Pure sine inverter, 1000W
ALLWEI 1000W Pure Sine Inverter, ETL Listed Specs and Sizing
Researched from published standards and manufacturer specifications. Updated .
Quick answer
This is a specification sheet rather than a review. Every figure below comes from the manufacturer listing, and we do not test products in person. What this page adds is context: what these numbers mean for an RV system, and what else you need to buy alongside it.
Best for: A budget inverter with a real listing behind it.
ALLWEI 1000W Pure Sine Inverter, ETL Listed specifications
| Specification | Value |
|---|---|
| Watts | 1000 |
| Waveform | Pure sine |
| Input Voltage | 12 |
| Listing | ETL to UL 458 |

What does this component need alongside it?
An inverter needs short, heavy cable to the bank, a fuse at the battery end sized to the cable, and a battery BMS rated to supply the DC current the inverter pulls at full load. That last check is the one most often skipped.

- What is the ALLWEI 1000W Pure Sine Inverter, ETL Listed best for?
- A budget inverter with a real listing behind it. ETL listed to UL 458, which is the marine and mobile inverter standard and is worth looking for on a cheap unit. Confirm the current specification on the listing before buying, because manufacturers revise these products without changing the model name.
- Is the ALLWEI 1000W Pure Sine Inverter, ETL Listed suitable for a lithium system?
- Check the charge profile before pairing it with lithium. The requirement is a genuine LiFePO4 profile with the correct absorption voltage, not a lead-acid profile with a lithium label. Where a component only charges at lead-acid voltages, a lithium pack will sit permanently short of full.
- What size cable and fuse does it need?
- That depends on the current it carries and the length of the run, not on the component itself. Work out the current from its rating, then size the conductor for both ampacity and voltage drop with the wire gauge calculator, and fuse it at 125 percent of the continuous load rounded up to the next standard rating.
Wiring safety. Never exceed a conductor's rated ampacity, and always fuse a circuit at or below what the wire can carry, because the fuse protects the wire rather than the appliance. Fuse every positive conductor as close to the battery as practical. Use proper crimped lugs and heat shrink rather than twisted joints, support cable so it cannot chafe through on a frame edge, and keep the battery compartment ventilated. Permanent AC wiring is work for a qualified RV technician or a licensed electrician.
