Pramac Honda 7.2kVA AVR Petrol Generator with Auto Start capability. The S8000 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;
PRIMARY APPLICATIONS FOR THIS GENERATOR:
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.
ACCESSORY: AUTOMATIC MAINS FAILURE PANEL REQUIRED FOR MAINS POWER BACKUP
Overall, the generator is powered by a reliable Honda GX390 air-cooled engine with electric start to drive an AVR alternator for a max power of 7.2kVA and a continuous output of 5500 watts. The hardy design also features a long-run 26.5L fuel tank and control panel that allows you to integrate the accessories listed above as per your required backup use.
The twelve month warranty backed by a national service network means you can be confident you’ll always have power when the lights go out.

- Good generator for solar back-up Review by Aldwyn James , Upper Mangrove NSW

Product ReviewI bought a 8kVA honda generator from mygenerator.com.au 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.
Shopping ExperienceI received terrific advice from Sean over the phone who walked me through my options and relayed what I needed to ask my electrician throughout the process. Thank you for your help and the service.Recommend this product to a friend? yes(Posted on 1/13/15)

Product ReviewDuring 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.

Product ReviewI 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.
Shopping ExperienceThanks to the advice from the team at MyGenerator, both on the phone and the information onsite. Felt comfortable buying through guys who knew what they were talking about.Recommend this product to a friend? Yes(Posted on 7/28/14)

Pramac S8000 with Automatic Mains Failure Panel
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!
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.
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!
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.
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.
