Hi all

Just wondering if anyone has bought a Sidewinder generator from Derek at ABR and if so, your opinion on them please.

Thanks in advance

Mrs W

My information is that the firm in China that makes them stopped producing at the end of October 2007 and looks like folding due to poor quality that created a loss of customers.

This is no reflection on Derek as maybe he is not yet aware of it but if I was you I would need some assurance on whether this is correct or not but Im sure that Derek would stand behind whatever he sells .

Hi Mrs W

No the company that manufactures them has not closed down and they have just completed our new order. The container is due on the 6th of Feb 2008 and we will have plenty of stock including spare parts.

There was some restructuring of the manufacturing plant and we had a delay in our shipment of 3 weeks. Our comparison test between the Honda eU20 and the Sidewinder 3000i went well.

Our sample unit has been in test for 6 months now and still going strong.

Regards

Derek.

Derek, on paper they look good, and quiter than the Hondas by about 4 db. Is that your real world experience?

Also the 12v looks great to give a quick boost to batteries. However I am considering if I need 240v at the moment.

I have a few questions if I may, hopefully these will help Wilgadine too.
Does the 240v unit put out 240v at 10A AND 12v at 8A at the same time? (240x10.4 + 13.8x8.3 ) = 2610W.
Am I right to assume the 12v is really 13.8 or so for charging?
Is it a modified or true sine wave? Engles have difficulty with many devices like aircons.
Do you see any reason why I couldn't put a standard mains powered 20A battery charger on it for a more rapid charge ( apart from it being only 80 - 90% efficient)

Thanks

Hi Tony

The 12V out does not effect the 240V side of the generator and I would recommend a 240V Smart Charger as the 12V out is unregulated and can over charge batteries if left for too long.

These are pure sine wave and run a/c and refrigerators fine, our test side by side with a Heron 2.2 a/c and a 30A Smart Charger showed the Honda to be the same in noise but the Honda would stall if the charger was switched on first before the a/c.

Regards

Derek.

Sounds nice.

What would I expect to see on the unregulted 12v under say a few amps, and full load. Could I put an external 13.8v regulator on it and still have it charge?

Just don't use a shunt type solar regulator, as these will only work with the constant-current output of a solar panel.

They will produce 13.5 volts on smart throttle and 14.5 volts at full speed.

I would recommend a automotive external regulator if you wish but a 10A charger is more cost effective.

I only use my 12V output to run a camp light.

Hmm not bad.

Based on that I would probably do as you say and use a 240V battery charger unless the 240V is loaded up, and then use the 12V with a timer which can be set to a few hours then cut out for the barreries. Though tt would be unlikley to be running for a few hours anyway but you never know what can happen if I am having a few tinnies, in that case the timer might be the fuel.

Hmm those beers are cutting in now.

Batteries not barreries, and it not tt.

Mike, that does not make any sense at all.
Solar panels do NOT have a constant current output, just watch an amp meter connected between panel and battery on a cloudy day.

Shunt regulators are exclusively for wind generators, they 'shunt' (reroute) the output to an external load when the battery gets full.
Why? you cannot just remove the (battery) load from an operating wind generator as it will then overspeed and possibly self destruct.
I hope that clears it up a bit for you.

Klaus, if you have a look at the output graph of ANY solar panel you will see that the current varies very little as the load is increased - there is little difference between the current at normal charging (at 15 volts) and the current into a short circuit.

This is all referring to the current output at the same level of illumination - after all, the regulator isn't going to wait until the sun goes down to stop overcharging the battery.

The shunted current can be used to heat water.

Just because nearly every other electrical source we have is constant-voltage, it's seems to be really hard for people to accept the concept of a constant-current source.

Boys
'Shunt' <-is what trains do when they move carriages from place to place in the rail yards :-)

I've never heard of a wind generator self destructing when battery is disconnected

if your need is only to charge a battery and a bit of 240 Bunnings have the GMC 1000w inverter generator for $599. Is a Kipor and has been top tested model. For battery charger KMart have 16a top quality 4 stage charger $99. In tests outperforms all other chargers up to 20a and charges flat batteries.
in power outage at home the GMC 1000w inverter powered the big fridge TV and light for 5 hrs.
GMC 2 yr replacement warranty and spares backup.
dont buy generator bigger than you need or unknown brand here today gone tomorrow no longterm spares backup.
