Description
The Duo Racer Series (10-30A) Dual Battery MPPT Charge Controller is a high-performance solar controller engineered for mobile and off-grid solar power systems. Using advanced MPPT (Maximum Power Point Tracking) technology, it optimizes solar panel output to deliver higher charging efficiency compared to traditional controllers.
This intelligent controller is specifically designed for dual battery systems commonly used in motorhomes, RVs, campers, boats, and caravans. It efficiently charges the main service battery (BATT1) used for appliances and lighting while simultaneously providing automatic trickle charging (up to 1A) to the vehicle start battery (BATT2). This ensures that both batteries remain healthy and ready for use.
The Duo Racer Series also includes multiple safety protections such as over-charge protection, reverse polarity protection, short-circuit protection, and temperature compensation, helping extend battery life and system reliability.
Usage Suggestions
Ideal for mobile solar systems, recreational vehicles, marine solar setups, and other off-grid energy applications.
Storage Instructions
Store the controller in a dry, dust-free environment and avoid exposure to excessive heat or moisture when not installed.
