The safe route:
Quick tip: Search for Pramac AC03 manual filetype:pdf. Stick to official distributor sites (e.g., Pramac.com, Genpower.co.uk). Don't panic
Look at the control panel. See the screw terminal labeled with the earth symbol? The manual dedicates an entire safety section to this. Because the AC03 is a floating neutral generator, you must earth the frame if you are powering sensitive home appliances. Skipping this step is a shock hazard.
You might be tempted to just pour in gas and pull the cord. Don't. Here is what the manual tells you that common sense won't: If you can't find it on their site
Manual solution (Section 4.2 – Output Protection):
The AC03 has a reverse-polarity and short-circuit protection that disables output until reset. Disconnect the battery, wait 30 seconds, then reconnect correctly (positive to positive, negative to negative). If the issue persists, the manual instructs you to measure battery voltage – below 2V per cell triggers a "dead battery" detection (some models will not attempt to charge).
Note: If you own a Pramac AC03 Automatic Battery Charger (common in 12V/24V models), your manual will differ slightly from a Pramac AC03 inverter module. Always verify the exact model number on the device’s rating plate.
