1. USERFRIENDLY DESIGN: LCD displays are used to dynamically show operational data and device working status. Displays regulator parameters (working mode, battery voltage, photovoltaic charging current, battery discharge current, product operating temperature, delay time). 2. SAFETY VOLTAGE PROTECTION: MPPT solar controller with voltage protection, including battery overvoltage and overcurrent protection, power failure protection, overcharge protection, deep discharge protection, reverse polarity protection, and overheating temperature protection. 3. MULTIPLE BATTERY CHARGING OPTIONS: Compatible with charging GEL, Flooded, and lithium batteries. 4. MPPT TECHNOLOGY: 100A MPPT solar controller with advanced Maximum Power Point Tracking (MPPT) algorithm, automatically identifies 12V, 24V, 36V, 48V; Two USB 5V charging ports can quickly track the maximum power point of the PV system in any environment, with tracking efficiency no less than 99.5%. Significantly improves the energy utilization efficiency of solar systems.
