Feature: 1. Efficient Charging: This boost MPPT solar panel regulator uses innovative MPPT technology with a tracking efficiency of up to 99% and a peak conversion efficiency of up to 98%, which reduces power consumption, generates less heat, and lowers operating temperatures. 2. Multiple Electronic Guards: This MPPT solar charge controller features multiple electronic guards, integrated with multiple guard mechanisms including overcharge, short circuit, and reverse current guard, which guards your devices and batteries from damage and provides a reliable and safe charging performance. 3. Compatible With Lithium Ion Batteries: This solar charge controller is compatible with lithium ion batteries, when the battery type parameter is set to lithium battery, the charging cycle setting will be changed accordingly. In addition, when the connected lithium battery is in a protective state, the controller will use the energy from the solar panel to activate the lithium battery with a current that does not exceed the lithium battery's protective voltage and current range. 4. Wide Application: This boost solar charge controller has a wide range of applications for electric cars, carts, scooters, tricycles, etc., and is compatible with a variety of battery types, such as sealed, gel, and FLD acid and ternary lithium batteries batteries. 5. Multifunctional: This MPPT charge controller boosts the voltage from 15V to 60V solar panels to charge 24V to 72V batteries in carts, electric vehicles and solar system kits. It is designed for situations where the photovoltaic input voltage is lower than the battery voltage, effectively boosting the voltage to meet the battery's charging requirements. Specification: Item Type: Solar Charge Controller Material: ABS, Aluminium Alloy Input Voltage: 24V, 36V, 48V, 60V, 72V Rated Charging Current: 10A Charging Technology: MPPT Charging Algorithm: 3 Stages Battery Voltage Range: 20-88V Operating Temperature Range: -35°C-65°C Humidity Range: 95%.
