YN30-6.2KW-15KWH Specification
Function Overview
1. Heavy-Duty Appliances (Whole-Home Coverage)
With 6,200W of rated output power, this system can simultaneously run multiple high-draw appliances: Climate Control: Central air conditioning, multi-zone mini-split systems (including large 3-ton units), electric space heaters, and radiant floor heating. Kitchen: High-power induction cooktops, built-in wall ovens, full-size dishwashers, and commercial-grade espresso machines. Laundry: All-in-one washer-dryer combos, including the high-wattage heating cycle required for drying. Water Heating: Electric water heaters rated between 3kW and 5kW.
2. Sensitive & Professional Electronics
Pure Sine Wave Output: Delivers clean power that is equivalent to — or cleaner than — utility grid power, making it safe for high-end audio equipment, gaming PCs, and sensitive medical devices. UPS-Grade Transfer Switching (≤20ms): Functions as a true Uninterruptible Power Supply. In the event of a grid outage, connected servers, routers, and security systems will remain online without interruption or rebooting.
3. High-Impact & Industrial Tools
Motor Startup Loads: The 12,400W peak surge capacity is engineered to absorb the high inrush current demanded by motorized equipment such as air compressors, water pumps, and circular saws. EV Charging: Capable of delivering a meaningful charge to an electric vehicle through a standard Level 1 or Level 2 home AC charging outlet.
