This product is an off-grid modified sine wave inverter available in three models: DF-M03K, DF-M05K and DF-M08K, with rated power of 300W, 500W and 800W respectively. It supports 12V/24V DC input and is compatible with lead-acid and lithium batteries, achieving a maximum conversion efficiency of 93% while outputting 110V/220V AC at 50Hz/60Hz.
Equipped with an intelligent temperature-controlled cooling fan, the unit integrates comprehensive protection functions including battery reverse connection, over/under voltage, overload, short circuit and over-temperature protection, and resumes operation after faults are eliminated. It comes with a standard remote control switch interface and basic USB output, with fast charging modules optional. Designed for arid operating environments, it works stably at temperatures ranging from 0℃ to 40℃ and humidity of 0%-80%. Widely applicable to off-grid power supply scenarios such as households, offices, vehicles and yachts, each model features a compact size optimized corresponding to its power grade.
