About This

【Smart Wireless Controller】 20A PWM Solar Controller, enabling wireless smart monitoring via the LiMu Solar APP (initial password: 666666). It allows remote setting of 6 load modes (light control/timing/manual, etc.) and 5 battery types (lithium, gel, sealed lead-acid, etc.), improving operational convenience by 100% compared to traditional controllers.
【Precise Charging Management】 Utilizes intelligent PWM three-stage charging technology, automatically identifying 12V/24V systems. Maximum solar voltage: 50V, with charging voltage accuracy of ±0.5% (lithium 14.2V/28.4V, lead-acid 14.6V/29.2V). Equipped with temperature compensation (-4mV/°C/2V), charging efficiency reaches up to 98%.
【Industrial-Grade Safety Protection】 7 levels of protection: solar panel reverse connection/battery reverse connection/over-voltage (cut-off at 29.6V)/under-voltage (disconnection at 11.2V)/overload (cut-off at 160% load for 5 seconds)/short circuit/over-temperature (shutdown at 70°C), with IP30 dust and moisture-proof design.
【Dual Output Configuration】 20A main load output (supports segmented timing control) + 5V/1.5A USB interface (for mobile phone charging). The smart chip automatically manages the solar panel and battery system, suitable for off-grid lighting, RV power supply, and other scenarios.
【Convenient Installation Design】 Compact body size of 115x95x30mm, with three-color LED status indicator. Standard wiring sequence: battery → solar panel → load, allowing for quick deployment in just 3 minutes.
