10A Solar Charge Controller for 12V and 24V Systems Key benefits Automatic system detection: Automatically adapts between 12V and 24V systems for simple setup and reliable charging. Protected and reliable charging: Builtin protections for overcurrent, short circuit, reverse connection, low voltage and overcharge help protect panels, batteries and loads. Battery care with PWM charging: Threestage PWM charging (bulk, boost and float) helps maintain battery health and extend service life. Convenient USB output: 5V 2A USB port for charging phones, tablets and other small devices directly from the controller. Wide operating range: Designed to work in harsh conditions from 35 C to +60 C. Specifications Size / Rating: 10A controller System voltage: 12V / 24V automatic adaptation (battery voltage settings adjustable between 11.1V and 12.8V) Maximum photovoltaic input voltage: 25V for 12V systems, 50V for 24V systems USB output: 5V 2A maximum Control type: Industrial microcontroller with PWM regulation Operating temperature: 35 C to +60 C What it does and why you need it Manages solar panel charging and load output for small offgrid systems where reliable battery charging and device charging are required. Prevents common faults such as reverse wiring, short circuits and overcharging, reducing risk to batteries and connected equipment. Provides a convenient USB power source so small devices can be charged without separate adapters. Installation and use Connect in this for safe startup: battery first, solar panel second, then load. For wiring, loosen the terminal screw, insert the conductor into the terminal hole and tighten the screw to secure the wire. Verify system voltage selection and battery voltage setting as needed before regular use. Typical applications Small cabin or RV electrical systems for lighting, battery charging and device charging. Garden, pathway or remote lighting powered by a small solar array and battery. Portable or emergency charging station to keep phones and small electronics powered during power outages. Package contents 1 x Solar Controller (10A) 1 x English User Manual Notes and limitations This controller is designed to be charged only by photovoltaic solar panels. Do not use DC power supplies or other nonphotovoltaic sources as the charging input. Check panel open circuit voltage against the maximum photovoltaic input voltage for your system to avoid damaging the controller.
