Product Description

Pramac Honda 7.2kVA AVR Petrol Generator with Auto Start capability. The S8000 with a 3 Year Honda Australia Engine Warranty matches easy-use features and first-class components with the legendary Honda reliability to satisfy your home back-up power needs. This model is one of our most popular units for off-grid home solar power back up and can also be used as back up 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.

Awesome Generator Review by
Great Generator, I have bought this one to replace my old generator. This is used for off grid solar backup. Very Impressed with the quality of this generator and how quiet it is compared to the last generator. Would highly recommend this generator for solar backup.Two wire controller very easy to install. Only one thing to be aware of is the Men ( Multiple Earth Neutral Link ) needs to be disabled on the generator to stop it from tripping continually when used for charging batteries in your off grid solar system.

Good generator for solar back-up Review by
I bought a 8kVA honda generator from about 6 months ago. Really impressed with the machine with its start function. Haven't had any dramas. It's hooked in to our solar system to top up the deep cycle batteries. Auto start so it kicks in when required. Delivery took 5 days which was fine. Highly recommend for solar back up.

Impressed Review by
During installation, my electrician commented that he was impressed with the unit and the connecting controller. After a full winter, I too am impressed - it's started and stopped automatically as hoped and topped up our deep cycle packs when needed. It really has been seamless. I've checked oil levels periodically, but otherwise haven't needed to do anything. Thank you guys.

Good Option for Solar Backup Review by
I bought this model 6 months ago to use as a backup power source to my 6kw solar system. It's been working really well so far and hasn't skipped a beat during winter - when i need it most. I did a lot of research on auto start generators. This model is about half the price of some local auto start brands. Handy to have the Honda engine also.

Product Q&A

Ask Us a Question
  • 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.

  • Does this generator have automatic choke?

    Hi there, The S8000 generator has an electric solenoid to pull a choke lever within the carburettor. It get energised by the push button on the instrument panel when manually starting the unit.

    When used with the two wire start controller this solenoid is also energised at the same time as the starter motor.

    The P6000 has a diesel engine and doesn’t utilise a choke solenoid at all but will start very well as they are a compression type fuel system. Thanks

  • 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.


  • What size auto-start generator would you recommend to backup a normal sized home? (say 3 bed, 2 bath sized home). Would this model do it?

    Hi Trevor; we get this question quite a bit. Obviously it depends on the type of appliances in your home and how many you are running. Typically for the standard sized home you are talking about, a generator between 5 - 8kVA will generally do the job to power your whole home. Appliances such as lights, TV's, computers, standard fridges and most kitchen appliances don't tend to draw massive amounts of power. You should just be conscious of other items such as A/C units as well as things like kettles and hair dryers which can require more start up power. 

    As mentioned, each house is different, so if you want to be completely certain, you could ask an electrician to do a proper wattage meter reading on your home. Thanks!
