Main specifications Style: 30A Item type: Solar Controller Material: ABS Voltage: 12V, 24V automatic identification The Photovoltaic Voltage: Floating voltage: 13.7V (default, adjustable) Discharge cut off voltage: 10.7V (default, adjustable) Discharge recovery voltage: 12.6V (default, adjustable) USB output: 5V, 3A Standby current: Working temperature: 35 to +60 C Protection and performance highlights Three stage charging management for bulk, absorption, and float stages to balance fast charging and battery longevity. Comprehensive circuit protection reduces risk of damage from common faults and improves overall conversion efficiency. Recommended mounting on a flat, well ventilated surface because the controller will heat up during operation. Packing list 1 x Solar Controller 1 x User Manual Practical applications RV and caravan battery charging for lights, pumps, and accessories on trips. Small off grid cabins or sheds to maintain a 12V or 24V battery bank for lighting and low power loads. Boats, camping setups, and remote monitoring stations that need reliable USB device charging and automated battery management. Installation tips Mount on a flat, ventilated surface to allow heat dissipation. Confirm battery system voltage before connecting and use proper gauge wiring for the controller current rating. Use the LCD display to check and adjust floating, cutoff, and recovery voltages to match the battery chemistry and desired settings.
