Overview
The SNTOOM 1000 W power inverter turns a 48 V DC battery supply into 220 V AC at 50 Hz, so mains-powered equipment can run from a battery bank, a vehicle electrical system or an off-grid solar installation. The output is a modified sine wave, which suits resistive loads and most universal motors: lighting, pumps, power tools, office equipment, chargers and small appliances.
Key features
- 1000 W continuous output and 2000 W peak for loads with high start-up current
- 48 V DC input, 220 V AC / 50 Hz output
- Universal AC socket plus one USB port
- Intelligent temperature-controlled fan that starts with load and stops when cool
- One-piece aluminium alloy housing, no welded seam to crack
- Green LED for normal output, red LED for overvoltage, undervoltage, overload or over-temperature shutdown
- Fixed mounting ears for wall mounting or flat placement

Typical applications
- RV and vehicle-mounted power
- Outdoor emergency supply for field work and temporary sites
- Small shop and kiosk backup
- Camping and off-grid power from a 48 V battery bank
Installation and operating notes
- Install in a dry location at 0–40 °C with 50 mm clearance for airflow
- Keep the total load within the rated 1000 W and start motors one at a time
- Switch off before connecting and observe DC input polarity
- A cigarette-lighter supply may limit output through its fuse; reduce the load or start the engine
