S-2003 product is a high-intelligence solar off-grid or grid-tied energy storage power generation system, a complete set of comprehensive solutions for household lighting, electrical appliances, and other electricity consumption. It generates electricity through solar panels or via the 14.8V AC Charger (PWM controller stores DC power in lithium-ion batteries and uses high-frequency inverters to store DC power in lithium-ion batteries, converting DC power into AC power, pure sine wave 220VAC), which can supply household lighting, electrical appliances, monitoring, office, communications, and other electrical appliances and equipment. Product application 50W computer 4hrsd (at a time)35W*bulbs 10hrs (at a time)65W TV & Decoder 6hrs (at a time) Equipment name Total available duration (for reference only)There are 2 internal AC output ports. The product provides sine wave ACpower mainly for household appliances and equipment. Like laptops, IPAD,small printers, lamps and lanterns, fish tank heaters, photographic equipment,massage equipment, multimedia, and other electrical equipment.
