blocks lightning strikes, while reverse polarity/overload safeguards protect RV and marine batteries. Ideal for storm-prone areas and harsh outdoor environments.

4-Stage Charging + Lithium Battery Recovery Mode: Extend lead-acid battery life with Bulk/ Absorption/ Float /Equalization stages. Safely revive deeply discharged lithium batteries using 2-stage charging and lithium reactivation tech. Supports 12V/24V auto-detection for non-lithium systems and capacitive load surges (e.g., water pumps）

LCD Display & 1-Year Solar Performance Logging: Track real-time voltage, current, and error codes via the backlit LCD screen. Store 365-day data logs to analyze energy trends and optimize system efficiency. Integrates with Modbus protocol for smart home solar kits and remote monitoring software.

DC Load Control & Capacitive Surge Support: Directly connect DC appliances (fans, lights) to load terminals. Handles instant capacitive surges (pumps, motors) and offers timer scheduling for energy efficiency.

Bluetooth Monitoring with Renogy DC Home App: Pair with the BT-2 module (sold separately) to monitor solar performance via smartphone. Real-time alerts for battery faults, panel efficiency drops, and weather impacts. Perfect for mobile RV owners and remote solar farm managers.
