CMP12 10A Solar Charge Controller A compact 10A solar charge controller designed to regulate charging from solar panels to 12V or 24V battery systems with automatic voltage detection. The CMP12 provides safe charging, basic system protection, and simple installation for small off grid and auxiliary power setups. Key benefits Reliable battery regulation: Limits charge current to a maximum of 10A to prevent overcharging and reduce battery stress. Automatic voltage selection: Detects and switches between 12V and 24V systems without manual configuration. Built for simplicity: Straightforward wiring and compact form factor make it suitable for quick installation and tight spaces. Basic safety features: Integrated protection helps guard against common faults that can damage batteries and wiring. Main features and attributes Function: Regulates solar panel charging to battery, maintaining proper charge control and preventing battery overcharge. Compatibility: Works with 12V and 24V lead acid and other common battery systems when wired to the correct nominal voltage. Suitable for small solar panels and battery banks up to the rated current. Rated performance: 10A continuous charging current capacity. Model designation CMP12 (10 Amp). Construction: Compact, robust housing designed for mounting in small enclosures or on flat surfaces. Connects to solar panel, battery, and load via clear terminal points. User experience: Minimal setup required thanks to automatic voltage detection and simple wiring layout. Why customers choose this controller Protects battery investment by controlling charge current and avoiding excessive charging. Simplifies setup for small systems by removing the need to manually set system voltage. Saves space and reduces complexity in small installations where a fullfeatured MPPT or PWM controller is not required. Practical applications Small cabin or shed lighting: Regulate a single battery bank charged by a modest solar panel array to power LED lighting and small loads. RV or campervan auxiliary power: Maintain a 12V or 24V house battery from a rooftop solar panel while parked or boondocking. Mobile or marine electronics: Provide basic charge management for 12V or 24V batteries used for navigation lights, instrumentation, or auxiliary accessories. Quick specifications Model: CMP12 (10 Amp) Rated current: 10A System voltage: Automatic 12V or 24V selection Primary function: Solar charge regulation and basic protection Package note Controller only. Verify system voltage and wiring before connecting. Use appropriate wire gauge and fusing for the system current and installation environment.
