Product name: Solar controller Color: blue Material: plastic Size: 20 x 20 x 7 cm Available charging current models: 60A, 80A, 100A Battery voltage: automatic identification of 12V, 24V, 36V, 48V Key benefits efficiency MPPT tracking increases energy harvest from solar panels with tracking efficiency exceeding 99.5 percent, improving charge speed and system performance. Clear LCD screen shows realtime operating data and status for easier monitoring and system adjustments. Broad battery compatibility supports Seal, GEL, Flood, and LifePO4 battery types, simplifying integration into existing systems. Builtin protections for overvoltage, overcurrent, and temperature help protect connected batteries and equipment. Dual USB 5V ports allow convenient charging of phones and small devices directly from the controller. Automatic system voltage detection and selectable working modes provide flexible control for lighting, timing, and continuous discharge applications. Compact plastic housing and straightforward wiring make installation in offgrid and mobile setups practical. Main features MPPT max power point tracking technology with tracking efficiency exceeding 99.5 percent. LCD display for dynamic presentation of operating parameters and device status. Compatible with Seal, GEL, Flood, and LifePO4 battery chemistries. Dual USB 5V charging ports for external device charging. Automatic identification of 12V, 24V, 36V, and 48V systems. Protections include overvoltage protection, overcurrent protection, and temperature protection. Seven selectable working modes for flexible system control. Selectable working modes 1. No discharge: Charging only, discharge is disabled under all conditions. 2. Light control: Controller starts discharge after a 10minute delay when night is detected, and stops discharge 10 minutes after daylight is detected. 3. Light with delay timer: On night detection the controller waits 10 minutes then begins discharge and counts down a userset timer. Maximum delay timer is 23 hours 59 minutes. 4. Always on: Continuous discharge without interruption. 5. Manual control: User starts or stops discharge manually using the controller controls. 6. Timed on/off: Discharge opens and closes according to a programmed schedule. 7. Test mode: Similar to light with delay timer but with a fixed 10minute delay for testing. Lowvoltage override note The controller can continue discharging even when lowvoltage protection is triggered. Press and hold the discharge control for five seconds to resume discharge output. This override must be used with caution because it can damage the battery if the battery remains at low voltage.
