Pramac 5.3kVA Petrol Electric Start Generator, S5000, 3 Year Warranty. The Pramac S5000 with a 3 Year Honda Australia Engine Warranty is a robust generator with all the top-class features required for domestic backup power for the home: a powerful and economical engine, a strong, modern design and a long-run 26.5L fuel tank. This unit is very popular for backup to off-grid solar applications and can also be used for Mains Power backup;


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.

Overall, this generator has the famous reliability of the Honda GX270 4-stroke engine which is matched by the maintenance free brushless alternator to generate maximum power of 5.3kVA and a continuous output of 3900 watts.

Together with the trusty electric start, a control panel that allows you to integrate the required accessories mentioned above, this is a high quality backup generator with a genuine Honda engine and national service network backing.

Q & A

  • I live off-grid in a solar powered home. If I were to install an auto-start generator to back up my solar, what connection type would I need?

    Hi Steve - great question! You would require a Two-Wire Auto Start Controller for your solar application; This device would connect between your auto-start generator and to your battery pack inverter connection. When your deep cycle battery packs run low, the controller will detect this and signal for the generator to automatically kick in so you will not be without power! It will also signal for the generator to stop once the battery packs are charged.

    This connection and installation needs to be undertaken by a qualified electrician.  

    The Two-Wire Auto Start Controller can be found under the Accessory List on the product page. 

    Hope that helps- Thank you!

  • 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.

A Serious generator

14 January 2015

As a first time generator buyer, I needed to know I wasn't going to buy something that would fail in a few weeks. I wanted a quality unit and something I knew would perform when I needed it. The unit was delivered with everything it needed except the oil and fuel of course. A quick run to the local servo with the manual in hand and I got what I wanted. Fuel in, Oil in and battery acid filled and its ready to go. The electric start is great and I bought this for the two wire start option which I need to work on configuring next.

Backup to site office solar

28 July 2014

Hi guys, just wanted to let you know how we are getting on with the 5.3kva genny. We've had it now for 3 months and it's been working really well. We've got a small 4kw solar system which often doesn't generate enough power to run the site office (depending on weather). This generator has been great and tops up our battery pack if and when needed. Thanks, Frank.
