Product Description

Pramac 11.9kVA Petrol Electric Start Generator, S12000, 3 Year Warranty. The Pramac S12000 with a 3 Year Honda Australia Engine Warranty is equipped with a reliable Honda GX630 engine, providing max power of 11.9kVA and a continuous output of 9100 watts. It comes with a strong, modern design and a long-run 24L fuel tank. This unit is designed for auto backup to either off-grid solar systems or auto backup to mains power; 


1) Backup to Off-Grid Solar: For backup power to off-grid solar systems, this generator requires a Pramac 2 Wire Auto Start Controller (see Accessories List above to add to your order). This controller connects between your Pramac generator and your solar system for automatic charging of your solar batteries when battery charge is low. A qualified solar installer / electrician is required to undertake the install and connection. Click on below image for a video demonstration:

2) Backup to Mains Power:  For backup power to your home/building when there is a mains power blackout, this generator requires an Automatic Mains Failure (AMF) Panel (see Accessories List above to add to your order)This panel is also referred to as an 'Automatic Transfer Switch'. This AMF detects when there is a mains power failure, and signals to the generator to automatically start up to restore power to your home/building. Conversely, as soon as the AMF detects mains power returns, it stops the generator. A qualified electrician is required to undertake the install and connection.

Customer Reviews

Pramac 11.9kVA Generator great perfrmance and valu Review by
I found the Pramac 11.9kVA Petrol Electric Start Generator a very good and well built unit. The generator is of basic but solid design, with 2x 15amp and 1x 32amp power outlets. It is powered by a very reliable electric start Honda petrol engine. Vibration and noise levels are low when running and is not that noticeable or disruptive. Although still only new, it appears suitable to run most appliances and pumps for our country home. I am happy with the unit and would recommend it as a backup generator.

Product Q&A

Ask Us a Question
  • I can see that with an auto-start generator, an “AMF Panel” is required for mains power backup, and for solar back up a “2 wire auto start controller” is needed. But if I'm on solar and mains, do I need both to go with my auto-start generator?

    Hi, firstly you are completely correct; to use your auto-start generator for automatic power backup, you need either:

    • An AMF panel for automatic backup to mains power, or
    • A Two-wire auto start controller for automatic backup to off-grid solar systems

    For homes on solar and on mains power:
    In this case, the solar charge is either used within the household consumption or fed back into the grid, meaning there are no storage batteries like there is for an off-grid solar system. So,if you require an auto-start generator to automatically start up to restore power to your home (which is on solar and mains power), you would need an accompanying AMF panel - an electrician would undertake the connection. When a blackout occurs, the AMF panel would signal for the generator to start and restore power to your home.

    For homes with an off-grid solar system:
    The Two-Wire auto start controller is only for off-grid solar systems, whereby the controller is connected to generator and the solar battery system. When the batteries run low on power, the controller signals to the generator to start up and restore power to the batteries.

  • Do I still need to maintain the generator even if it hasn't been required for back up?

    Howdy - yes you do need to provide some simple maintenance. It is advised that you start up and run the generator periodically to run the engine and ensure that all is working for when it is required for backup.

    Regular oil changes (inline with manufacturer guidelines) and inspections are also advised to ensure maximum performance.  The owner’s manual comprises full routine maintenance procedures and schedules.

  • What engine oil should I use with this Generator?

    Hi - the generator requires standard engine oil;  either 10W-30 or 10W-40.

    This is available from any local service station. Many thanks 

  • Can I install one of these auto start generators myself? How difficult is it?

    Hi Ron, installation of an auto-start generator to provide backup power for mains failure or backup to solar applications needs to be done by a qualified electrician. It is a failry straighforward job for an electrician.

    Cheers, Steve.

  • Can I use this generator to charge my power tool batteries?

    Hi there,

    Charging battery packs is fine from a conventional generator, we'd recommend having a steady load on the generator and don't connect appliances that will cause the load to jump around during charging.
