1500W Pure Sine Wave Inverter with 3000W Surge (5s max), 12V DC to 110V AC Converter, 3x AC Sockets, GFCI Protection, 94% Efficiency, Solar Power Inverters for RV, Truck, Home, Off Grid

The HQST 1500W Pure Sine Wave Inverter converts 12V DC into clean, stable 110V/120V AC power, delivering a true 1500W continuous output with 3000W surge capacity (5s max) to start high-inductive appliances including refrigerators, freezers, compressors, sump pumps, microwaves, and small power tools without voltage sag or mid-use performance drop. Built-in soft start technology reduces inrush current for smoother, safer startup and added protection for both the inverter and connected devices. With an ultra-low 3.52% THD (half load) — far cleaner than modified sine wave inverters at 20~40% THD — it delivers grid-like power for sensitive electronics such as CPAP machines, laptops, TVs, car stereos, and routers, reducing electrical noise, heat, and performance interference. Up to 94% conversion efficiency maximizes battery runtime and minimizes energy loss, making it ideal for solar and off-grid systems. Safety is comprehensive: built-in GFCI protection reduces electric shock risk in wet or outdoor environments, while overvoltage, under-voltage, overload, overheat, and short-circuit protections guard both users and equipment. Dual cooling fans auto-activate when temperature exceeds 113°F or output surpasses 50% load for stable thermal management, and protective terminal covers further reduce short-circuit risk during installation. Three AC outlets and a QC 3.0 USB fast-charging port power multiple devices simultaneously, while included battery cables and 6 extra fuses allow quick, reliable installation. Compatible with 12V (12.8V) battery systems, it integrates seamlessly with HQST LiFePO4 batteries, solar panels, and MPPT charge controllers, making it the ideal power solution for RVs, trucks, camper vans, off-grid cabins, marine use, and emergency backup power during outages, snowstorms, or hurricanes.
