*[LED Green and Red Work Light]: When the 4000W/6000W modified wave inverter is working normally, the green LED light works to tell you that the inverter is working normally, but when the inverter is in a protection state, such as low voltage, high voltage , overvoltage, etc. In case of temperature, overload, etc., the red LED light will light up. *[Quick Charging Dual USB Ports]: The solar controller has 1 universal power socket, supports two USB charger ports (max. 2.1A) working at the same time, can charge mobile phones, computers, laptops, shavers and razors Charge. Medical equipment. *[Multiple Protection]: The solar power generation system has built-in fuses, safe charging designs and cooling fans to prevent the onboard power converter from overheating, saving power and energy, and has overvoltage, overload, overcurrent, short circuit, undervoltage, overheating, etc. *[High Efficiency]: The 100W solar folding panel uses high-efficiency monocrystalline cells with an effective conversion rate of up to 15%. Made of low-iron tempered glass, weatherproof EVA film, and high-quality aluminum frame, it is windproof and rainproof and can be used outdoors for more than 10 years.
