Question about Honda 3000 Watt Portable Generator

2 Answers

I have a honda eu3000is generator connected to a Atkinson GSCM that supplies AC power to a Outback invertor/battery system. It is a new installation and my battery went dead. We are using a pilot relay so that the the ignition can remain in the off position. Why would my battery go dead and being a stationary unit can I upgrade the battery to a auto battery. Would there be any benefit to to that?

Normally speaking the battery should not be discharge easily,

unless for some reasons.

• One remedy for troubleshooting is to charge the battery

( you may need to disconnect it from the generator

wiring ) and check on it . ( with a Multimeter and a load )

• Second check the Battery if it is being charge while the engine

is running. ( Can use a series 5A DC Ammeter when checking )

Since it is also disconnected temporarily , you might as well

consider having an Automatic charger connected to it., later.

( externally speaking )

These Automatic charger would insure that there is always a

charge for the battery , to insure that the generator will run

when Power Failure occurs.( If the built-in charger wont do )

• Some generators main function is to produce an AC output.

not to recharge the battery when it runs.Charging is done

manually or external automatically. Yours ( Honda )only charges

at about 0.5 amp , when the engine is running.

• If you prefer to replace the battery , same symptoms

might still occurs, unless it has higher capacity ( amperes )

not voltage , to insure that it can make the starter motor runs.

• You can double or triple current rating but not voltage rating.

here are additional details should you need one :

    • It is also good, I do remember one time I have seen one, or similar

    like that , installed at the back of the car.

    • it helps in recharging the battery even when the car is not running. For

    as long as there is available and adequate sunlight or similar

Hello. There are a couple of reasons why a battery goes dead, the most common one being that there is a drain on the battery which has to be located and fixed. You can upgrade the battery as long as you are sure that the voltage on the new battery is the same as what you have now. The new battery will have more amperage which simply means that is it indeed "bigger".

Honda eu3000is generator surges

Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

Does a battery need to be installed in a EU3000is honda generator to run it or will it run fine without it?

I would say it can run fine without a battery. Make sure the battery cable terminals are taped up to prevent shorting out and damaging at minimum the charging circuit.

I'm dumb. Can I hook an inverater to my generator and produce more enegry than my generator produces???

Please understand that the generator produces power from fuel with an engine wheras the invertor is one which genrerates power from a stored battery using the principle of frequency switching a DC source to induct and produce AC.
Now you can have an uninterupted power supply setting with the invertor backed up by the generator so that when the battery voltage goes down you can start and charge the invertor and also supply the extra energy .
the ratings of both must also be considered.

Honda EU30001 generator causes erratic pellet stove operation.

Ok Motors and the like generally DO NOT really go all that well from a generator, what load does the Stove use?, You must add up the cumlitive "Wattages" of ALL things connected, see your generator is about 3000 Watts, 3KW, How much "headroom" is there between the two? Whats supplied versus whats being used? Purely inductive loads, like Motors etc, are less responsive than electronic loads. I suspect that your generator is NOT providing enough current to the Stove, especially when "Other" things are connected. also. Look, if the, any, generator is 3000 Watts really you should only load it up to a couple of KW's, 2.5KW being about maximum. To do what you are doing would require, IMHO, at least, 5KW, to get the "Headroom" of current drawn over current able to be delivered by the generator. Also inductive loads loose heaps of power and actually cause a higher draw. So that your answer, you must use it well, inside it's rating, not right up to the limit.
