Thread: Giandel Pure Sine Wave Inverters

Interesting reading the 'blurb' where it says ............... can be overloaded to 3300 watt ............... as well as continuous output power 3300 watt.
This translates to a 12 volt battery current of 275 amps and if the claimed surge power delivery of 6600 watts is to be believed then over 500 amps. By the look of the provided battery cables they would surely end up as a melted mess if used for the 'intended purpose', so I'd be a bit wary about the whole unit.

What sort of power loading do you intend using this inverter for ?

Thanks for your thoughts Deano, hence why I asked the question. I am also sceptical about these sorts of devices at theses sorts of prices. A reputable brand like Victron would be 8 or 10 times the price for the same spec.

I will be running toaster/microwave/fans/PC's & occasionally the aircon (if it will start it) so 12V/150A would be the maximum continuous draw. I am under no illusions about the cabling supplied & will change it for something suitable like 25mm2 battery cable or tri rated switchboard cable.

There is always ebay's dispute process if it fails to meet expectations i suppose.

Thanks

360AH is a Lot of stored power But an air con and occasional use of the toaster/Microwave will eat that energy up pretty quickly.
I have a similar inverter (2000w) and it powers my small inverter stick welder and microwave that I take away on trips easily But I haven't used it continuously for any length of time so I don't know if it can handle a continues draw of high ampage use.
I only paid $150-$200 for the inverter and for what I use it for I find it to be great value for money.

I am interested to see how yours performs $335.99 is Not a huge outlay so I think that I is probably worth giving this a go.

Any wattage calculations you do need to be x 1.2, or add 20% at a minimum. They are also very inefficient at low loads and will probably draw a lot more than you realise.

I would not even attempt to run an air conditioner off a unit of that size.
Intermittent use of a toaster and / or microwave would probably be ok, but make sure the inverter is operated in a well ventilated cool place.
These things also need a good ground wire. They put out a lethal voltage just the same as the mains.

Based on the output versus price is will be just like any other cheap Chinese inverter - it should work fine for as long as it works.

If you've lashed out on a 360Ah battery why scimp on a crappy inverter? A good one that's capable of 3000 watts would be $1,500 plus but you get what you pay for.

I've got an Aussie made Selectronic unit but I don't think they make them any more - but worth looking for a second hand one - they are bullet proof but very large and heavy compared to the cheap versions.

My 600 watt unit (peaks at 1,500 watt for 2 minutes) were going for near $1000 new, years ago but I snagged mine second hand for $400. Has an auto sleep mode so doesn't draw power when not in use which inverters do - a unit like that would draw around 2 amps sitting there doing nothing.

Also, most cheap units aren't suitable to hard wire into an isolated power system like a caravan as the neutral can't be earthed without damaging the unit usually.

Hi, I am using a 2800 - 5600 Giandel Pure Sine Wave inverter in the caravan.

I have about 250 Watts of solar panels, 2 X 100 AH Lead Crystal batteries (real good things from Traxide).

I can run the roof top air conditioner for at least two hours (haven't tried longer).

The inverter is mounted under a seat in the caravan so the wired remote is handy, just ran the wire to a suitable available spot to turn it on and off.

It was supplied with twin wiring to carry the load but I went to an auto electrician and had heavy right length cables made to suit.

I'm happy with the unit, I considered a 2800 was plenty big enough with the 5600 kicker on air con start up. Incidentally, they recommend to turn the load on first and the inverter does a soft start.

Cheers

Oh as per another post on here, these have an external earthing post so they can be made safe.

At $269 for my 2800 vs your over $1500 I look at it like this.

Mine only lasts, say three years and yours lasts fifteen years, I'm in front, mine cost less that $100 a year yours cost $100 a year.

Now if mine lasts five years I'm miles in front value wise, as I have one of these Giandels I can tell you they are not 'crappy' as you suggest.

When Japanese cars first came on the market they were sneered at.

When Korean cars first came on the market they were sneered at, both with good reason but we don't sneer at them now.

I really wish I could buy Australian but until they, or we, become price competitive unfortunately it aint going to happen.

Tindel Solar here in SA have done it, better quality than any where else and at equal or better pricing, the other companies just have to catch up.

Having said that we are all driving imported vehicles, Land Rovers.

But is the Neutral at earth potential? Just earthing it isn't enough...

To be used safely in a caravan either the electronics need to hold the neutral conductor close to earth potential or the neutral itself needs to be earthed - which will kill some inverters.

Not saying those aren't big most Chinese units aren't the best is all.
