200W/300W/400W MPPT Solar Controller, Adjustable Voltage, Compatible With Acid Lithium Batteries

REAL TIME TRACKING FUNCTION: MPPT type is suitable for solar panels of different voltages, with high efficiency MPPT real time tracking HIGH CONVERSION EFFICIENCY: High efficiency synchronous rectifier circuit structure is adopted, which has high conversion efficiency in low power charging environment VOLTAGE ADJUSTABLE AND WATERPROOF: Output voltage is adjustable, support acid and lithium batteries, etc. Waterproof, dustproof, shockproof OVERHEATING PROTECTION: When the internal temperature exceeds 100°C, power reduces; at 110°C, automatically shuts off and resumes below 85°C. SHORT CIRCUIT PROTECTION: Automatically shuts off output during short circuits and resumes after removal. INPUT UNDERVOLTAGE PROTECTION: Shuts down below 15V and resumes when voltage is normal. OUTPUT ACTIVATE FUNCTION SETTING: Output activates with battery detection or can be disabled/enabled via [OK] key presses.
