60A12V-V125. For 12V lithium and lead-acid batteries, it uses intelligent BMS power failure protection. When the BMS is suddenly disconnected, it starts an intelligent shunt of photovoltaic voltage in milliseconds, completely avoiding over-voltage risk for lithium batteries. The protection level is comparable to industrial-grade energy storage equipment, eliminating potential battery damage. Zero power off-grid emergency start. First PV direct-drive emergency mode: even if the battery is completely depleted, it can dynamically capture light energy through an AI algorithm to start the system directly. This breaks dependence on battery power and increases reliability of power supply in field or disaster scenarios by 200%. Adaptive battery calibration system. Includes battery charging voltage calibration function and supports expansion of a cloud WiFi module (cloud box required) to enable APP/web remote monitoring of charging and discharging status, remote parameter setup, and real-time monitoring data. LCD Display. High-resolution backlit LCD shows cumulative power generation (±0.5%), charging voltage (±0.1V), fault codes and key operating parameters in real time, visible in low light conditions, and supports dual-parameter definition mode.
