Features
- 【30A Solar Charge Controller】The Anern PWM solar controller utilizes full 3-stage PWM charge management to improve system efficiency. It performs direct, boost, and float charging through PWM regulation, enabling efficient, fast, and intelligent charging that effectively extends battery life.
- 【Multiple protection】This solar panel controller features built-in overcurrent/overload protection, open circuit protection, and reverse polarity protection. All protections are self-recovering and will not damage the unit, ensuring safe application for home, industry, and more.
- 【Functional LCD Display】Easy to install and operate, the intuitive LCD clearly displays status and data. This solar controller 12v allows mode switching and parameter configuration, with adjustable cut-off levels to perfectly protect batteries from over-discharge, suitable for home, industry, and commerce.
- 【Battery Type】This solar charge controller 12v is suitable for lead-acid batteries (OPEN, AGM, GEL) and is not for nickel-metal hydride, lithium, or other types. Its built-in industrial microcontroller automatically controls the charging between solar panel and battery.
- 【Widely Used】This outdoor charge controller with dual USB ports is compatible with 12V/24V systems. The 5V/2A USB port supports charging phones or other 5V devices, protects batteries from overcharging/discharging, and is suitable for home, industry, and business.
