g'day all. Looking a buying small generator either Honda EU10i or Yamaha EF1000IS. Both seem good units. Not sure which way to. However I've been told Yamaha parts are less readily available and are more expensive than the equivalent in Honda. Likewise to fix, the Yamaha is more expensive. Is this sales pitch or "real". I live in SA. Any advice appreciated. Helped before

Not sure what you are intending to power with the genny, but 1000 w genny seems a bit small. Most people will go for a 2000 w genny. As to which brand, IMHO, I think the Honda is better value for money, whilst more expensive, they are more reliable, and parts are more readily available. Macca,

thanks for the reply Macca. I need it to supplement solar. (combined 340Kw - 100w fixed and 240W portable) I have small van (14'), no airconditioning. only need to run lights, radio and recharge van battery if needed. Weight is an issue and the 1000w genny would be more suited.
thanks again

Sounds like a 1kVA would be the go. I would go the Honda - personal choice based on satisfactory experience with a 2kVA Honda.

Elsewhere there was mention of using a mains charger and not the 12V output. I support that, the 12V output is supply only, not really suitable for battery charging.

It might be worth noting that with 1kVA you might strike limitations on running your battery charger, depending on amps output of the charger and its design.
Some time ago a friend of mine had a 40A Xantrex Truecharge mains charger (for a bigger battery system than you have). The 1kVA Honda he had couldn't run it due to the poor power factor of the charger and the start-up current it needed. It worked fine with a 20A model of the same brand.

You won't run into that problem in a small system with a small charger and in any case good quality chargers have a better power factor these days, but if you already have a largish charger that you want to use it's a point that may be worth considering.

Either of those units represent quality and reliability. I have a the Yam 1k (still runs like a bird after several years of modest usage...mainly used to supplement solar for battery top ups on outback trips). Quite simple to change the oil* and clean the air filter...starts dead easy, every time. I bought a 2k Honda recently, mainly for domestic usage re power outages...and selected outback trips. Spend the $....look after the hardware...overservice as well (small amounts of oil = $peanuts)...you'll have the gennie for ages.

G'day Coolie
I presume you mean charging batteries via the 240v from a generator and using a good battery charger to do the actual charge work. A 1000W Nominal output is around 800 w output maximum if being used constantly.. My EU20i Honda is 1800w continuous maximum.

Although the generators do have a 12v charge out port, it is nigh on useless as it needs the gen to be running full speed and only delivers a few amps. If the 240v is used the charger or suitable size output can use the generator Eco function and not run at full speed, "quieter" and charge the batteries far mor efficiently and quicker.
Using the 12v side it may take days to charge your batteries, if it ever achieves it.

thanks for this. charging 110amp using CTEK system (in car) or plan to use 240V outlet to van, thru the onboard battery charger,

I had a Honda EU20i & I'm sure that you will find that the continuous rated output is 1600w.

Yes shaker you are correct. I was pushing it a bit. Thanks for the update.

Coolie

Yep either generator are excellent choices .

If I was going to buy one I would get the Honda .

But I would be happy with the Yamaha as well .



cheers

Flip a coin....both good units.
As said, only use it to power a battery charger, which I assume you have !!

A 1kva generator will not supply 1000w.

A Honda eu1.0 is 1kva, likewise the eu2.0 is 2kva.

To work out the available wattage (continuous) de-rate the kva rating by 20%

Eu1.0 = 800watt

Eu 2.0 = 1600 watt

This theory applies to any brand of generator.

Fully concur but back in day with SES we derated by 500w so a 2kva was able to light up 3 x 500w flood lights as maximum

I would still use this method today, but who uses 500w halogen globes these days apart from Street lighting

Think everybody has made their personal choices either way blue or red army both capable machines.

Folks have a blue army unit 1000 watt variant will charge the 2 x 100 ah batteries but very slowly -best my knowledge that was via 15a power inlet, but suspect going direct to charger unit maybe tad easier and less loss power wise and possibly quicker ?.

key thing is never leave petrol in generator fuel tank for long periods, folks unit (won in post bushfire raffle) old man went to power it up for whatever reason no go got me to go through start procedure choke etc - still no joy, despite emptying out old fuel and putting in a capful of new fuel, I didn't realise petrol colour had changed either.

I removed sparkplug squirt of aero start - reinsert spark plug, then few more pulls and all systems go, one capfull will run for approx 1 hour ! .

Here is another issue stuff all room to get to spark plug and remove with plastic housing around it. I just managed to remove it with just the little inspection plate removed for access any major servicing need to remove whole surrounding plastic outer housing special tools needed ?

Idea to check this out when your looking at sizes - maybe Honda has more clearance can't say just know how little room Yamaha has
