Product Highlights

  • ✅ 【1500W PURE SINE WAVE INVERTER WITH TRANSFER SWITCH】- Converts 12V DC battery power into stable 120V AC household electricity, delivering 1500W continuous power and 3000W peak power. Designed for RVs, trucks, boats, cabins, and off-grid systems. Battery not included. This unit is not a battery charger and does not recharge the connected battery.
  • ✅ 【BUILT-IN 12MS AUTOMATIC TRANSFER SWITCH】- When 120V shore power is available, the inverter automatically supplies AC input power to connected appliances. If shore power is interrupted, it switches to battery-powered inverter output in approximately 12ms, minimizing power interruption. When shore power returns, the unit automatically switches back to AC bypass mode.
  • ✅ 【1500W CONTINUOUS / 3000W PEAK PURE SINE WAVE POWER】- Delivers clean, stable 120V AC power for compatible devices such as laptops, TVs, CPAP machines, lights, fans, small refrigerators, and other RV essentials. The 3000W peak output supports brief startup surges from compatible motors and compressors. Before use, check each appliance’s rated and startup wattage. Keep the total continuous load below 1500W and the startup surge below 3000W. Not recommended for high-power appliances that exceed these limits.
  • ✅ 【MULTI-PROTECTION & BATTERY CABLE GUIDANCE】- Built-in protection against low voltage, over-voltage, overload, short circuit, and overheating helps protect the inverter and connected equipment. Includes one pair of 16 mm² (approximately 5 AWG), 60 cm (1.97 ft) battery cables, suitable for short-distance installation and low-to-medium loads. For longer cable runs or continuous operation near the full 1500W output, use shorter, heavier-gauge pure copper cables with a properly rated DC fuse installed close to the battery.
