Features and benefits Multiple protections: builtin protection functions enhance safety and reliability. When faults are cleared, the protections are selfrecovery types that do not damage the controller. Industrialgrade main control chip: industrialgrade control chip with 16level AD sampling accuracy. Provides temperature and charging current monitoring, accurate realtime display, and clear visibility of power generation at a glance. Autofocus MPPT tracking charging: delivers charging efficiency. Continuous detection during charging with twoway focus tracking for reliable MPPT performance. Color LCD display large screen: charging and discharging parameters are adjustable. The ultrawide charge and discharge range is adjustable. Use scenarios Offgrid solar or remote power systems: suitable for home, cabin, or small workshop setups where safe charging and realtime monitoring are important, thanks to MPPT tracking and comprehensive protections. DIY battery projects and portable power: supports multiple battery chemistries with adjustable charging parameters. Industrial or field applications: reliable selfrecovery protections and clear parameter display help manage battery charging and discharging in demanding environments.
