- Surge protection: Shields connected devices from voltage spikes to prevent damage and downtime. - Overcurrent protection: Limits current to safe levels, protecting wiring and components and extending system life. - Overtemperature protection and real-time LCD display: Prevents overheating while the LCD dynamically shows operating data and the device status for easy monitoring. - User configurable controller parameters: Some settings can be changed, saved, and recalled to fit different applications without reconfiguration from scratch. - Light and Time Delay Control Mode: When the controller detects nights, it delays ten minutes, then start discharging and countdown. When the timer stops at zero, the discharge stops. The longest delay time is 23:59. Use scenarios - Solar garden lighting: After dusk, discharge begins following the delay to power lighting loads while protecting battery health. - Off-grid battery systems: Timed discharge management helps balance loads, improve reliability, and extend battery life. - Small backup power setups: Automatic night-time discharge control supports essential loads while preserving reserve capacity for critical events.
