Dual Battery PWM Solar Charge Controller for 12V/24V Systems

This dual battery solar charge controller is designed to manage solar charging for compatible 12V and 24V lead-acid battery systems. It supports two battery groups and can automatically switch the charging sequence once the first battery reaches the set charge level, helping keep both batteries managed in an organized way. The PWM charging system uses multiple charging stages to regulate the charging process for AGM, gel, flooded, sealed, and other compatible lead-acid batteries. The LED display allows users to monitor voltage and charge status, while the one-button setup makes adjustment simple for RVs, boats, small solar systems, backup power setups, and off-grid applications.
