Built for Life Off the Grid: The MaxWatt MX12500AS 10000W Off-Grid Petrol Generator
If your power doesn't come from a reliable mains connection, you need a generator that can look after itself. The MX12500AS is made for exactly that. Its standout feature is a pre-installed 2-wire automatic control system, so it can start on its own to recharge an off-grid solar battery bank or carry the load when your storage runs low, then shut down when it's no longer needed. Behind that sits a big 550cc engine producing 9000 watts continuously and 10000 on start-up, fed by a huge 40-litre metal tank that runs up to 13.5 hours at half load. You get three weatherproof outlets including a 32A, an RCD safety switch as standard, and the choice of electric, recoil or remote starting. For a rural property, an off-grid setup or a serious worksite, this is a generator that does the thinking for you.

What This Off-Grid Generator Gives You
- Starts itself when you need it: pre-installed 2-wire auto start recharges an off-grid solar battery bank and feeds the load, then shuts down on its own.
- Big continuous output: 9000W running and 10000W peak from a 550cc overhead-valve engine.
- Runs a long time between fills: a 40L metal tank (the largest in its class) gives up to 13.5 hours at half load, 9 hours flat out.
- Three weatherproof outlets: 2 x 20A and 1 x 32A 240V IP66 outlets for heavy and standard loads.
- Safety as standard: RCD safety switch built in, meeting WH&S protection requirements.
- Clean, stable power: Senci copper-wound pure sine wave alternator with THD under 5%, safe for sensitive electronics.
- Start it your way: electric start, recoil backup and remote start all included.
- Made to be moved: never-flat heavy-duty wheels and a U-shaped handle.
- Ready to run: engine oil included, Euro V emission standard and a 2-year warranty.
