- Industrial-grade main control chip for reliable, durable operation. - Large LCD display shows real-time data: charging and discharging currents; cumulative energy generation and consumption; temperature; ambient light control with delay function; adjustable charging and discharging parameters; power-off memory. - Dual USB output up to 2.5 A for simultaneous device charging. - Complete three-stage charging management for optimized performance and battery health. What it solves and why it helps - Easy energy monitoring: instantly see how your system is charging, discharging, and how much energy has been generated or used. - Flexible control: adjust charging and discharging parameters to fit different battery chemistries and usage patterns. - Safe and convenient: power-off memory restores the last state after power loss; dual USB outputs support multiple devices at once. Applications and scenarios - Off-grid solar or battery storage: track energy flow, optimize charging actions, and rely on memory to resume settings after outages. - Portable or vehicle power management: charge phones and devices via USB while monitoring current and temperature, with built-in light control and delay options. - Home backup or smart devices: manage charging cycles and observe energy generation/consumption for better household energy planning.
