CMTP02 5A PWM Solar Charge Controller 12V 24V Overview A compact PWM charge controller designed to manage charging between a solar panel and a battery in small 12V or 24V systems. Model CMTP02 provides basic automatic voltage recognition and a steady charging current up to 5A for small off grid and auxiliary power applications. Key benefits Reliable charge regulation: PWM charging helps control charging voltage and current to reduce the risk of overcharging and maintain a stable charging process. Automatic system recognition: Automatically detects and configures for 12V or 24V battery systems, eliminating manual setup errors. Simple integration: Intended for small solar setups where ease of installation and straightforward wiring are priorities. Compact and space efficient: Small footprint that fits into limited mounting locations and DIY enclosures. What this product solves Prevents uncontrolled charging from a solar panel to a battery in small systems. Removes the need to manually select system voltage when switching between 12V and 24V setups. Provides a simple, lowcost solution for managing charging current in systems that draw up to 5A. Key attributes Model: CMTP02 Charging method: PWM Rated current: 5A Supported system voltages: 12V and 24V automatic recognition Function: Solar panel charge regulation to battery Compatibility and use limits Designed for small solar panels and battery systems where the charging current does not exceed 5A. Compatible with common 12V and 24V battery systems used in small off grid applications. Confirm battery type and system requirements before installation. Practical applications Small garden or pathway solar lighting systems where a dedicated controller is needed to regulate charging. Auxiliary battery maintenance on RVs, boats, or trailers using a small rooftop or portable solar panel. DIY cabin, remote sensor, or hobby solar kits that require a basic charge controller for a single battery bank. Installation notes Connect solar panel, battery, and load according to standard wiring practices for PWM controllers. Verify polarity and system voltage before applying power. Ensure the total charging current from the solar panel does not exceed 5A. What to expect A straightforward PWM charge controller in model CMTP02 form that offers automatic 12V/24V switching and up to 5A charging control for compact solar installations and auxiliary power setups.
