This document provides an overview of Honda generators, including their history, evolution, features, and product range. Some key points:
- Honda began producing generators in 1965 with small, lightweight models and has since innovated with many industry firsts.
- Modern inverter generators like the EU series provide pure sine wave output for electronics and features like Eco-Throttle for high efficiency.
- Larger commercial models like the EG series are suited for job sites.
- Honda's generators are known for their quality, durability, fuel efficiency, and quiet operation due to innovations like soundproofing and Eco-Throttle.
- The generator range includes portable models up to 7,000
2. Honda Generator History
• First model produced in 1965, 56
years ago
• E300 was 300W
• It could be carried in one hand
• Huge evolution since then with
many Honda world firsts
3. Honda Generator Evolution
• Early models were not pure
sine wave
• Early models couldn’t power
some devices
• Evolution over time to todays
pure sine wave inverter
models
• “i” denotes inverter type
• High quality electrical output
• Safe for all electronics
4. Eco-throttle - High Fuel Efficiency, Low Noise
• Inverter system allows “Eco-
throttle,”
• Eco-throttle automatically controls
the generator’s engine speed
according to the electrical load
• Under low-load conditions
operation time is longer, fuel
consumption is lower, and noise is
lower.
• Conventional portable generators
run at a constant engine speed
which means higher noise and fuel
consumption.
• Eco-throttle has high-output and
low fuel consumption/noise.
• Best of both worlds
• Eco throttle should be turned off
when starting high draw appliances
to allow the engine to be up to
speed for delivering larger amounts
of power more quickly.
5. Pursuing "Compact" and “Lightweight" that Match Ease of Use
• Compact
• Lightweight
• Low-noise
• Highly fuel efficient
• EU series released in 1998
• Completely new design
• Class-first microprocessor-
controlled sine-wave
inverter system
• Half the weight compared
to conventional generators
6. Double-soundproofing Structure
• Inner soundproof box encasing
the engine
• Outer soundproof box
• Foam seals on outer cover to
minimize sound “leakage”
• Made of resin (instead of steel)
to absorb sound and reduce
weight
• Corrosion resistant and
durable
7. Evolving to Make Generators Even More Commonplace
• Changing needs of consumers
• Not just construction sites and industrial uses anymore
• Consumers becoming more reliant on electricity with
computers and smart phones
• Home standby generators becoming more common
• Off grid solar/battery/generator hybrid systems now
being used
• Sophisticated electronics in off grid hybrid systems
require ultra clean power
• Customers require even longer run times, low noise
and greater fuel economy for overnight use without
refuelling
• EU70iS has fuel injection system to meet these
requirements
8. Todays Range

10. Generator Output
kW and kVA- They are not always the same.
• Most generator manufacturers quote the maximum output of their products in kVA.
• Then a “power factor” is applied, usually 0.8, to arrive at the actual usable kW’s the generator
• E.g. competitors 2kVA generator will only actually produce 2.0 kVA x 0.8 (power factor)= 1.6kW
• Honda generators have a power factor of 1. With a Honda generator 1kVA=1kW.
• kW’s are what does the work.
Honda generators consistently outperform other similarly sized competitor brands.
Generators have two types of output, Maximum and Rated.
Rated Output
• Maximum continuous output the
generator can sustain.
Maximum Output
• Peak output a generator can produce for
short periods of time.

All Honda Generators have 15 amp plugs as standard.
For appliances that require greater than 15 amps EU70iS with 32 amp plug option is required.
All Honda Generators Power Factor is 1 e.g. 1Kva = 1Kw
* at rated load
††dB refers to sound pressure level and is measured from 4 directions (front, back, right and left) by a microphone that is placed 7 metres from the product and 1.5 metres from the lawn ground. It is not measured in a closed room. Therefore, the data is affected by environmental
conditions such as temperature.
**LwA refers to sound power level and is measured at rated load, which is standardised by EU noise regulation. It is measured from 6 directions by a microphone placed 4 metres from the product in a closed anechoic room. This room is not affected by environmental conditions.
12. Types Of Generator Load
• 2 main types of generator load, Resistive and
Reactive
• Typical resistive loads are light bulbs, toasters,
heaters, hot plates, coffee makers, stereos, TV’s
etc. Usually do not contain electric motors.
• Typical reactive loads contain an electric motor.
• Reactive loads may require up to 3x as much
power (wattage) to start as it does to keep
running. It can be as much as 10x
• Typical reactive loads are power tools, bench
grinders, air compressors, air conditioners and
refrigerators.
• When sizing a generator for reactive loads you
must take starting, running and loaded power
requirements into consideration.
13. Generator Sizing
Key Points to ask:
1. What is the customers situation? Is the generator to be used for home back up, recreational, industrial application etc.
2. Ask what they want to power. Write down the appliances and find out their running watts usage. All appliances should have a tag
or sticker stating their usage. Honda only manufacture single phase petrol powered generators.
3. Do any of the appliances have electric motors? If so, estimate the start load.
4. How many of the appliances does the customer want to use ssimultaneously? E.g. Can they boil the kettle and then make the
toast? This will have a huge effect of the size of generator required for the customers needs
5. If possible, offer the customer choices based on their answers to the above. E.g. if you can boil the kettle and then make the
toast, then an EU22i will suffice, if you need to do both at once then you will need to step up to at least an EU30i.
6. Discuss features and benefits of the suggested model(s) that are suitable for their application.
7. Discuss the advantages of buying the Honda brand such as ease of use, high quality, excellent reliability, durability, low overall
cost of ownership (you buy cheap, you buy twice), spare parts availability, high resale values, and having your dealership based
locally to help with servicing or the unlikely event of a warranty issue.
8. Explain the Honda extended warranty period. Peace of mind.

14. Use the chart as a guide for your generator
selection - remember to:
1. Identify the products and/or tools you
intend to operate with your generator.
2. Determine the power requirement for
each product (allow for the starting
load).
3. Total up the wattage for the products
which may be operated simultaneously.
4. Choose a generator with a rated output
of at least your total, plus around 10%
contingency.
15. EU10i/EU22i/EU30iS/EU30iK Parallel Operation
• Double the power output by connecting
2x Generators together with a special
cable
• Generators must be same model (except
EU20-22 as below)
• EU20i s/n EAAJ-2032188 and later works
with EU22i
• EU20i s/n EACT-1000001 and later works
with EU22i
• Any of the 4 outlets on either generator
can be used to output up to 3600w (15
amp outlet limitation) or 2000w for
2xEU10i (maximum combined output)
16. Oil Alert Indicator
• All Honda Generators feature oil alert protection.
• Protects the generators engine from damage caused by
a low oil condition.
• Engine will shut down when all level is too low.
• Oil alert light will illuminate.
• Engine will not re-start until the engine oil level is above
minimum.
• Topping oil up is not an alternative to servicing!
• Honda generators require servicing including an oil
change after an initial 10-20 hours operation or first
month and then servicing every 100 hours or 6 monthly
after that.
For an extended 4 year consumer warranty Honda Power
Equipment engine oil is required to be used and the
product must be registered for warranty by the dealer at
the time of sale. Servicing must be completed by an
authorised Honda dealer for the extended warranty.
17. Overload Alarm
• Electronic overload protection (not a manual circuit
breaker)
• Upon overload the overload indicator will light up
and the output indicator will go out.
• The engine continues to run, but there will be no
electricity output.
• To reset unplug whatever made it overload, shut
down and restart.
This method of electronic overload protection stops
users from holding in or repeatedly pressing a
mechanical circuit breaker type of overload protection.
It makes users stop and think about what has just
happened and take steps to avoid it in future.
18. Output Indicator
• Green light for normal operation.
• Simple hour meter built in (EU22i only)
• Light blinks on start up
• No blinks: 0–100 hours
• 1 blink: 100–200 hours
• 2 blinks: 200–300 hours

is continuity between the 2 wires
• Smart logic system that tries 3 times to start the
generator and if unsuccessful then gives up and
returns to standby.
• Generator starts with the key in the off position.
This avoids draining the 12v battery when
standing by.
• Additional auto-start switch and isolation switch
added for safety during maintenance
• Ideal for use in solar systems to charge batteries
and as a house back up when an electrician has
installed an automatic transfer switch.
28. House Back up Generators
• When the power goes out, a generator can keep your house warm in winter or cool in
summer; it can keep your fridge and freezer cold, your kitchen cooking, and your laptops
and phones charging
• People tend to buy generators around major storms and natural disasters, when they’re
prone to making a rushed decision—without a plan for what to do when they get it home
• How many lights, tools and appliances do you want to run at once?
• 5Kw will usually cover the essentials in typical home
29. Supplying Electricity to Back Up a House
• Two main ways
1. The low cost way
• Uses multiple 15 amp extension leads plugged into the generator outlets
with multi boards connected to them.
• Passing cables through windows or doors is untidy and takes time to set
up
• Hard wired appliances like ovens and water heaters can’t be connected
• High draw appliances like water heaters can’t be connected with a 15
amp extension lead as they usually require more than 15 amps
2. Connect with a transfer switch and 32 amp outlet
The best way to back up a house is with a generator with a 32 amp outlet
and cable to a transfer switch which then connects to the house’s internal
wiring
30. Generator Transfer Switches
• A transfer switch MUST be used if connecting a generator to the buildings internal wiring or the generator
could back feed the grid and endanger line workers. This is a legal requirement.
• Without a transfer switch the generator could also back feed power to neighbours and overload the generator
• A Transfer switch can only be installed by a qualified electrician
• As a Honda dealer, you are not expected to be involved with supply or installation of a transfer switch, this is
a qualified electricians role
• There are two types of transfer switches
• Manual where the user must start the generator then switch over from mains to generator power
• Automatic transfer switches can be used with EU70iS with 32 amp outlet and auto start to provide a
seamless switch over with no user intervention
• With a transfer switch and additional electrical panel customers can choose which circuits in the building they
require to be powered depending on their requirements. For example, they may choose not to connect high
draw appliances like hot water, an oven or air-conditioning. This depends on the size of the generator and
what loads could potentially be applied to it. They may choose to power everything and load balance e.g. not
run the oven while water is heating
• Once power has been transferred to the running generator, appliances that are connected will work as
normal. Lights, power points etc.
A example of
a simple, low
cost transfer
switch
31. Typical Off Grid Solar Set up
• Generators are used to top up the storage batteries
when insufficient power is generated by the solar array
to keep the batteries at an acceptable level of charge.
• We usually see an increase in sales mid winter when
the sun is low, days are shorter and electricity usage is
higher than normal.
• The 240v output of generator is used via the solar
systems inverter/charger to charge batteries, not the
built in 12v DC generator battery charger
• Inverter/charger has to be set to not over load the
generator. Ideally at 80% of rated continuous load. E.g.
an EU70iS on this system should be outputting around
4.4Kw maximum This is done by the solar installer, not
you, but is an important set up process to protect the
generator from constantly overloading.
• The EU70iS generator 2 wire auto-start and 32 amp
plug is connected to multi mode inverter/charger (or
sometimes a separate controller). This controls when
the generator starts and stops based on the condition
of the batteries.
• These type of systems require synchronisation of the
generator output and inverter/charger. Honda
generators are perfect for this application due to their
high quality output. These systems can be fussy!
32. Generator Grounding
• Honda generators are not required to be grounded when connected to normal stand-
alone appliances suck as kettles, toasters, power tools etc
• Consult a registered electrical worker to determine if the generator is required to be
grounded when connected to a building or mobile installation e.g. food truck,
motorhome etc.
• This is the job of an electrician, not a dealer
33. EG5500CX(S) Open Frame Generator
• Two models, EG5500CX recoil start & EG5500CXS
electric and recoil start.
• 8.3 amp/12 volt DC,
• Maximum AC output 5.5 KW
• Large fuel tank capacity of 24 litres
• Continuous Operating Hours 8.1 at 5KW
• GX390 Engine
• Reduced noise with large muffler 71dB(A) @ 7
metres
• 2 x 15 amp outlets
• Dry Weight 89kg
• Optional wheel kit available
• Lead acid battery not included (source locally)
• Ideal for budget conscious consumers or
construction sites.
• Auto start is not available
34. Storage of Generators
• All Honda generators run on standard unleaded petrol.
• Premium or high octane fuel is not required.
• Fuel can go stale, typically in 6-12 months
• Fuel with ethanol have shorter shelf life.
• Run carburettor dry for storage of 3-6 months
• Use Sta-bil (available from Honda). Extends fuel life up to 2 years.
• Long term storage fuel tank and carburettor should be dry.
Always store generators in a well ventilated place away from any
appliance that operates with a flame such as furnace or water
heater to minimise the risk of fire caused by fuel vapours.
